The photoreactions of 9,10-dicyanoanthracene and 9-cyanoanthracene in the presence of biphenyl in acetcnitrile under oxygen atmosphere gave anthraquinone and 9(10H)anthracenone, respectively, via the reaction of the radicalanions of cyanoanthracenes with molecular dioxygen.

The thermal monomerization of 9-cyanoanthracenephotodimer (9CNAD) single crystals has been studied using differential scanning calorimetry (d.s.c.) jointly with emission spectroscopy of cleaved surfaces of partially monomerized 9CNAD single crystals. The first exothermic peak, together with the subsequent peaks, is attributed to monomer crystallization inside the photodimer host matrix and not to
