The photochemistry of 11,12-bis(aminomethyl)-9,10-dihydro-9,10-ethenoanthracene (4) was investigated in solution and in the solid state. Direct irradiation of 4 gave the singlet state photoproduct 5, whereas the triplet derived photoproduct could only be obtained by irradiating the bis(hydrochloride) salt of 4 in the presence of xanthen-9-one to give semibull-valene 6-(HCl)(2). Solid state photolysis of 4 resulted in the formation of the pyrrole derivative 7, which is likely due to steric interactions in the solid state.
