摘要: 合成了新型类芪生色团,并通过酰氯化反应制得含芪生色团的单体,将所合成的单体与丙烯酸酯类单体进行自由基共聚制得以类芪生色团为侧基的聚合物.利用核磁共振波谱( HNMR)、红外光谱(FTrIR)和紫外吸收光谱(uV.Vis),对所合成的单体及聚合物进行了结构表征,并探讨了所制备聚合物的全光开关效应.研究结果表明:在激发光的照射下,通过聚合物中类芪基团的反一顺一反异构循环,在聚合物材料中可形成光致各向异性;所制得的聚合物在较低的驱动光功率(8mW)下具有良好的全光开关效应.

Abstract:

First,a new pseudo-stilbene chromophore was synthesized and the corresponding monomer was obtained by means of acylation reaction.Next,a kind of polymer with pseudo-stilbene chromophores as the side groups was prepared by the radical polymerization of the above-mentioned monomer and acrylate monomer.Then,the chromo-phore monomer and the coresponding polymer were structurally characterized using HNMR,FTIR and UV-Vis spectroscopy.Finally,the all-optical switching effect of the polymer was experimentally investigated.The results indicate that,with the iradiation of pump beam,the repetition of trans-cis-trans photoisomerization of pseudo-stil-bene groups leads to a photoinduced anisotropy in the polymer,and that the all-optical switching effect can be realized with a low optical driving power of 8 mW .

Key words: chromophore, pseudo-stilbene, all-optical switching effect, photoisotropy
