We report efforts to prepare a molecular spur gear utilizing a convenient synthesis of a norbornane stator that positions two interdigitated diyne-linked triptycenes in parallel alignment. While gearing was not observed by 19F NMR for a −CF3-labeled analog at temperatures as low as 213 K, we used molecular dynamics simulation and 2D metadynamics calculations to understand the gearing/slippage energetic profile for various molecular spur gears to guide future designs of these systems.

具有三茂铁转子和基于降冰片烷的定子的分子正齿轮。

我们报告了努力准备利用分子合成降冰片烷定子的便利合成的分子正齿轮,该定子在平行排列中定位两个相互交叉的二炔连接的三联烯。虽然在低至213 K的温度下未通过19 F NMR观察到-CF 3标记的类似物的齿轮,但我们使用分子动力学模拟和2D元动力学计算来了解各种分子正齿轮的齿轮/滑移能量曲线,以指导未来这些系统的设计。
