摘　　要：以染料掺杂物的作用为侧重点,讨论了向列相液晶的光学重新取向问题,介绍了一个能说明吸收液晶中光学矩增强的分子模型,分析了宾-主系统中偶氮染料光致异构化对光学重新取向的影响。This paper reviews the progress in the photo-induced molecular reorientation in dye-doped nema- tic liquid crystals, presents the current experimental background and theoretical explanations perti- nent to the optical reorientation in doped liquid crystals, and discusses the effects of the photoisome- rization on the photo-induced molecular reorientation in the azo-dye doped liquid crystals.
