We present the design, synthesis and characterization of the Ohio Bobcat Nanowagon, a [5]pseudorotaxane assembly bearing an H-shaped frame threaded into four Cucurbit[7]uril (CB[7]) wheels.  The key motifs in the frame are two benzimidazolium groups, which link a terphenyl drive shaft (the horizontal bar of the “H” frame) to the axle shafts (the vertical bars of the “H” frame). Four pyridinium units terminate the latter. Positive charges at the pyridinium and benzimidazolium units allow the frame and the CB[7] wheels to assemble into the final nanowagon in water. The white solid obtained upon freeze-drying was used for successful scanning tunneling microscopy imaging (STM).
