The synthesis of symmetrically substituted novel metallophthalocyanines (M=Zn(II), Cu(II), Co(II)) bearing four 3,5-bis(trifluoromethyl)phenylethynyl moieties was achieved by following the well-known palladium-catalyzed cross-coupling methodology starting from the corresponding tetraiodo-substituted metal phthalocyanines. Alkynyl substituted phthalocyanines (Pc) are scarcely soluble in organic solvents;...
