About Us Big Image

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.

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

About Us Big Image
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.

About Us Big Image


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.

Teaching

Chemical Perspectives of Biological Pathways

How does nature make, transform, and manipulate biological molecules? This lecture course focuses on the fundamentals of chemical reactions in biological systems and more importantly, the chemical logic behind them.

Reaction Mechanisms in Organic Chemistry

This teaching course traces a reaction mechanism as a step by step sequence of elementary reactions by which overall chemical change occurs.

Physical Methods of Structural Elucidation

This lecture course features concepts that explain the process of determining the chemical structure of a compound. The characterization techniques taught include Nuclear Magnetic Resonance (NMR), mass spectrometry, and X-ray crystallography among others.

Publication related to teaching labs

Many moons ago, when I was teaching the spectroscopy lab, a cool and easy experiment to obtain the C=O stretch in the electronic excited state was designed. It did not require any expensive instruments and expertise. It requires skills in basic arithmetic though!

Subhajit Bandyopadhyay

Subhajit Bandyopadhyay did his MSc from Indian Institute of Technology (IIT) Kanpur. He did his doctoral research under the supervision of Professor Reginald Mitchell at University of Victoria, British Columbia. This was followed by a postdoctoral position with Professor Ron Breslow at Columbia University in the city of New York. Following the footsteps of all his gurus, he believed that his education would be incomplete without a Cambridge education. Therefore, he spent a year with Prof. Florian Hollfelder's lab at the University of Cambridge before joining IISER Kolkata as an Assistant Professor.
