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
