【摘要】 合成了由2-呋喃甲醛修饰的中氮茚类化合物(5),研究了多种金属离子对其荧光光谱的影响。结果表明其对Pb2+具有良好的荧光识别性。紫外光谱则表明二者之间发生了明显的化学反应。

【Abstract】 The compound 5 of 2-furaldehyde-indolizine was synthesized.Its structure was characterized by using IR,UV and 1H 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-furaldehyde-indolizine suggesting that chemical reaction occurred between the Pb2+ and this compound.This compound is promising to be the probe for the Pb2+.
