Abstract
The main synthetic approaches for the preparation of porphyrazines are outlined. In addition, some structural and spectroscopic properties, especially the UV-vis absorption profiles emanating from their peripheral functionalization, the modification of the tetraazaporphyrin skeleton or the arrangement of macrocycles in a supramolecular manner, are discussed. Cyclotetramerization of appropriate dinitrile derivatives or modification of peripheral substituents on porphyrazines constitute the main synthetic routes. Moreover, the use of special templates, as well as different intermediates or nonpyrrolic precursors, are tools for the attainment of azaporphyrin analogues of distinct nature and unusual characteristics.

Abstract
The quasi-line fluorescence and fluorescence excitation spectra of 2,3,12,13-tetrame-thyldibenzoporphine have been obtained at 77 K in n-octane and analyzed. The normal-coordinate analysis of this molecule has been performed, and the spectra have been interpreted in detail. In the Soret band region the fluorescence excitation quasi-line spectra clearly reveal two 0-0 components. The problem of the nature of the Soret band of free-base porphyrins is discussed.

Abstract
The condensation reaction of 2-amino-3-[(3-pyridylmethyl)amino]-2(Z)-butene-1,4-dinitrile with a series of diketones led to novel dinitriles, of which 2-(2,5-dimethyl-1H-pyrrol-1-yl)-3-[methyl(3-pyridylmethylene)amino]-2(Z)-butene-1,4-dinitrile, the product of the Paal-Knorr reaction, was successfully utilized in the Linstead macrocyclization towards symmetrical and unsymmetrical porphyrazines. NMR and X-ray study revealed an almost perpendicular orientation of the pyrrolyl groups in relation to the porphyrazine platform. The newly synthesized macrocycles with different peripheral groups show interesting spectroscopic and electrochemical properties. Due to selective sensor/coordination properties they are expected to find applications as chemical sensors and electronic materials.

Abstract
It is rare that such a diverse array of applications can be realized from a single basic molecular unit, however, such is the power of the tetrapyrrolic macrocycle motif. Indeed, their potential in areas such as chemical dyes, optical sensors, optoelectronics, and biomedical agents is a function of their rich electronic and optical properties. While the naturally occurring porphyrins and the synthetic phthalocyanines have been extensively studied, the related tetraazaporphyrins or porphyrazines remain comparatively underdeveloped. Since porphyrazines maintain a unique position in this family: analogous derivatives are virtually inaccessible for the porphyrins, and direct fusion of heteroatomic substituents onto the porphyrazine β-positions results in a more pronounced effect compared with the substitution of an equivalent group onto the benzenoid rings of the phthalocyanine; a driving force exists to further explore the synthesis and applications of these novel macrocycles. This review will provide a historical overview of the synthetic strategies towards functionalized porphyrazines and describe new strategies towards the preparation and applications of heteroatom-appended porphyrazines, particularly in the context of their multimetallic complexes, catalysis, surface chemistry, and as biomedical agents.

Abstract
Crossover Linstead macrocyclization of a doubly norbornenyl-functionalized dimercaptomaleonitrile with dipropylmaleonitrile gave a crude mixture of porphyrazines containing the hexapropylporphyrazinedithiol magnesium complex. The mixture was subjected to ring-opening metathesis polymerization to yield the insoluble porphyrazinedithiol-functionalized polymers. Cleavage from the polymer backbone using mercury(II) acetate followed by reaction with electrophiles gave access to a range of thioporphyrazinedithiol derivatives including solitaire porphyrazines. Studies into the possible uses of hexapropyl-2,3-di-(carboxymethylthio)porphyrazine in sensing metal cations in solution are described.

