The direct, triplet-sensitized, and low-temperature photolyses of 2,2′-diazidobiphenyl have been studied. The direct irradiation afforded 4-azidocarbazole, and the triplet sensitization resulted in the predominant formation of the azo dimer, accompanied by a low yield of benzo[<I>c</I>]cinnoline. The photolysis in a rigid matrix at 77 K afforded benzo[<I>c</I>]cinnoline quantitatively. The mechanism for its preferential formation in low-temperature matrix photolysis is discussed, and we propose a biphotonic process involving a dinitrene <I>via</I> a mononitrene.
