摘　　要：合成含席夫碱生色团的单体,并使之与丙烯酸酯类单体共聚制备了带有席夫碱生色团侧基的丙烯酸酯类聚合物。并利用傅立叶红外光谱、核磁共振氢谱及紫外可见光谱等测试手段,对所合成的席夫碱生色团单体及聚合物的结构进行了表征。此外,还探讨了含席夫碱生色团聚丙烯酸酯的全光开关特性及双折射性能。A novel Schiff-base monomer was synthesized, then the monomer was copolymerized with acrylate monomers to produce polyacrylates containing Schiff-base moieties in the side chain, the synthesized monomer and copolymer were characterized by means of FTIR, 1 H NMR, UV-Vis spectra and GPC. Furthermore, the all-optical switching effect and photoinduced birefringence of the Schiff-base copolymer were investigated.
