Supramolecular chemistry

We study the reactivity of chemical species arrested in supramolecular cavities or interligand and interparticle spaces. We also develop new colloidal and supramolecular systems to this end.

Recently in our laboratory we have synthesized the first member of a new family of macrocycles - pillar[n]pyridiniums. It is a cyclic tetramer with a highly symmetric strained structure and electron-deficient cavity that recognizes fluoride in water:

We reported the acceleration of an autocatalytic reaction by cucurbit[6]uril host:
