| Research Abstract |
We designed molecular gears with two or more three-toothedtriptycene frameworks attaching to an anthracene base. The target compounds weresynthesized by cross coupling reactions of 1,8-diiodoanthracenes and 9-ethynyltriptycenederivatives. We evaluated the effects of linker lengths, distances between the axes, andgear shapes on the gear parallel nature based on molecular structures examined by X-rayanalysis and DFT calculations. The dynamic behavior of these compounds was observed byvariable temperature NMR measurements to discuss their rotation mechanism.
