Tetra[6,7]quinoxalinoporphyrazines: The effect of an additional benzene ring on photophysical and photochemical properties

Abstract

Synthetic methods for a series of zinc tetra[6,7]quinoxalinoporphyrazines were developed and their photophysical and photochemical properties were compared with tetrapyrazinoporphyrazines.
