摘要：

Using femtosecond and picosecond transient absorption measurement techniques, we have investigated the dynamic behavior of the S-2 state of diphenylbutadiyne (DPB) and its methoxy derivatives in solution. The observed much larger rate constants at room temperature and the smaller temperature-dependence of the S-2 --> S-1 internal conversion of the DPB derivatives compared to those of diphenylacetylene should be due to the large S-2-S-1 energy gap of DPBs.
