我们成功地合成了一些具有优异折射率性质的聚硅氧烷（SCC），它们具有垂坠的降冰片二烯（NBD）、偶氮苯（AZ）和蒽（AT）基团。对得到的聚（SCC）衍生物在紫外光照射下的光化学反应进行了研究，发现含NBD基团、AZ基团和AT基团的聚（SCC）衍生物的折射率（ΔnD’s）在光照射前后变化较大，分别在0.050 ~ 0.073、0.007 ~ 0.009和0.094 ~ 0.116之间。
We succeeded in the synthesis of certain poly(silsesquioxane)s (poly(SCC)) with excellent refractive indices properties, which have pendant norbornadiene (NBD), azobenzene (AZ), and anthracene (AT) moieties. The photochemical reactions of the obtained poly(SCC) derivatives were examined in the film state upon UV irradiation, and it was found that poly(SCC) derivatives with NBD groups, AZ groups, and AT groups had large change in values of the refractive index (ΔnD's) before and after photoirradiation which were in the range of 0.050−0.073, 0.007−0.009, and 0.094−0.116, respectively.
