摘要
本文以五个酯酮型双冠醚为配体，分别与苦味酸钠、苦味酸钾和苦味酸铷反应，制备了十五种双冠醚配合物，并用元素分析、红外光谱、紫外光谱和热重分析进行了表征．结果表明，双冠醚与钠盐以１∶１（冠醚单元∶金属离子）形式配位，而与钾和铷盐则以２∶１形式配位．
Fifteen kinds of biscrown ethers complexes are prepared by the reaction of ester ketonic type biscrown ethers with alkali metal picrates, and characterized by elemental analysis, IR spectra, UV spectra, and thermogravimetry. The result shows that the five biscrown ethers can form 1∶1 (crown unit: metal iron) type complexes with sodium picrate, and 2∶1 type complexes with potassium or rubidium picrate.
