(57) [Summary] [Structure] Consists of structural units represented by the following general formulas (I) and (II), containing 5 to 100 mol% of the unit of the formula (I), An organic nonlinear optical material having a molecular weight of 10,000 to 2,000,000. [Chemical formula 23] [Chemical formula 24] [Effect] Since it has a large non-linear optical effect and excellent moldability, it can be widely applied in the field of optical processing. |
