Abstract:The research of molecular capsules offers high application potential and numerous benefits in various fields. With the aim of forming supramolecular capsules which can be reversibly assembled and dissociated by simple external stimuli, we studied interactions between calixarenes containing urea and carboxylate moieties. To this end two ureido‐derivatives of p‐tert‐butylcalix[4]arene comprising phenylureido‐moieties and diacetate‐calix[4]arenes were prepared. The binding of acetate by ureido‐derivatives of cali… Show more
