Abstract
A novel self-arrayed hole-carryable polymer having rigid backbone of high-ordered self-orienting layer structure, i.e. polyester, polyamide or biphenyl series polyester and flexible side chain, i.e. carbazole derivatives inducing hole-carryable characteristic group and exhibiting high thermo-stability, plain processibility and high photoconductivity; and A photo-refractive material comprising the photo-refractive material, charge producer and nonlinear optical characteristic group as electro-optical material and exhibiting enhanced photoconductivity without adding plasticizer.
