Research

We investigate noncovalent strategies (electrostatics, hydrogen-bonding, halogen/chalcogen bonding, and encapsulation) to selectively recognise anions, cations, and ion-pairs in challenging media. Projects emphasize receptor design (including catenanes and multi-dentate macrocycles), the role of counterions in modulating affinity, and the translation of sensing motifs into aqueous-compatible sensors and extraction systems.

We develop functional polymeric adsorbents and hyper-crosslinked networks that use supramolecular motifs and post-synthetic functionalization to remove chemical pollutants (organic dyes, iodine species, and ionic contaminants) from water. Research integrates design of polymer scaffolds (e.g., tosylated hyper-crosslinked polymers), surface functionalization to tune selectivity, and application testing for fast, efficient adsorption and recyclability.

We design, synthesise and functionalise pillar[n]arene derivatives and related macrocycles to create tunable cavities and recognition sites for selective molecular encapsulation and stimulus-responsive assemblies. Our work spans new synthetic routes (including self-template and strap strategies), structural characterisation (NMR and single-crystal X-ray), and the use of subtle electronic/steric to control binding geometry and supramolecular polymer formation.
