Laser flash photolysis studies at 355-nm on the photoreactions of the benzophenone (BP) and N, N-dialkyl-1-naphthylamine, DANA (N, N-dimethyl-1-naphthylamine, DMNA, and N, N- diethyl-1-naphthylamine, DENA) system have been carried out with and without H2O and methanol in acetonitrile (ACN) at 295 K. In the nanosecond time scale, triplet energy transfer from triplet BP (3BP*) to DANA occurs with the efficiency ϕTET (0.74 for DMNA and 0.61 ...
