A Giant Molecular Spoked Wheel — •Stefan-Sven Jester, Robert May, and Sigurd Höger — Kekulé-Institut für Organische Chemie und Biochemie, Rheinische Friedrich-Wilhelms-Universität Bonn, Gerhard-Domagk-Str. 1, 53121 Bonn
The modular synthesis of a defined, rigid molecular spoked wheel structure with the sum formula C1878H2682 and a diameter of about 12 nm is described. The attached 96 dodecyl side chains provide the solubility of the 25260 Da compound in common organic solvents. At the octanoic acid/highly oriented pyrolytic graphite interface, the molecules self-assemble to form an ordered 2D lattice, which is investigated by scanning tunneling microscopy, displaying their structure with submolecular resolution.
