A fully rigid tetrakisimidazolium macrocycle was synthesized in good yield for the first time through direct [2+2] cyclization. The structure was characterized by NMRs, MS and X-ray diffraction analysis. This cationic, fluorescent macrocycle with four hydrogen bond donors pointing inward the large and rigid cavity may serve as an anion receptor, a fluorescent material and a building block for supramolecular assembly.
通过直接[2+2]环化,首次合成了一个完全刚性的四咪唑大环,收率很高。通过核磁共振、质谱和 X 射线衍射分析对其结构进行了表征。这种阳离子荧光大环具有四个氢键供体,指向内部的大而硬的空腔,可用作阴离子受体、荧光材料和超分子组装的构件。
