We combined a stilbene motif with two benzimidazolium arms to prepare new sorts of supramolecular building blocks and examined their binding properties towards cucurbit[n]urils (n=7, 8) and cyclodextrins (beta-CD, gamma-CD) in water. Based on the(1)H NMR data and molecular dynamics simulations, we found that two distinct complexes with different stoichiometry, i. e., guest@beta-CD and guest@beta-CD2, coexist in equilibrium in a water solution of the (Z)-stilbene-based guests. We also demonstrated that the bis(benzimidazolio)stilbene guests can be transformed from the (E) into the (Z) form via UV irradiation and back via thermal treatment in DMSO. ER -
