| abstract | (57) [Summary] [Structure] An α-cyanocinnamic acid represented by the following (1) and one selected from the group consisting of two vinylpyridinecarboxylic acids represented by the following (2) and (3): It is composed of a carboxylic acid and an optically active amine salt of carboxylic acid obtained from (R)-(−)-cyclohexylethylamine represented by the following (4). [Chemical 1] [Effect] The α-cyanocinnamic acid represented by the above (1) and the two kinds of vinylpyridinecarboxylic acid represented by the above (2) and (3) are superior in transparency as compared with the conventional nonlinear optical material. , Has a relatively large non-linear susceptibility β. Further, the (R)-(-)-cyclohexylethylamine represented by the above (4) has optical activity having no symmetry center in the molecule itself. Both salts are excellent in transparency and crystallinity, and are excellent nonlinear optical materials exhibiting SHG efficiency several times that of urea. |
