The effect of linear benzannelation on the spectral appearance of peripheral octaaza substitution in phthalocyanine molecules in going from tetrapyrazinoporphyrazines to tetra-2,3-quinoxalinoporphyrazines in protic and aprotic solvents, such as H2SO4, high-percentage oleum, DMSO, and DMF) is intricate and does not allow the contribution of such ligand modification to be assigned exclusively to decreased electron-acceptor power of its periphery.
