SYNTHESIS AND CHARACTERIZATION OF CARBOXYLIC SUBSTITUTED BINUCLEAR IRON PHTHALOCYANINES

摘要

Phthalocyanine compounds is a kind of organic functional dyes, which has good optical, thermal and chemical stability. Such compounds has broad application prospects in the optical conductivity, optical storage, catalytic oxidation, and other high-tech fields. However, its solubiliey in water and organic solvents is very little, which restrict the application in many fields[1]. Carboxylic substituted phthalocyanines had not only a good solubility in water ,but excellent catalytic properties in many appilication fields. They were used as effective catalysts for oxidation of thiols and hydrosulfides by dioxygen. They have found wide application in the catalytic oxidation of mercaptans in the oil fractions. The oxidation of thiols or alkali sulfides catalyzed by metalophthalocyanine complexes is not complete, the end products being disulfides, sulfer and thiosulfates, respectively.
