摘要/Abstract

摘要： 介绍了有机化学新领域─固相光化学研究的重要意义和特点。通过色氨酸类、核酸碱基衍生物同稠环化合物异种分子间固态光化学的研究,揭示出这种反应的高选择性和专一性,对反应历程也进行了初步研究,为合成化学提供了新方法。利用晶格控制物质,使不易进行光化学反应的物质可顺利地定向进行光化学反应,亦可直接用于合成D或L手性化合物,省去拆分。对C-T络合物(电荷转移)和分子化合物的固态光化学也进行了研究。

关键词: 固态光化学, 混晶, 微环境影响, 异种分子

Abstract: In this paper, a new field of organic photochemical reaction in solid state with an important significance and characteristics is reviewed;We have investigated bimolecular photoreactions between two different organic molecules, such as a series of tryptophans and the nucleic acid beses with fused polycyclic aromatic hydrocarbons.The result shows that the reactions exhibit a high stereo-and regio-selectivity.This is a new effective synthetic method.The reaction mechnism was also postulated.By using a crystal lattice-controlling substance a series of compounds for which the photoreaction can not take place may undergo the regio-and stereo-selectivity photoreaction.The method can be employed to synthesize optical active Dor Lcompounds which need not resolution.The charge transfer(C-T)complexes and molecular compounds were also investigated in solid state photoreaction.

Key words: Solid state photochemistry, Mixed crystal, Micro-environmental influence, Two different molecules
