摘要：

The efficiency of unimolecular cis → trans conversion of radical cations of stilbene derivatives depends on the substituents on the phenyl rings, as observed by transient spectroscopy and on steady irradiation. Among the stilbenes employed, the radical cations of cis-4,4′-dibromo- and cis-4,4′-dimethylstilbene were, when generated by secondary electron transfer, converted unimolecularly to those of the corresponding trans-stilbenes in high quantum yields at ambient temperature. © 1990.
