Synthesis and Optical Properties of Copolymeres Bisphenol A and D-Π-A Chromophores

Abstract

A series of optical polymeres were prepared by a Mitsunobu reaction from the correspondingN,N-dihydroxyethyl D-π-A chromophores and bisphenol A, which is new main-chain copolymeres with good solubility in ordinary organic solvents. The linear and nonlinear optical (NLO) properties were investigated by UV spectra and NLO measurements. The results indicate that the films of copolymeres exhibit a higher macroscopic second nonlinear optical coefficient, thermal stability and good optical transparency.
