A mixed halogen- and hydrogen-bonding hetero-[2]catenane has been synthesised via an anion templated Grubbs' II-catalysed RCM clipping mechanical bond forming methodology. 1H NMR spectroscopy and fluorescence titration experiments demonstrated the interlocked catenane host to be capable of binding and sensing anions, in particular forming strong associations with acetate and dihydrogen phosphate.
混合的卤素和氢键杂[2]联烷已通过阴离子模板Grubbs II催化的RCM剪切机械键形成方法合成。1 H NMR光谱和荧光滴定实验表明,联锁的链烷主体能够结合和感测阴离子,特别是与乙酸根和磷酸二氢根形成强缔合。
