摘　　要：3 硫代甲酰基中氮茚在哌啶催化下与碘化 1,2 二甲基喹啉盐或 1,4 二甲基喹啉盐缩合 ,以很好的收率得到一系列含中氮茚环的二甲川菁。产物的结构经元素分析、红外光谱、H核磁共振谱及质谱确证。初步测定了它们在固态下的荧光性质。结果表明 ,9种化合物发射波长在 4 0 0nm以上 。Thioformylindolizines derivatives were condensed with 1,2-dimethylquinolinium iodide or 1,4-dimethylquinolinium iodide, respectively, in the presence of piperidine to give a series of dimethine-cyanines containing indolizine ring. Their structures were comfirmed by elemental analysis, IR, 1H NMR and MS spectroscopy. The fluorescence properties of the compounds in the solid state were studied. Their luminescence properties in solid state were determined preliminary. The results showed that nine compounds 5a, 5b, 5c, 5d, 5e, and 6a, 6d, 6e and 6f exhibited emission wavelengths above 400 nm, showing potential applications in luminescent materials.
