Provided are: a prepolymer which is capable of forming a non-linear optical material that has excellent non-linear optical effect, heat resistance, withstand voltage and transparency; a curable material which contains the prepolymer; a coating composition which contains the curable material and a solvent; a non-linear optical material which is obtained by curing the curable material; an optical waveguide which uses the non-linear optical material; and a light control device which is provided with the optical waveguide. The present invention uses a prepolymer having a crosslinkable functional group, which is obtained by reacting one or more compounds (X) that are selected from the group consisting of compounds (X1), compounds (X2) and compounds (X3), a compound (Y) that is represented by formula (Y), a compound (Z) that has three or more phenolic hydroxyl groups, and an organic compound (B) that exerts a non-linear optical effect and has a reactive group.
本发明提供了:一种能够形成非线性光学材料的预聚物,该材料具有优异的非线性光学效果、耐热性、耐电压性和透明度;一种包含该预聚物的可固化材料;一种包含该可固化材料和溶剂的涂层组合物;一种通过固化该可固化材料而获得的非线性光学材料;一种使用该非线性光学材料的光波导;以及一种配备该光波导的光控制装置。本发明使用了一种具有可交联官能团的预聚物,该预聚物是通过将一种或多种选自化合物(X1)、化合物(X2)和化合物(X3)组成的组的化合物(X)、由式(Y)表示的化合物(Y)、具有三个或多个酚羟基的化合物(Z)和具有非线性光学效应并具有活性基团的有机化合物(B)反应而得到的。
