The synthesis and characterisation of a rigid nanoscale macrocycle with two exotopic phenanthroline binding sites is reported. Scanning tunnelling microscopy (STM) at the solid-liquid interface reveals the formation of highly ordered monolayers of macrocycles with dimensions that are in good agreement with the calculated structure. Using the HETPHEN concept several bisheteroleptic coordination complexes
有两个exotopic菲咯啉结合位点的刚性纳米级大环的合成和表征的报告。固液界面的扫描隧道显微镜(STM)揭示了大环的高度有序的单分子层的形成,其尺寸与所计算的结构非常吻合。使用HETPHEN概念,在铜(I)离子存在的情况下,制备了几种与其他菲咯啉的抗细菌配位配合物和一个纳米级篮子组件。NMR光谱,质谱数据和元素分析指出了溶液中篮筐组件的三种不同异构体。准备了一个银筐,可以很容易地将其转换成铜类似物。电喷雾电离(ESI)-MS和分光光度法研究为组装过程提供了更多的机械原理。
