RIA: Component-Based Mobility-Directed Synthesis

本研究启动提案旨在支持基于单个组分分子迁移率的新型聚合物的开发。分子迁移率由时间尺度和运动几何形状指定，由二维交换核磁共振波谱测定。一种聚合物，聚轮烷，是通过将一个相对不移动的线性组分与一个移动的环状组分穿线而形成的。通过根据分子迁移率明智地选择组分，技术上有用的材料将会出现。* * *

9412294 Beckham This Research Initiation Proposal is to support the development of novel polymers based on molecular mobilities of individual components. The molecular mobilities are specified by the time scale and geometries of motion as determined by 2D exchange NMR spectroscopy. A polymer, polyrotaxane, will be constructed by threading a relatively immobile linear component with a mobile cyclic one. By the judicious choice of components based on molecular mobilities, technologically useful materials will emerge. ***
