    摘要: The present invention relates to methods for accelerating the trans-cis isomerization of 1,2-diphenylethylene analogues by using photocatalyst. According to this invention, in the presence of polypyridyl platinum(II) complex with catalytic dosage, a solution containing trans-1,2-diphenylethylene analogues or mixture of cis- and trans-1,2-diphenylethylene analogues is irradiated by visible light to prepare product of cis-1,2-diphenylethylene analogues or product predominantly being cis-1,2-diphenylethylene analogues under inert gas atmosphere. This method has the advantages of fast reaction, high performance, easy separation of reaction system and recycle of the polypyridyl platinum (II) complexes.
