for a series of zinc tetra[6,7]quinoxalino-porphyrazines (6,7-TQP) with peripheral chains connected through the S, O and N heteroatoms as well as through the C―C bond were developed. Photophysical and photochemicalproperties of 6,7-TQP were compared with tetrapyrazino-porphyrazines (TPP) bearing the same peripheral substituents to disclose the effect of insertion of a benzenering between the pyrazine
