Photo-induced birefringence phenomenons of P , containing mono azobenzene chromophore and P (MMA-co-GY7), containing diazobenzene chromophore were studied by static absorption and dynamic pump-probe techniques.

研究了单偶氮苯聚合物P、双偶氮苯聚合物P（MMA-co-GY7）的紫外-可见吸收光谱、荧光光谱，并对单偶氮苯、双偶氮苯聚合物材料光谱性能的差异进行了分析；研究了偶氮苯聚合物的超快光致双折射过程，并对单偶氮苯聚合物与双偶氮苯聚合物进行了比较，分析了含双偶氮聚合物超快光致双折射过程的来源。
