Abstract
In search for future good adsorbents for CO2 capture, a nitrogen-rich triazole-type Metal-Organic Framework (MOF) is proposed based on the rational design and theoretical molecular simulations. The structure of the proposed MOF, named Zinc Triazolate based Framework (ZTF), is obtained by replacing the amine-organic linker of MAF-66 by a triazole, and its structural parameters are deduced. We used grand-canonical Monte Carlo (GCMC) simulations based on generic classical force fields to correctly predict the adsorption isotherms of CO2 and H2O. For water adsorption in MAF-66 and ZTF, simulations revealed that the strong hydrogen bonding interactions of water with the N atoms of triazole rings of the frameworks are the main driving forces for the high adsorption uptake of water. We also show that the proposed ZTF porous material exhibits exceptional high CO2 uptake capacity at low pressure, better than MAF-66. Moreover, the nature of the interactions between CO2 and the MAF-66 and ZTF surface cavities was examined at the microscopic level. Computations show that the interactions occur at two different sites, consisting of Lewis acid-Lewis base interactions and hydrogen bonding, together with obvious electrostatic interactions. In addition, we investigated the influence of the presence of H2O molecules on the CO2 adsorption on the ZTF MOF. GCMC simulations reveal that the addition of H2O molecules leads to an enhancement of the CO2 adsorption at very low pressures but a reduction of this CO2 adsorption at higher pressures.

Abstract
The present work carried out a theoretical study of the electronic structures, absorption spectra, and photovoltaic performance of two series of transition metal-phthalocyanine derived from nonperipheral electron-donating substituents, either (2-phenyl) phenoxy(M-PC1) or quinoleinoxy(M-PC2). The DFT and TD-DFT were employed for this study. The effect of modifying the central metal atoms and the substitution on cell performance were investigated in terms of polarizability (α), hyper-polarizability (β), chemical potential (μ), chemical hardness (η), electrophilicity power (ω), FMOs, energy gaps, UV/vis absorption spectra and injected driving force (ΔGinject), light harvesting efficiencies (LHE), total reorganization energy (λtot), open circuit photovoltage (Voc), and life time of the excited state (τ). The results obtained by using these parameters showed that the replacement of (2-phenyl) phenoxy by a proposed substituent such as quinoleinoxy would increase the hyper-polarizability, light harvesting efficiency, and open circuit photovoltage, while on the other hand the reorganization energy and the injection driving force are decreased. Modifying central metal atoms, such as Zn, Cd, Pd, and Pt, exhibited good performance in terms of the driving force of electron injection, charge transfer characteristics, and dye reorganization as compared with the Cu reference dye. The findings provided a useful prediction and perspective for the promising future for high-efficiency dye-sensitized solar cells (DSSCs) with dyes based on phthalocyanine.

Abstract
At present, we investigate the structures, the stability, the bonding and the spectroscopy of the Zn2+-triazole complexes (Zn2+-Tz), which are subunits of triazolate based porous materials and Zn-enzymes. This theoretical work is performed using ab initio methods and density functional theory (DFT) where dispersion correction is included. Through these benchmarks, we establish the ability and reliability of M05-2X+D3 and PBE0+D3 functionals for the correct description of Zn2+-Tz bond since these DFTs lead to close agreement with post Hartree-Fock methods. Therefore, M05-2X+D3 and PBE0+D3 functionals are recommended for the characterization of larger organometallic complexes formed by Zn and N-rich linkers. For Zn2+-Tz, we found two stable σ-type complexes: (i) a planar structure where Zn2+ links to unprotonated nitrogen and (ii) an out-of-plane cluster where carbon interacts with Zn2+. The most stable isomers consist on a coordinated covalent bond between the lone pair of unprotonated nitrogen and the vacant 4s orbital of Zn2+. The roles of covalent interactions within these complexes are discussed after vibrational, NBO, NPA charges and orbital analyses. The bonding is dominated by charge transfer from Zn2+ to Tz and intramolecular charge transfer, which plays a vital role for the catalytic activity of these complexes. These findings are important to understand, at the microscopic level, the structure and the bonding within triazolate based macromolecular porous materials and Zn-enzymes.
