Octasubstituted zinc, metal-free and magnesium complexes of phthalocyanine and tetrapyrazinoporphyrazine bearing very bulky 2,6-diphenylphenylsulfanyl substituents were synthesized. The substituents efficiently inhibited aggregation of the dyes and only monomers were detected even at a concentration of 200 μM solution in toluene. Photophys. data indicated influence of the heavy-atom effect – magnesium complexes were more fluorescent (ΦF 0.40-0.51) and zinc complexes produced stronger the singlet oxygen (ΦΔ 0.56-0.72) in both series of compounds The presence of addnl. nitrogens in tetrapyrazinoporphyrazine core made it substantially more electron deficient when compared with corresponding phthalocyanine analogs. 2,6-Diphenylphenylsulfanyl substituents also increased electron deficient character of the core and influenced the photophys. properties.
