Research Area: Polymer Chemistry |
Research Focus: 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) Functional polypeptides Having the same backbone as proteins, synthetic peptides make interesting biomaterials. Polypeptides are often synthesized in one step using controlled ring-opening polymerization (ROP) of N-carboxyanhydride monomers (NCA), in contrast to discrete oligopeptide synthesis (SPPS). Among them we are particularly interested with polyprolines. (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) Folding of Periodically-grafted amphiphilic Polyamides Through-bond and through-space electron transport are two ways in which electrons can be transported in a material. Conjugated oligomers/polymers and their ability to transport electrons through bonds have been extensively used in optoelectronics applications for decades. However, in biology, long-range electron/charge transport largely relies on the spatial organization of π-surfaces such that strong electronic coupling between the frontier orbitals (through-space) of adjacent molecules takes place during molecular recognition in DNA, excitonic coupling in photosynthesis, etc. Electron transport through space requires higher-order structures such as proteins or DNA double helixes. It is for this reason that we strive to design new materials for electron transport through space. |
