摘要：
A novel hyperbranched poly(aryl ether) containing azobenzene moieties (azo-HPAE) as a side chain has been synthesized and investigated on the temperature dependence of photo-induced birefringence. Typical curves of photo-induced birefringence were obtained at 25, 40, 60, 80, and 100 degrees C. The curves for buildup and decay of birefringence were fitted well with bi-exponential functions. The dependence of the fitted time constants on the temperature was also discussed.
