Research Areas:

Research activities of our group are focused on exploring the manifold of molecular electronics ranging from organic photovoltaics, light-emitting diodes and field-effect transistors. Our interdisciplinary approach includes synthesizing multifunctional conjugated polymers and oligomers with novel properties and studying their characteristics working at the interface of chemistry, physics and materials engineering. We take advantage of molecular structures to fine tune the desired properties through molecular design and robust synthetic strategies.

The research group at present is actively engaged in developing π-conjugated polymers and oligomers for-

  • Organic Solar Cells
  • Singlet Fission
  • Electrochemical Energy Storage Devices
  • Organic Light-emitting Diodes
  • Thermally Activated Delayed Fluorescence (TADF)
  • Field-Effect Transistors
