A new class of wheels, based on subphthalocyanine fragments, for future incorporation in functional nanovehicles is reported. The syntheses of a symmetric wheel, a nitrogen-tagged wheel, and their ethynyl-bridged homodimers are presented. Theoretical calculations and STM imaging demonstrate the advantage of a bowl-shaped structure and the efficiency of the tag for STM imaging.
