Fluorescence Properties of the schiff-base polymers

摘要

A series of 5 conjugated aromatic polymines (Schiff-base polymers), containing -C=N- linkages in the backbone and various side-group substitutions, has been synthesized, characterized, and used to investigate the effects of molecular structure on the electronic structure and properties of these polymers. In this paper we report the photophysical behaviour of the Schiff-base polymers and their diluted solutions in DMA. The fluorescence excitation and emission spectra of these compounds were measured. These compounds show no evidence of excimer formation under these conditions and their fluorescence exhibits in solid state and in solution first-order decay behaviour.
