Preparation & properties research of two indium phthalocyanine materials

Abstract

Two iodo (phthalocyainato) indium complexes were synthesized and mixed with polymer solution (PMMA/chloroform) to prepare iodo (phthalocyainato) indium/PMMA compound film materials on a glass slice by the method of dipping film. Two materials have typical B-band and Q-band absorption of Phthalocyanine compounds in the UV-Vis spectrum. The reverse saturable absorption experiments show that two materials have better reverse saturable absorption properties while they have higher linear transmissivity. In addition, the highest transmitance of visible light is over 70% (tetrakis (cumylphenoxy) phthalocyainato indium/PMMA compound film material). The initial thresholds is 127.1 mJ/cm². The dynamic range is 1.43. It can be concluded that introduction of the substituted groups having bigger steric hindrance and conjugative effect in the Phthalocyanine ring may increase the reverse saturable absorption effect of the Phthalocyanine indium material.
