【 摘 要 】

The Friedländer reactions of acetylbenzenes and 2-acetylpyridine with 3-aminonaphthalene-2-carbaldehyde afforded the corresponding 2-phenylbenzo[g]quinoline and 2-(pyrid-2-yl)benzo[g]quinoline, respectively. The same reactions of 3-aminonaphthalene-2-carbaldehyde with 1,2-, 1,3-, 1,4-di- and 1,3,5-triacetylbenzenes, however, afforded a series of corresponding (benzo[g]quinolin-2-yl)benzenes as new N,C-bidentate and unexpected benzo[g]quinoline. Crystallinity, thermal properties, absorption and emission spectral properties of the products were studied.
