摘要：

Both cis- and trans-1,2-bis(phenylethynyl)ethenes (1) gave fluorescence emission with considerably high quantum yield and intersystem crossing to the triplet state which underwent cis-trans isomerization. On the basis of the results, a novel potential energy surface of isomerization of 1 was proposed.
