In this first year, a new series of molecular gears have been synthesized. They are 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. 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. The STM studies have been started but are not conclusive yet.The nano-winch has also all been successfully synthesized with a family of loads of a wide variety exhibiting very different structures from fullerenes, triptycenes, and porphyrins.

在这第一年，一系列新的分子齿轮已经合成。它们是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作为旋转齿轮的三脚架配体组成的基于三溴化铵的分子齿轮原型。附加的芳基增加了嵌齿轮的表观直径，使得它们大于锚定单元的直径，因此一旦络合物将被吸附在表面上，使它们适合于分子间齿轮运动。STM的研究已经开始，但还没有定论。纳米绞盘也已经成功地合成了一系列的负载，表现出与富勒烯，三蝶烯和卟啉非常不同的结构。
