Recognition and Sensing of Anion and Ion-pair: We design and synthesize multipodal receptors, dimeric and covalent molecular capsules with diverse binding motifs for selective recognition and extraction of anion and ion-pair, fluorophoric receptors for sensing. Our present research mostly focuses on (i) halogen and hydrogen bonding based recognition of phosphates and perrhenate, ReO₄^- (surrogate of highly toxic and radioactive by-product pertechnetate, ⁹⁹TcO₄^- in nuclear fuel generation) to address the environmental issues like eutrophication of water body due to excess use of phosphate based fertilizers in agriculture and nuclear waste reprocessing/disposal problems; (ii) chalcogen, halogen and hydrogen bonding based recognition and extraction of anions in aqueous medium to address some of the problems associated in industrial discharged water; (iii) polymer based anion receptors for separation of ions.

Supramolecular Catalysis: We also design and synthesize heteroditopic cages for their potential involvement in regioselective catalysis and unimolecular bimetallic complexes in dual photo catalysis for potential application in the chemical industries.

Molecular Self-assembly and Interlocked Molecular Systems:  We work on template directed interlocked molecular systems (rotaxanes and catenanes) for the development of molecular machines as well as metal ion assisted self-assembly to develop artificial helicates.
