Synthesis and characterization of metal polymeric phthalocyanine from 3,3?,4,4?benzophenonetetracarboxylic dianhydride

Abstract

Metal polymeric phthalocyanines were prepared by reaction of 3,3',4,4'-benzophenonetetracarboxylic dianhydride with urea, metal salts and ammonium molybdate. The structure of these polymers was characterized by infrared spectra, visible spectra and X-ray powder diffraction. The electrical conductivity of the polymers after iodine doping was in the range of 10 -4~ l0 7 S/cm. Thermogravimetric analyses showed that these polymers have good thermal stability, and have different break mechanism under nitrogen and air condition.
