Azaphthalocyanines containing pyrazine rings with focus on the alkylheteroatom, aryl and heteroaryl substitution and properties important in photodynamic therapy

Abstract

We summarized recent knowledge about the syntheses, UV-vis absorption properties, aggregation, protonation and deprotonation of macrocycle and singlet oxygen and fluorescence quantum yields in the group of azaphthalocyanines bearing pyrazine rings in their conjugated system
