Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Dalton Transactions called Systematic investigation of phthalocyanines, naphthalocyanines, and their aza-analogues. Effect of the isosteric aza-replacement in the core, Author is Novakova, Veronika; Reimerova, Petra; Svec, Jan; Suchan, Daniel; Miletin, Miroslav; Rhoda, Hannah M.; Nemykin, Victor N.; Zimcik, Petr, which mentions a compound: 56413-95-7, SMILESS is N#CC1=NC(Cl)=C(Cl)N=C1C#N, Molecular C6Cl2N4, Category: chiral-oxygen-ligands.
Zinc complexes of phthalocyanine, naphthalocyanine and their aza-analogs with alkylsulfanyl substituents were synthesized and characterized by UV-visible and MCD spectroscopy, and their redox properties were investigated using CV, DPV, and SWV approaches as well as spectroelectrochem. methods. Aggregation, photostability, singlet oxygen production, and fluorescence quantum yields of the target complexes were studied as a function of the stepwise substitution of the aromatic C-H fragments by nitrogen atoms. The electronic structure and vertical excitation energies of the target compounds were probed by DFT-PCM and TDDFT-PCM approaches. Introduction of addnl. nitrogens into the structure leads to a hypsochromic shift of the Q-band and makes the macrocycle strongly electron deficient and more photostable. The impact on the photophysics is limited. The relations between the type of macrocycle and the studied properties were defined.
