Indian Institute of Technology (IIT) Indore is developing a smart glass using a viologen-based porous organic polymer (POP) that can control light and heat transmission with a small electric current. This innovation aims to transform how windows function in buildings, making them more energy-efficient and sustainable.
The smart glass responds quickly to electricity, changing its color and transparency to block sunlight and heat when needed or allow it in during cooler conditions. This dynamic adjustment reduces reliance on air-conditioning and artificial lighting, helping lower electricity bills and environmental impact.
Researchers say the use of viologen-based polymers enables fast and reliable color change, making the glass ideal for smart homes and green buildings. The project is being led by Prof Suman Mukhopadhyay (Department of Chemistry) and Prof Rajesh Kumar (Department of Physics), with researcher Dr Sayantan Sarkar under the Translational Research Fellowship (TRF) scheme.
IIT Indore is collaborating with industry partners to ensure the glass can be manufactured using existing factory setups, paving the way for large-scale adoption. The smart glass could soon replace traditional curtains and windows, offering a futuristic solution for climate-responsive architecture.
