Notes:
Metal-2,9,16,23-tetracarboxyphthalocyanines (1a - d) (Mt = Fe(III), Co(II), Ni(II) and Cu(II)) were transformed into their acid chlorides 2a - d which, by Friedel-Crafts reaction with the benzyl groups of poly(γ-benzyl-L-glutamate) (3), gave the polymers 4a - d. The resulting substituted poly(γ-benzyl-L-glutamate)s were found to contain about 0,2 to 2,8 mol-% of phthalocyanine rings covalently bound to the polymer main chain. Polymers 4a - d are soluble in chloroform, 1,4-dioxane, dichloroacetic acid, DMF etc. The coordination spheres around the metalphthalocyanine rings were characterized by electronic and ESR spectra. The polymers could be shown to have α-helical conformation, green or blue colored lyotropic mesophases being formed in concentrated solutions.
