An organic guest compound having both an electron attractive group and an electron donative group is blended with a host polymer selected from a lactone polymer and a copolymer nylon to form a solid solution. The solid solution shows good mechanical strength and processability and may be suitably formed into a nonlinear optical device. Even if the guest compound is a compound, such as p-nitroaniline, which has a large non-linearity but is by itself liable to form a centrosymmetrical crystal thus showing no SHG activity, the solid solution obtained by blending it with the host polymer can show a uniform and large SHG activity.
将同时具有引电子基团和供电子基团的有机客体化合物与选自内酯聚合物和共聚尼龙的主聚合物混合,形成固溶体。该固溶体具有良好的机械强度和加工性能,可适当地制成非线性光学器件。即使客体化合物是一种化合物,例如对
硝基苯胺,它具有很大的非线性,但其本身容易形成中心对称晶体,因而不显示 S
HG 活性,但将其与主聚合物混合后得到的固溶体可以显示出均匀而大的 S
HG 活性。
