Polymer Chemistry, and Organic Chemistry
Functional Organic Polymers and Nanostructures
Our research program is focused on the rational design and development of functional organic polymers and nanostructures. Our group’s core strength is design, development, synthesis, and structural characterization of smart functional polymers and self-assembly of organic molecules and nanostructures. Students in my research group are trained at the interfaces of organic chemistry, polymer chemistry and nanoscience, and gain expertise in the design and synthesis of small molecules, polymers and nano/colloidal particles. In addition to the synthesis of materials, students routinely perform electron microscopy, X-ray diffraction, and electrochemical and optical characterization, alongside basic material characterization.
Current projects in my research group are: i) design and development of elastic and self-healable materials for organic electronics; ii) design principles for smart and mechano-responsive π-conjugated polymers; and iii) shape-controlled synthesis of organic π-conjugated polyhedral nanoparticles.
