Our research group is multi-disciplinary in nature and situated at the interface of Organic, Physical and Material Chemistry. As a Polymer Chemistry research group, our motto is to design and synthesis of new functional polymers for targeted applications. We endeavour through development and adaptation of synthetic methodology along with extensive physical characterization to achieve our research objectives. Our major research activities are shown below.
(A) Fundamental investigation on polymerization mechanism and kinetics
In this very broad research area, our group will specifically focus on the development of new organo-catalyst to control the microstructure of the polymer such as tacticity, sequence (primary structure), molecular weight distribution etc, which will allow us to have a deep understanding on structure-property relationship to develop advanced functional material.
(B) Plastic multiferroic materials
Magnetism and ferroelectricity are two key components for various technological applications and which are generally mutually exclusive in nature. However, it has been suggested that intimating those two effects could leads to an interesting cross-coupling phenomenon. In this context, our approach will be to organize the electric and magnetic dipoles on a foldamer scaffold to achieve the multiferroic properties in a plastic material.
(C) Biomimetic cascade reactions within the compartment of Sequence-controlled polymer chain
Although the catalytic activity within the single-chain polymeric nanoparticles or asymmetric catalysis within the helical cavity of the foldamers have been reported. However, the catalytic activities are far away to meet enzymatic efficiency especially for the selectivity issue. The structural complexity in the artificial macromolecules are too low to be compared with the native structure of an enzyme. So, our objectives are two-fold such as (i) Design, synthesis and characterization of macromolecules, which folds into a higher order (tertiary and quaternary) structure (ii) A successful implementation of the former task will be utilized for the enzyme mimetic applications such as catalytic activities and cascade reactions.