Abstract
Reduced symmetry phthalocyanines are finding use in an increasing number of industrial applications. A detailed understanding of the electronic structure of the pi-system will greatly facilitate the design of new complexes, which fit the specifications required in many of these emerging high technology fields. NMR, electronic absorption, magnetic circular dichroism (MCD), and fluorescence emission and excitation spectra have been recorded for five generic metal phthalocyanine (MPc) derivatives in which additional benzene rings are fused either radially or obliquely onto at least one of the four peripheral benzo groups. The spectroscopy of four radially substituted compounds, zinc mononaphthotribenzotetraazaporphyrine (Zn3B1N), zinc monobenzotrinaphthotetraazaporphyrine (Zn1B3N), and two cis and trans zinc dibenzodinaphthotetraazaporphyrine (Zn2B2N) isomers, is compared to that of the obliquely fused structural isomer of Zn3B1N (Zn3BoN) and the D(4)(h)() symmetry parent compounds, ZnPc and zinc naphthalocyanine (ZnNc). The selection of Zn(II) as the central metal eliminates the possibility of charge transfer between the metal and ring. None of the complexes studied contain any sigma-bonded peripheral substituents. (1)H NMR signals of the seven compounds are assigned on the basis of the coupling patterns, integrated proton numbers, and decoupling experiments. The SIMPFIT program was used to perform spectral band deconvolution analyses of absorption and MCD spectra. ZINDO molecular orbital calculations are described, and the optical spectra are assigned on the basis of the MO models that have been developed previously to account for the spectral properties of metal porphyrin (MP(-2)) and metal phthalocyanine (MPc(-2)) complexes.

Abstract
We report the synthesis and physical characterization of a series of peripherally functionalized porphyrazines (pzs) of the forms H2[pz(A;B3)] and trans-H2[pz(A2);B2], where A is a dithiolene chelate of molybdocene or vanadocene and B is a solublizing group. The precursor pz's 8 and 9, of the form H2[pz(A;B3)], where A = (4-(butyloxycarbonyl)-S-benzyl)2 and B = di-tert-butylphenyl (8) or di-n-propyl (9), have been prepared, deprotected, and peripherally metalated with molybdocene and vanadocene to form 1(Mo(IV)) and 1(V(IV)), prepared from 8, and 2(Mo(IV)) from 9, respectively. Likewise, the protected trans-H2[pz(A2);B2)], where A = (S-benzyl)2 and B = 3,6-butyloxybenzene (12) or A = (S-benzyl)2 and B = (tert-butylphenyl)2 (13), have been prepared and peripherally metalated with molybdocene and vanadocene to give the trans dinuclear complexes, 3(Mo(IV),Mo(IV)), 3(V(IV),V(IV)) (from 12), and 4(V(IV),V(IV)) (from 13). A crystal structure of the trans vanadocene pz 4(V(IV),V(IV)) is presented; the distance between the two vanadium atoms is 14.5 A. The molybdocene-appended pz's are highly redox active and exhibit cyclic voltammograms that are more than just the sum of the metallocene and the parent pz's. Chemical oxidation with FcPF6 gives the Mo(V) species 1(Mo(V)), 2(Mo(V)), 3(Mo(V),Mo(IV)), and 3(Mo(V),Mo(V)). Their EPR spectra are indicative of extensive delocalization from the Mo(V) into the dithiolato-pz. The EPR spectrum of the mononuclear paramagnetic vanadocene pz, 1(V(IV)), shows an expected 8-line pattern for an S = 2 system with hyperfine coupling to a single 51V (I = 7/2) nucleus, but the dinuclear vanadocene pz's, 3(V(IV),V(IV)) and 4(V(IV),V(IV)), exhibit a striking 15-line pattern of the same breadth from the S = 1 state formed by exchange coupling between the S = 2 vanadium centers of a dinuclear complex. Thus, the porphyrazine macrocycle is capable of mediating magnetic exchange interactions between metal ions bound to the periphery, separated by 14.5 A.

