Synthesis of Dimethine-cyanines Containing Indolizine Ring
Abstract:
3-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.
