Diphenylmethane does not undergo photoaddition reactions which require initial excitation of the S0 -> S1 trasition of the arene.Reaction does, however, occur either by excitation within the charge-transfer absorption band of a ground-state complex between diphenylmethane and an addend (maleic anhydride) or by attack of a photoexcited addend (N-ethylmaleimide) onto the arene.It is considered that a mechanism for energy dissipation from S1 diphenylmethane involves through-bond interaction between the phenyl groups.
