A conformational study of rotaxanes has been performed. The proportion of different rotamers was investigated for threads and for threads incorporated into rotaxanes. This investigation was performed by using solution and solid‐state NMR spectroscopy, single‐crystal XRD, and PXRD. How the conformational population is affected when the thread is incorporated into the macrocycle has been evaluated.
轮烷的构象研究已经进行。对不同的旋转异构体的比例进行了研究,研究了螺纹和引入轮烷中的螺纹的比例。这项研究是通过使用溶液和固态NMR光谱,单晶XRD和PXRD进行的。已经评估了将线程合并到大循环时如何影响构象总体。
