Research goal

     The main focus of the OMED lab is to integrate the synthesis of organic materials and their applications in energy-related devices. We will synthesize conjugated small molecules, polymers and porous polymer networks for their applications in supramolecular chemistry, optoelectronic devices and renewable energy. In modern life, smart electronic and wearable devices including smartphones, smartwatches, blood pressure & heart rate monitor etc. are becoming a necessity. Organic molecules and polymers are finding their use in such devices, for example in displays, sensors etc. In future, to make flexible, stretchable, transparent and self-healing devices, p/n-type molecules and polymers are required to fabricate organic transistors. In the energy sector, renewable energy by solar, wind etc. is to take over the non-renewable sources mainly fossil fuels. In that aspect, organic solar cells are becoming more efficient day by day and will be commercially used in near future. The donor-acceptor conjugated polymers and non-fullerene acceptors construct such highly efficient organic solar cells. Another source of renewable energy is hydrogen generation by water splitting and its storage. For this, porous polymer networks incorporated with different metal catalysts are highly suitable. Currently, the global trend is shifting towards interdisciplinary research. Therefore, research in OMED lab comprising organic chemistry, materials science, device engineering and theoretical understanding can address the challenges of the high-end research goals.