Abstract
Metal-free and copper porphyrazines, [H(2)pz] and [Cu pz], have been fused at the periphery with molybdocene dithiolene, [Cp(2)Mo]. The optical, magnetic, and electronic properties of the resulting neutral and cationic complexes are studied, using first-principles density functional theory implemented by the discrete variational method. Analysis of the charge and spin distribution shows that the porphyrazine core is strongly coupled with the peripheral complex. The calculated optical absorption is found to be in reasonable agreement with experimental spectra, lending support to our theoretical model. Under appropriate circumstances one observes interaction of unpaired spins localized in the vicinity of both metal sites. The calculated spin distribution shows that [Cp(2)Mo][Cu pz] and [Cp(2)Mo][H(2)pz](+) have a magnetic moment of 1 micro(B) while [Cp(2)Mo][Cu pz](+) and [Cp(2)Mo][H(2)pz] have no moment, in good agreement with the results of X-band EPR spectra. The Cu-Mo magnetic interaction is antiferromagnetic, being mediated by pyrrol nitrogens, meso nitrogens, carbons, and sulfurs.

We report the synthesis of porphyrazines (pzs), or tetraazaporphyrins, of the form H2[pz(An;B4-n)], where A is [S(CH2)3COOR]2 (R = n-Pr,H) and B is a fused beta,beta'-diisopropyloxybenzo group, including the compounds with n = 4 (6), n = 3 (7) and the trans compound with n = 2 (8) (Scheme 1). The synthesis employs Linstead crossover macrocyclization of dimethyl 6,7-dicyano-5,8-dithia-6(Z)-dodecenedioate, MNT(C4O2Me)2 (2), with 1-imino-4,7-bis(1-methylethoxy)-1H-isoindole-3-amine (4). These pigments were characterized by 1H NMR, 13C NMR, absorbance/fluorescence spectroscopy, mass spectrometry, and microanalysis. An X-ray crystal structure of 8 is presented. Of particular note, 6-8 display intense near-IR absorbance and dual UV-visible/near-IR emission which are very important in potential biomedical applications, both for cancer therapy (photodynamic therapy, PDT) and cancer diagnosis (optical tumor imaging). For example, the trans-porphyrazine 8 has an intense long-wavelength absorption at ca. 800 nm (log epsilon = 4.18) and S1 fluorescence at approximately 820 nm, where mammalian tissue is effectively penetrated by light. Transformation of the ester group permits a wide range of functionality and solubility to be generated without change in optical properties. As an example, hydrolysis of these compounds by LiOH in THF/H2O gives the corresponding carboxylato-functionalized pigments 9-11, which are described. The last of these dissolves without aggregation in fetal calf serum.

Abstract
The synthesis and isolation of unsymmetrical porphyrazines bearing two, four, and six bis-(dimethylamino) functionalities has been achieved via the base-catalyzed cross-condensation of 1,2-dicyanobenzene 8 and bis(dimethylamino)maleonitrile 7. In addition, the benzo-fused hexaaminoporphyrazine dimer 10 was prepared from condensation of dinitrile 7 (in excess) with benzenebis(1,3-diiminopyrroline) 9. Electrochemical studies reveal that all porphyrazines may be readily oxidized. The X-ray structures of porphyrazines 2b and 5a and the cis isomer 3a are presented. The latter is the first structure of a porphyrazine having a cis-type substitution pattern. The extended pi-conjugation in dimer 10 causes a approximately 100 nm red-shifted Q-band in the electronic absorption spectrum.

Abstract
The first metalated porphyrazinediols 11 have been prepared from (L)-(+)-dimethyl tartrate via conversion into the corresponding dispoke or 2,3-dimethoxy-2,3-butanediyl protected 2,3-dihydroxymaleonitrile, Linstead macrocyclization, transmetalation, and deprotection. Their stability is very dependent on the nature of the metal ion in the cavity of the porphyrazine. Reaction of these porphyrazinediols with metallocene dichlorides led to new solitaire porphyrazines 12 while DDQ oxidation followed by trapping with diaminomaleonitrile afforded new porphyrazine dinitriles 14.

