Synthesis and Photoluminescence Properties of Saccharide Conjugated Copper Phthalocyanine via Click Reaction

Abstract

This research concentrates on the preparation, characterization, and photoluminescence properties of saccharide conjugated copper phthalocyanine (CuPc) and its metal-free precursor (H₂Pc). The H₂Pc ligand gave intense emissions (where λ_max = 701 nm) upon irradiation by visible light. The photoluminescence quantum yields and long excited-state lifetimes of these compounds were measured. The H₂Pc has photoluminescence quantum yield of 0.42 and long excited-state lifetime of 3.89 ns. The photoluminescence intensities and quantum yields of H₂Pc decreased dramatically upon complexation with copper metal and derivatization with saccharide groups.
