Abstract

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.
