在硫酸铜催化下,通过3-乙酰乙酰基香豆素与5-氨基吡唑的加成环化反应合成了一系列官能团化的香豆素并[4,3-d]吡唑并[3,4-b]吡啶衍生物3a~3h.合成得到的部分化合物具有很高的荧光量子产率.利用荧光光谱考察了其与Ag~+、Cr~(3+)、Co~(2+)、Cu~(2+)、Pb~(2+)、Sn~(4+)、Fe~(3+)、Zn~(2+)等金属离子的作用,结果表明化合物3a和3b对Zn~(2+)具有很好的选择性识别能力. A series of functionalized coumarino [4,3-d] pyrazolo [3] were synthesized by the addition reaction of 3-acetoacetylcoumarin and 5-aminopyrazole under copper sulfate catalysis , 4-b] pyridine derivatives 3a ~ 3h. Some of the compounds synthesized have high fluorescence quantum yield.Using fluorescence spectroscopy to investigate the interaction between these compounds and Ag ~ +, Cr ~ (3 +), Co ~ Cu 2+, Pb 2+, Sn 4+, Fe 3+, Zn 2+ and other metal ions. The results show that compounds 3a and 3b have good effect on Zn ~ (2+) has a very good selectivity of recognition.
