Chemically activated molecular motors that can undergo a full 360° rotation are rare. Designing such an artificial motor while preserving full directional fidelity is even more challenging. In this issue of Chem, Feringa and co-workers demonstrate that this feat can be accomplished through careful molecular design that takes advantage of point and helical chirality, combined with the dynamic nature of lactones, to induce directional motion around a biaryl C–C bond.

化学活化电机中的完全单向性

能完全旋转360°的化学活化分子电动机很少见。在保持全方向保真度的同时设计这样的人工电机更具挑战性。在本期《化学》杂志中，Feringa及其同事证明了这一壮举可以通过精心设计的分子来完成，该分子设计利用点和螺旋手性，结合内酯的动态性质，诱导围绕联芳基C–C键的定向运动。
