PURPOSE:To obtain a material having excellent moldability and an optical nonlinear effect of high efficiency by bonding a compd. having a prescribed compsn. as a optical nonlinear side chain to a thermotropic liquid crystal high polymer. CONSTITUTION:This material is obtd. by bonding the compd. expressed by the formula I as the optical nonlinear side chain to the thermotropic liquid crystal high polymer. In this formula I, (pi1), (pi2): a cyclic compd. of a pi electron conjugation system and may be of the structures equal to or different from each other, X, Y: C, H, N or N O, R1, R2: functional groups. The more specific example of the compd. having such optical nonlinear effect is like, for example, the formula II, the formula III. This material has high mechanical strength, the excellent moldability and workability and the large tertiary nonlinear optical effect and is usable for all kinds of materials for optical information processing. |
