| 摘要 |
A polymeric nomadic liquid crystal material has both a non-linear optical (NLO) response and also poling orderability, said material having semi-flexibility along the polymer backbone and stereo-regular, like-orientated incorporation in the polymer backbone of (a) a plurality of NLO elements and (b) dipolar elements, wherein the like orientation can be retained, and reversed by an applied poling field, by migration of dipole-reversing molecular defects along the backbone.
