Abstract :The synthesis of novel zinc, cobalt, indium, and metal-free phthalocyanines carrying four 3-insert ignore into journalissuearticles values(4-phenyloxy);couma- rins in the periphery/nonperiphery were prepared by cyclotetramerization of 3-[4-insert ignore into journalissuearticles values(3,4-dicyanophenyloxy);phenyl]coumarin insert ignore into journalissuearticles values(2);/3-[4-insert ignore into journalissuearticles values(2,3- dicyanophenyloxy);phenyl]coumarin insert ignore into journalissuearticles values(3);. The novel chromogenic compounds were characterized by elemental analysis, 1H NMR, mass spectra, F-IR, and UV-vis spectral data. The effects of the coumarin units on the zinc, indium, and metal-free phthalocyanine complexes insert ignore into journalissuearticles values(2a/3a, 2c/3c, 2d/3d); were also investigated.
