The synthesis and characterization of new functionalized phthalocyanines (Pcs) directly condensed with benzothiophene moieties are described. These Pcs are formed from planar heterocycles, and one of the compounds incorporates a benzothiophene unit substituted with two chlorine atoms. The dicyano precursor of the Pc was synthesized via a radical coupling reaction between phenyl radicals and a thiophenyl moiety. The phthalocyanine ring was successfully formed, as confirmed by UV?vis absorption spectroscopy and MALDI?MS analysis. The design strategy and the optical properties of these Pcs contribute to the advancement of phthalocyanine-based photodynamic therapy (PDT) for cancer treatment.
