Lacunar derivatives of dibenzotetraaza[14]annulene: synthesis and crystal structure of new receptors produced via bis-alkylation of the macrocyclic precursor

One-flask synthesis of dibenzotetraaza[14]annulene cyclic congeners bearing buta-1,3-diyne bridges

Glaser–Hay and Glaser–Eglinton coupling conditions were applied to the direct synthesis of a cyclic strapped ligand and its corresponding dimer in 44% and 30% yields respectively.

Spin transport of dibenzotetraaza[14]annulene complexes with first row transition metals

We investigate the spin transport properties of DBTAA complexes involving first row transition metals. The results show that Fe– and Co–DBTAA exhibit perfect spin filtering effect, which is dependent on the connected position of anchoring group.