Abstract
The unsymmetrical porphyrazine (tetraazaporphyrin) bearing a single peripheral bis(dimethylamino) functionality, Mg[pz(NMe(2))(2)(Pr)(6)], was prepared by base-catalyzed cross condensation of dipropyl maleonitrile (in excess) with dimethylamino maleonitrile. The freebase (2H[pz(NMe(2))(2)(Pr)(6)]) and centrally metalated forms (M[pz(NMe(2))(2)(Pr)(6)]; M = Ni(II), Cu(II), Mn(III)) were prepared by treatment of Mg[pz(NMe(2))(2)(Pr)(6)] with trifluoroacetic acid and then the appropriate metal salt. PdCl(2) and PtCl(2) were coordinated to the peripheral bis(dimethylamino) chelates, yielding the bimetallic complexes, M[pz(NMe(2))(2)(Pr)(6)]M'Cl(2) (M = Ni, Cu; M' = Pd, Pt). The heteroleptic [N(2)-Pd-S(2)]-capped porphyrazines were prepared readily by substituting the chloride ions of M[pz(NMe(2))(2)(Pr)(6)]PdCl(2) with the dithiolene chelates, maleonitriledithiolate (mnt(2)(-)), benzenedithiolate (bdt(2)(-)), and 1,3-dithiole-2-one-4,5-dithiolate (dmid(2)(-)). The [N(2)-Pt-S(2)] complexes were prepared by reaction of M[pz(NMe(2))(2)(Pr)(6)]PtCl(2) with the dialkyltin-protected dithiolates dibutyltin(toluene-3,4-dithiolate) and dibutyltin(dmit). The peripheral heteroleptic [N(2)-M'-S(2)] core was found to be electroactive for electron-rich dithiolene ligands (bdt(2)(-), E(1/2)(Pd(III)/Pd(II)) = 0.22 V; tdt(2)(-), E(1/2)(Pt(III)/Pt(II)) = 0.20 V; dmid(2)(-), E(1/2)(Pd(III)/Pd(II)) = 0.19 V; dmit(2)(-), E(1/2)(Pt(III)/Pt(II)) = 0.19 V) but not for the relatively electron-poor dithiolene, maleonitriledithiolate (mnt(2)(-)). The X-ray structure of Ni[pz(NMe(2))(2)(Pr)(6)]Pd(mnt) (13) was determined. Crystal data for C(85)H(109)Cl(3)N(24)Ni(2)Pd(2)S(4): space group P2(1)/n; a = 17.435(4) Å, b = 17.982(2) Å, c = 30.577(2) Å; beta = 104.27(2) degrees; Z = 4.

Abstract
The amino-functionalized porphyrazines 1, 2, and 4 and norphthalocyanines 3 and 5, which were prepared via Linstead macrocyclization reactions of dinitrile precusors, were subject to UV-vis titrations in the presence of inorganic ions. These polydentate macrocycles are able to bind metal ions by the peripheral ligating diazacrown or vicinal diamine entities in addition to metal ion binding within the porphyrazine (norphthalocyanine) cavity. Although 1 only weakly bound Ag(I) and Hg(II), 2 to 5 were superior polydentate ligands. Surprisingly, porphyrazine 4 was a superior ligand for binding 4 equiv of Co(II), Cu(II), Zn(II), and Cd(II) than the corresponding tetracrowned porphyrazine 2. Both 2 and 4 were excellent ligands for peripherally complexing 4 equiv of Ag(I) and Hg(II) and only for one metal, Pb(II), was the crowned system 2 superior to 4. The crowned norphthalocyanine 3 was generally inefficient in the peripheral complexation of inorganic cations, whereas 5 was superior for the peripheral binding of Co(II), Cu(II), Zn(II), Cd(II), and Hg(II) (1 equiv). Again, only with Pb(II) was the crowned system 3 a superior ligand to 5. X-ray crystallographic characterization of diazacrown 12a, porphyrazine 1 (M = Mg), and the complexes of crown 12b with Cu(BF(4))(2) and with HClO(4) are reported.
