摘要：

Decarbonylation of diphenylcyclopropenone (DPCP) in several solvents has been investigated by using picosecond transient absorption spectrum measurement techniques. We have confirmed that the electronically excited states of diphenylacetylene (DPAC) are formed immediately after excitation at the second absorption band of DPCP and that the yields of the excited states of DPAC depend on the excitation wavelength.
