The compound 5 of 2-furaldehyde-indolizine was synthesized. Its structure was characterized by using IR, UV and t H NMR. The fluorescent and the influence of different transitional metal ions such as Co2＋ ,Ca2＋ , Zn2＋ ,Cu2＋,K＋ ,Ni2＋ ,Mn2＋ ,Pb2＋ on thiscompound were studied systematically. The results showed this compound exhibited a highly selective fluorescence quenching effect by Pb2＋ ions, while other metal ions almost no quenching happened. The UV absorption spectra increased with the addition of Pb2＋ into the solution of 2-fural- dehyde-indolizine suggesting that chemical reaction occurred between the Pb2＋ and this compound. This com- pound is promising to be the probe for the Pb2＋.
