preparation of [2]rotaxanes containing an electrochemically and optically active osmium(II) bipyridyl macrocyclic component mechanically bonded with cationic pyridinium axles. Such interlocked host systems are demonstrated to recognise and sense anionic guest species as shown by 1H NMR, luminescence and electrochemical studies. The rotaxanes can be surface assembled on to gold electrodes through anion templation
我们报告了 [2] 轮烷的制备,其中包含与阳离子吡啶鎓轴机械结合的电化学和光学活性锇 (II) 联吡啶大环组分。1 H NMR、发光和电化学研究表明,这种互锁的主体系统可以识别和感知阴离子客体物种。轮烷可以在点击铜(I)催化的Huisgen环加成条件下通过阴离子模板表面组装到金电极上,形成轮烷分子膜,在去除模板后,对氯化物进行电化学反应和选择性反应。
