摘要
A series of polymers bearing azobenzene and carbazole groups for photorefractive purpose were prepared viapost-azo-coupling reaction.The successful reaction was identified by spectroscopic analysis and gel permeationchromatography.This approach is more facile compared with the direct polymerization of corresponding functionalmonomer.The polymers prepared have weight average molecular weight of higher than 1.5×10;and are easily soluble incommon organic solvents like chloroform and tetrahydrofuran,polymer films with high optical quality could be easilyfabricated through solution casting.Glass transition temperature (T;) of the polymers ranges from 60℃to 182℃,dependingon the alkylene spacer length between the functional side group and the polymer backbone,and the polymers are relativelystable under 300℃.
