Abstract

The UV and visible absorption spectra of 14 quinoline analogs of chalcone are measured in carbon tetrachloride and alcohol. Replacement of phenyl or pyridyl-2 by quinolyl-2 has a bathochromic effect. Comparison of the spectral characteristics of the compounds investigated shows that in the systems considered, quinolyl-2 is more electron-accepting than naphthyl-2, phenyl, and pyridyl-2. Introduction of electron-donor substituents (methoxy, amino, and dimethylamino groups) into the aromatic ring of the quinoline chalcone gives rise to a significantly larger bathochromic effect when that ring is remote from the carbonyl group.
