摘要：

N2-laser flash photolysis measurements of poly (N-vinylcarbazole) (PVCz) and N-isopropylcarbazole (NIPC) with p-dicyanobenzene (DCNB)_in dimethylformide (DMF) show an excitation intensity dependent quantum yield for for ion-radical production. The transient absorbance associated with the ion radical species together with light intensity dependent fluorescence decay curves demonstrate that excitation annihilation processes can compete effectively with ion-radical formation at high excitation intensities in this polymer. © 1979.
