9,9-Dimethyl-12-[(5-aryl-2-furyl) (or 5-aryl-2-thienyl, or 5-aryl-1-methyl-1H-pyrrolyl)]-7,8,9,10,11,12-hexahydrobenzo[a]acridin-11-ones were synthesized, and their absorption and luminescence spectrum characteristics in ethanol at room temperature and at 77 K were studied. The spectra suggest the existence of these compounds in a liquid solution as mixtures of conformers, each of which is characterized by its own absorption and fluorescence spectra.
