  Conformation and photochemical properties of 3-benzoyl-4-benzylamino-7-dimethylaminocoumarin

  摘要：

  3-Benzoyl-4-benzylamino-7-dimethylaminocoumarin was synthesized and its conformation in solid state and solution was determined. While the X-ray crystal analysis showed an aromatic pi-pi stacking interaction in the solid state, the proton NMR studies suggested the presence of an intramolecular hydrogen bonding in solution. Adjacent functional group modifications through N-methylation, reduction of carbonyl group, or replacing the coumarin moiety to dimedone, all resulted in disrupting the pi-pi stacking conformation. Upon UV irradiation, the 7-methylamino group can be oxidized by molecular oxygen to the corresponding formamide in the absence of any external photosensitizers. (C) 2013 Elsevier Ltd.
