Self‐assembly of the amphiphilic π‐conjugated carbenium ion ATOTA‐1 + in aqueous solution selectively leads to discrete and highly stable nanotubes or nanoribbons and nanorods, depending on the nature of the counterion (Cl − vs. PF 6 − , respectively). The nanotubes formed by the Cl − salt illustrate an exceptional example of a structural well‐defined (29±2 nm in outer diameter) unilamellar tubular morphology featuring π‐conjugated functionality and high stability and flexibility, in aqueous solution.
