Photoluminescence Properties of Tetra- and Octa-Substituted Double Decker Lu(III) Phthalocyanines

Abstract

Fluoreccence and photoluminescence properties of tetra and octa-substituted double decker Lu(III) phthalocyanines to which imidazole groups are attached have been investigated under the same conditions. The changes in these properties were examined with increasing number of substituents. Thus, the effect of imidazole groups on the optical properties of double decker Lu(III) phthalocyanines were determined. The photoluminescence spectra of the compounds show indicating the strong π-π interaction along with electron and energy transition between the tetrapyrolic macrocycles.
