Abstract
The synthesis of two asymmetrical zinc (II) phthalocyanines (ZnPcs) containing 4-carboxyphenyl and 3-thienyl or 5?-hexyl-2,2?-bithiophene substituent was described. These Zinc Phthalocyanines were synthesized by a statistical condensation reaction between two different phthalonitriles. Each of the phthalonitrile precursors was accomplished by the Suzuki-Miyaura cross-coupling reactions with the aryliodide and corresponding boronic acids. The ZnPc dyes were characterized by MALDI-MS, FT-IR, 1H NMR, UV
