of this species to act as a molecular receptor, the conversion of a hydrazine-pending cyclophane into the pseudo[1]rotaxane and, lastly, the one-pot [1 + 1 + 1] condensation process. The latter was found to smoothly produce the target molecule through an integrative social self-sorting process, a species that was found to behave in water as a discrete self-inclusion complex below 2.5 mM concentration
我们在此提出了一种新的聚阳离子假[1]轮烷的合成,该假[1]轮烷通过在三种不同的醛和肼结构单元的水介质中的腙键以优异的产率自组装。通过分析双醛和三肼的 [1 + 1] 反应导致系统的大环部分,该物质作为分子受体的能力,肼-的转化,依次研究了热力学控制过程。待环烷转化为拟[1]轮烷,最后进行一锅[1+1+1]缩合过程。人们发现后者通过综合社会自分选过程顺利地产生目标分子,该物种被发现在水中表现为浓度低于 2.5 mM 的离散自包含复合物,并在浓度为 2.5-70 mM 时形成超分子聚集体。范围。此外,我们证明了大环环上腙键的异常动力学稳定性如何可以有利地用于将获得的假[1]轮烷转化为其他外官能化大环物种。
