We report a highly efficient one-pot [2+3] clipping method to obtain a new kind of C3-symmetric interlocked rotaxanes through six-fold imine bond formation using a trispyridinium-based p-template. As revealed by solid state structures, the triply interlocked structure is stabilized by p-p interactions and multiple [C�H�O] and [C�H�N] interactions. Based on this p-template protocol, three-terminal [2]rotaxanes can be prepared by a one-pot reaction using stoppered-trispyridinium. Such triply-interlocked molecules serve as a complementary entry to the well-received �axle-and-wheel� type of two-terminal rotaxanes.
