摘要：

9,10-Dicyanoanthracene (DCA) and 2,4,6-triphenylpyrylium tetrafluoroborate (TPP+) were used to sensitize the isomerization of cis-stilbene in sodium dodecylsulphate (SDS) micellar solutions with steady state and pulsed laser excitation. During TPP+ triplet sensitization, the isomerization quantum yield was nearly four times higher than that in homogeneous solution; however, the DCA excited singlet was not effective in isomerization.
