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 a linear polymer containing 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 linear polymer is a condensation polymer including in its backbone a plurality of molecular dipoles including sulfonyl electron acceptor moieties sequentially arranged to reinforce electron displacement along the polymer backbone.
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,该介质由线性聚合物组成,该线性聚合物含有极性排列的非中心对称分子偶极子,该分子偶极子具有电子供体分子,该电子供体分子通过共轭 π 键系统与电子受体分子相连,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。线性聚合物是一种缩聚聚合物,在其骨架中包含多个分子偶极,其中包括依次排列的磺酰电子受体分子,以加强沿聚合物骨架的电子位移。
