Research Highlights :

Organic Synthesis & Organic Electronics

Organic Electronics is a budding interdisciplinary research area focusing on technologies that rely on organic semiconductors instead of traditional inorganic ones. Organic electronics will help us to address the crucial problems of modern society. This field results in low-cost, lightweight, flexible, wearable technologies, energy-efficient lighting, efficient memory devices, and molecular sensors.

Virtually unlimited possibilities of synthetic organic chemistry and compatibility with inexpensive solution-based fabrication techniques make organic semiconductors an extremely viable novel technology of the future.

Research in our group focuses on developing new materials for organic electronics and understanding how molecular structure alters the properties of such materials. For this purpose, we work on molecular design, synthesis, characterization techniques, photophysical studies, computational studies, device fabrication, and characterizations to advance the field of organic electronics and contribute to the development of efficient and sustainable electronic devices for information processing.
