Abstract The condensation of substituted diiminoisoindolines with alkyl-substituted 1, 3, 3- trichloroisoindolines results in the formation of the highly soluble metal-free phthalocyanines 9, 15. By the same methodology, metal-containing phthalocyanines such as 16, 18 are accessible from suitable metal salts. The precursors 24 and26 were obtained from the phthalocyanine 9 and tetracyclone. The generation of the phthalocyanines 23 and 25 ...
