摘要：

The quantum yield of singlet oxygen (O-1(2)) production from 9,10-dicyanoanthracene (DCA) in the presence of trans-stilbene (TS) was determined by measurement of its 1268-nm emission. The formation of O-1(2) is quenched by TS in acetonitrile but enhanced in benzene. Exciplex emission is observed in both solvents. These observations suggest that exciplex formation in benzene leads to enhanced intersystem crossing in DCA, but that ion-pair separation is too rapid to allow this process in acetonitrile.
