• 1-Benzoyl-2-phenylacetylene (BPA) is prepared.
• The triplet energy of BPA is found to be 65 kcal mol-1.
• The excited state character of BPA is similar to that of benzophenone.
• The absorption spectra of triplet BPA and the ketyl radical are identified.
1-Benzoyl-2-phenylacetylene (BPA) having a moderate triplet energy (65 kcal mol−1) was prepared, and steady state and laser photolysis techniques were conducted to characterize the photochemical features of the triplet state and the BPA ketyl radical that was formed via H-abstraction of the triplet n,π* from alcohol and phenol. The photophysical and photochemical properties of BPA similar to those of benzophenone may encourage photochemists to use it as an n, π* triplet sensitizer scheduled for triplet-energy-tuned experiments upon laser flash photolysis in solution.
