was synthesized. Upon thermolysis of 1 the formation of the detectable amount of naphthacene-quinovalene (3) was observed. Singlet excited state of 7,8,9-tri-t-butyl-5,12-naphthacenequinone produced via the thermal cycloreversion of 1 is responsible for the formation of 3

5,6,7-Tri-tert-butyl-1,4-anthraquinone shows electro- and
photo-chromism, independently based on the electrochemical redox reaction
of the carbonyl groups and the χ[2 + 2]- type photo-valence
isomerization of the aromatic ring.
