A series of indolizines were synthesized.The fluorescence spectra and fluorescence quantum yields of the compounds 3a~3k, 4a~4b and 5~6 were examined.It was found that the quantum yields increased if the cyano group was introduced into the indolizines, while the presence of carbonyl groups as substituents of indolizines resulted in fluorescence quenching.The indolizines 3a~3b and 3g~3i with high fluorescence quantum yields are shown to be useful fluorophores to the construction of probe compounds.

Key words: indolizine,fluorescence spectrum,fluorescence quantum yield
