本文报道了钌基分子齿轮原型的合成，该分子齿轮原型由溴化或非溴化五苯基膦配体作为锚定单元和具有芳基官能化吲唑的三脚架配体作为旋转齿轮组成。钌配合物的单晶结构表明，附加的芳基基团增加了嵌齿轮的表观直径，使它们大于锚定单元的直径，从而使它们适合于一旦配合物将被吸附在表面上的分子间齿轮运动。
This paper reports the synthesis of ruthenium‐based molecular gear prototypes composed of a brominated or non‐brominated pentaphenylcyclopentadienyl ligand as an anchoring unit and a tripodal ligand with aryl‐functionalized indazoles as a rotating cogwheel. Single crystal structures of the ruthenium complexes revealed that the appended aryl groups increase the apparent diameter of the cogwheel rendering them larger than the diameter of the anchoring units and consequently making them suitable for intermolecular gearing motions once the complexes will be adsorbed on a surface.
