The Subhajit
Bandyopadhyay Group
Light Triggered Chemistry Research Laboratory

We work on the synthesis of molecules, study the kinetics. photochemical, and photophysical properties of the synthesized molecules to understand their behavior. Our molecules toggle between two structures using light and we utilize the structural changes to control several properties such as aggregation-disaggregation, supramolecular assembly - disassembly, differential binding properties, and so on.

+ Synthesis and Studies of Light Gated Modulation of Properties

◘ Photonic Molecular logic gates.
◘ Formation and dissociation of supramolecular assembly.
◘ Light activated binding to biomolecules.
◘ Light activated metal/anion binding.

+ Sensors

The government and various non-government organizations are vigilant about environment pollution by various chemical entities, both natural as well as man-made. Although there are many regulatory bodies to monitor the environmentally relevant chemical species, there is a need to develop fast, sensitive and selective methods to monitor them.

Our featured work on sensors:

+ Bio-Inspired Catalysis

We are also involved in designing of efficient organo-catalysts taking lessons from the Nature and study their activities and mechanisms.

Recent work from our group demonstrates the use of a photoswitchable dicarboxylic acid as a glycosidase mimic. The activity can be turned 'off' and 'on' using visible and UV light respectively.

Chemical Communications, 2014, 50, 10577-10579 DOI: 10.1039/C4CC03394A

+ Smartphone Chemistry

With a rise in the development of mobile learning environments, smartphone based apps have become an appealing method of teaching in the classroom and labs. Our goal is use the features of smartphones like camera to study enzyme kinetics and develop low-cost spectrophotometry undergrad experiments. We aim to turn the smartphone into a portable colorimeter and a spectrometer.

◘ Titration ColorCam: The Sound and Feel of Titration Endpoints.
We have developed a smartphone aid for the colourblind and visually impaired students for performing titration experiments. Available freely on Google Play Store. View the application demonstration here.
