Attempts have been made to construct optical switching molecular devices by the use of donor(D)-acceptor(A) linked compounds : (1) a passive mode as provided by photogeneration of radical pairs with a strong absorption band, and (2) an active mode due to optical second harmonic generation (SHG).The time-profile of the passive mode was decided by the decay rate of the photogenerated radical pair, which could be adjusted by the aid of external magnetic fields in combination with formation of cyclodextrin complexes of the linked compounds.Amphiphilic polypyridine ruthenium complexes, as incorporated into ultrathin polymer films, provided a novel material for SHG.The SHG intensity was reduced on irradiation of the film with UV-laser so that optical means of modulating SHG was established in this study.

已经尝试使用供体(D)-受体(A)连接的化合物来构建光开关分子器件：(1)由具有强吸收带的自由基对光产生提供的被动模式，以及(2)由光二次谐波产生（SHG）提供的主动模式。被动模式的时间分布由光生成的自由基对的衰变速率决定，并可通过外加磁场的作用和环糊精配合物的形成来调节。两亲性聚吡啶钌配合物作为超薄聚合物薄膜，为SHG提供了一种新的材料。在紫外激光照射下，薄膜的SHG强度降低，从而建立了调制SHG的光学手段。
