Metal-free and metallophthalocyanines (Zn, Co) substituted with four carboxybiphenyloxy groups on the peripheral positions were prepared from 4-(4'-carboxybiphenyloxy)phthalonitrile. Esterification of all of the biphenylcarboxylic acid groups of metal-free phthalocyanine with hexanol afforded 2,9,16,23-tetrakis(4'-carbhexyloxybiphenyloxy) phthalocyanine. These new compounds have been characterised by H-1 NMR, C-13 NMR, FT-IR, UV-Vis and mass spectroscopies. (c) 2005 Elsevier Ltd. All rights reserved.
