Irradiation of naphtho[1,2-c]furazan (I) afforded two photodimers (II) and (III) accompanied by fragmentation products. The structure of the dimers was assigned on the basis of the solvent dependency for the dimerization as well as the degradation reactions of the dimers. In addition, it was suggested that the photodimerization took place via a triplet state of I.
