摘要
以4,4′-二氨基二苯醚、4′-甲氧基-2,4-二氨基偶氮苯及3,3′,4,4′-联苯二酸酐为反应单体,N,N-二甲基乙酰胺为溶剂合成了一种侧链含偶氮苯的高分子聚合物。并通过红外光谱(FT-IR)、紫外-可见吸收(UV-Vis)光谱、核磁(1H-NMR)、高效液相色谱(GPC)、热失重(TG)和原子力显微镜(AFM)等手段对其结构进行了表征。并以P偏振激光为干涉光源制备了可用于在同一位置点上记录多套不同信息的光栅材料。结果表明:该侧链含偶氮苯聚合物异构变化取向性好、热稳定和力学性能佳;当关闭激光光源作用后,光学记录保持不变,表现出稳定的记录效应。
Abstract
A polymer containing azobenzene side chain was synthesized used 4,4′-two amino two methoxy phenyl ether,4′-methoxy-2,4-two aminoazobenzene and 3,3′,4,4′-biphenyl dianhydride as monomers,and N,N-dimethylacetamide as solvent.The structure of polymer was characterized by infrared spectroscopy (FT-IR),ultraviolet visible absorption (UV-Vis) spectroscopy,nuclear magnetic resonance (1H-NMR),high performance liquid chromatography (GPC),thermal gravimetric (TGA) and atomic force microscopy (AFM).A kind of grating material which can be used to record multiple sets of different information at the same position was prepared by using P polarized laser as interference light source.The results showed that the polymer had a high degree of alignment,excellent thermal stability and good mechanical properties.Even when the laser light source was turned off,the optical recording remained unchanged,showing a permanent recording effect.
