Synthesis and characterization of a series of new 2-unsubstituted 3-(2-benzylbenzoyl)quinolin-4(1H)-ones is described. In addition to their potential biological activity, these compounds exhibit photoreversible photochromic properties in anaerobic conditions. Using the 1 and 2D NMR techniques we demonstrated that the coloration occurred owing to the formation of fluorescent 5a,6-dihydrobenzo[b]acridin-(5H)-ones
