An optical article is disclosed containing, for the transmission of electromagnetic radiation, a medium exhibiting a second order polarization susceptibility greater than 10⁻⁹ electrostatic units comprised of polar aligned noncentrosymmetric molecular dipoles having an electron donor moiety linked through a conjugated π bonding system to an electron acceptor moiety to permit oscillation of the molecular dipole between a ground state exhibiting a first dipole moment and an excited state exhibiting a differing dipole moment. The molecular dipoles are held in polar alignment by a crosslinked polymeric binder.
本发明公开了一种用于传输电磁辐射的光学产品,该产品含有一种介质,该介质显示出大于 10-𠞙 静电单位的二阶偏振电感,该介质由极性排列的非中心对称分子偶极子组成,该分子偶极子具有一个电子供体分子,该电子供体分子通过共轭 π 键系统与一个电子受体分子相连,从而允许分子偶极子在显示第一偶极矩的基态和显示不同偶极矩的激发态之间摆动。分子偶极子通过交联聚合物粘合剂保持极性排列。
