Synthesis, characterization, and determination of photophysicochemical properties of peripheral and nonperipheral tetra-7-oxy-3,4-dimethylcoumarin substituted zinc, indium phthalocyanines

Abstract

The photochemical and photophysical properties of peripheral and nonperipheral zinc and indium phthalocyanines containing 7-oxy-3,4-dimethylcoumarin synthesized were investigated in this study. 7-Hydroxy-3,4-dimethylcoumarin (1) was synthesized via Pechma
