A benzyl substituted 4-pyrrolidinopyridinium salt (G) with multiple active sites including benzyl, pyridinium and pyrrole groups has been synthesized. The interaction between G and a series of cucurbit[n]urils (TMeQ, Q, Q, Q), has been studied both in aqueous solution and in the solid state. The binding interaction site between G and the Q[n] can be controlled by the different size of the cavity of the Q[n]s. In the case of TMeQ, the benzyl is accommodated within the cavity, whilst for Q and Q, the pyrrole ring and the benzyl are accommodated within the cavity of the Q[7/8], and the latter can shuttle on the guest G in a state of dynamic equilibrium. For the larger cavity of Q, the entire G molecule is located within the cavity of the Q.
