摘要：

3-Styrylperylene undergoes one-way cis-->trans photoisomerization in the triplet state through a quantum chain process. The conversion of cis to trans triplet state was directly observed by laser spectroscopy to proceed with an activation energy of 6.6 kcal mol(-1). This finding clearly demonstrates that in the series of styrylarenes, ArCH=CHPh, lowering of the tripler excitation energy of Ar group alters the mode of isomerization from two-way to one-way.
