基于UPy构建的动态索烃等工作的研究基础,设计合成一系列萘环基团桥联的不同醚链长度连接基的双功能UPy分子,系统研究了其环链平衡机理.既可以选择性地在很宽的浓度范围内(0-500mM)控制形成稳定的环状单聚体,又可以控制性地增长连接基来降低临界聚合浓度(CPC＜10mM).这为环-链平衡理论提供了一类简单又精致的模型,即可以通过控制柔性链的长短,也可利用动态索烃方便地调控双官能化线性分子在超分子聚合中的环链转化.设计合成了包含三个识别位点的三态分子梭，即磷氧基团，脲基基团和二节基胺基团。大环可以在酸碱以及离子刺激作用下选择性地停留在三个不同的识别位点。此类基于磷氧功能团的分子梭体系在金属催化等领域的应用研究正在进行中。
