This invention provides bisacrylate monomers and thermoset polymers which exhibit nonlinear optical response. The polymers have utility as a transparent nonlinear optical component in optical light switch and light modulator devices.
The bisacrylate monomers correspond to the following structure:
where R is an alkyl substituent, R¹ is a divalent alkylene radical, m is an integer with a value of 0-2, n is an integer with a value of 0-1, and X is an electron-withdrawing substituent, such as -NO₂, CF₃, or -CN.
本发明提供具有非线性光学响应的双
丙烯酸酯单体和热固性聚合物。这些聚合物可用作光学光开关和光调制器设备中的透明非线性光学元件。
双
丙烯酸酯单体具有如下结构:
其中 R 是烷基取代基,R¹ 是二价亚烷基,m 是数值为 0-2 的整数,n 是数值为 0-1 的整数,X 是抽电子取代基,如 -NO₂、CF₃ 或 -CN。
