摘要： The invention relates to an optically non-linear active waveguiding material comprising an optically transparent polymer and a non-linear optical dopant comprising more than one donor-.pi.-acceptor unit.Dopants comprising more than one donor-.pi.-acceptor unit, especially dopants in which the donor-.pi.-acceptor units are positioned in a cyclic group, have a high hyperpolarizability and a charge-transfer absorption band wavelength which is about the same as that of dopants with only one donor-.pi.-acceptor unit.Especially suitable dopants for use are calix(4)arenes. These are provided with acceptor groups at the upper rim and with donor groups at the lower rim. In addition to having excellent hyperpolarizability, these compounds were found to be readily soluble in host polymers, such as polymethylene (meth) acrylate and polystyrene. Because of their charge-transfer absorption band at a low wavelength, optically non-linear active waveguiding structures containing such dopants are suitable for use as frequency doublers.The invention further relates to hitherto undisclosed calix(4)arenes functionalized with nitrostilbene groups, cyanostilbene groups, sulfor stilbene groups, sulfonate stilbene groups, azobenzenes or benzylidene aniline compounds.
摘要翻译：本发明涉及一种光学非线性有源波导材料，其包括光学透明的聚合物和包含多于一个供体-β-受体单元的非线性光学掺杂剂。包含多于一个供体-π-受体单元的掺杂剂，特别是其中供体-π-受体单元位于环状基团中的掺杂剂具有高超极化性和电荷转移吸收带波长，其与只有一个供体pi受体单位的掺杂剂。特别适合使用的掺杂剂是杯形（4）芳纶。这些在上边缘设置有受体组，在下边缘具有供体组。除了具有优异的超极化性之外，发现这些化合物容易溶于主体聚合物，例如聚亚甲基（甲基）丙烯酸酯和聚苯乙烯。由于其在低波长下的电荷转移吸收带，包含这种掺杂剂的光学非线性有源波导结构适合用作倍频器。本发明还涉及用硝基二苯乙烯基官能化的迄今为止未公开的杯（4）芳烃，氰基茋基，磺基二苯乙烯基，磺酸二苯乙烯基，偶氮苯或亚苄基苯胺化合物。
