The series of linear-shaped phenylacetylenyl- and (phenylacetylenyl) phenylacetylenyl-substituted aromatic enediynes 1-3 were synthesized as pure trans and cis isomers and their photochemistry explored. With expansion of the π-electron system, the absorpt

Pyrolysis of 1,6-diphenylhexa-1,5-diyne-cis-3-ene at 800-1000 °C leads to a mixture of 1- and 2-phenylbiphenylene, along with triphenylene. Formation of the two biphenylenes is taken as strong evidence of the rearrangement of a p-benzyne into a m-benzyne through a shift of one of the phenyl groups. Copyright

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.
