在正确的方向上的推力：两种不同的盘形配体（一个三单齿配体和一个六单齿配体）和三个Ag+离子分别被用作轴承和滚珠，用于分子推力滚珠轴承的构造（见示意图）。旋转通过分子内、可逆的多点配体交换和协同作用的翻转运动的组合发生。
A thrust in the right direction: Two different disk-shaped ligands (a tris-monodentate and a hexa-monodentate ligand) and three Ag+ ions have been used as bearings and balls, respectively, in the construction of a molecular thrust ball bearing (see schematic representation). Rotation occurs through a combination of intramolecular, reversible multipoint ligand exchange and flip motions that act in concert.
