| Abstract: | 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.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 7, 2005, pp. 1221–1224.Original Russian Text Copyright © 2005 by Korzhenevskii, Markova, Efimova, Koifman. |
