Over the past decade there has been considerable interest in molecular machines such as gears, brakes, tweezers and motors. Among many moleculars of interest, triptycene is a promising candidate for molecular rotor designs because the rigid geometry in triptycene, with its three phenyl rings forming a three-bladed structure that can rotate along with an axis. Here, we synthesized using 9-alkynyl-triptycene (9-AT) for a molecular rotor attached on plane. The 9-AT was synthesized using4-(Anthracen-10-yl)-2-methylbut-3-yn-2-ol derived from 9-bromoanthracene and 2-methyl-3-butyn-2-ol via a Sonogashira cross-coupling reaction and benzyne under a Diels-Alder cycloaddition. The final product was characterized using H1-NMR, FT-IR and UV-VIS spectroscopy. |
