Аннотация:
The conformational effects in the ground and excited states were studied for N-substituted 2-(2-aminophenyl)-4H-3,1-benzoxazin-4-ones. The structural relaxation of the excited ESIPT product was revealed, which results in the formation of a nonplanar conformer undergoing efficient nonradiative deactivation. The aggregation of fluorophore molecules was observed in saturated hydrocarbons at low temperatures for N-substituted 2-(2-aminophenyl)-4H-3,1-benzoxazin-4-ones with the amido carbonyl group. Excited-state intramolecular proton transfer was not observed in this associate, and the fluorophore molecules were shown to occur in the nonplanar conformation, in which there is no intramolecular hydrogen bonding. © 2010 Pleiades Publishing, Ltd.
