Synthesis and properties of azaphthalocyanines with 1,2,3,4-tetrahydropyrazino[2,3-b]pyrazine moiety

Abstract

Several new azaphthalocyanines were prepared and their singlet oxygen production, fuorescence and aggregation properties were studied. Excited states of the compounds are mostly quenched by intramolecular charge transfer.
