Three representative diphenyltriafulvenes, 4,4'-dicy.mo-1 ,2-diphenyltriafulvenc (I), hexaphenyltriapentafulvalene (II) and IO-(3,3diphenylcyclopropenyliden)-anthrone (III) have been investigated. On excitation. the dipole moment of I decreases and reverses sign, i.e., from a value of 7.9 D in the g

The room-temperature lifetimes of ring-substituted excited diphenylmethyl radicals have been shown to correlate well with the energy gap between the fluorescent lowest excited doublet and the ground state. Attempts to correlate the lifetimes with Hammett constants were unsuccessful.
