About
Abdul Wahab did his MSc in Chemistry from Dibrugarh University and PhD (supervisor: Dr. S. Mahiuddin) from RRL Jorhat (CSIR-NEIST). He did his first postdoc (2005-2007) with Prof. Puspendu K Das at Indian Institute of Science, Bangalore and second postdoc (2008-2013) with Prof. Josef Michl at his Prague Lab (J. Heyrovsky Institute of Physical Chemistry). He served University of Science & Technology Meghalaya for two year as Head of the Department of Chemistry. He visited Institute of Organic Chemistry & Biochemistry, Prague as visiting scientist in May 2015. He then joined the erstwhile Cotton College State University (CCSU) as an assistant professor in Oct 2015. Now he is supervising PhD students on the broad area of Physical Organic Chemistry along with teaching the HS, UG and PG students at Cotton University, Guwahati. He likes to play badminton.

Research Overview:
Our research group explores the design, synthesis, and functional understanding of organic materials with tailored excited-state properties. We focus on three core classes of materials:
- Singlet Fission Materials – for next-generation photovoltaics, enabling substantial increase in efficiency through multiexciton generation.
- Aggregation-Induced Emission (AIE) Materials – designed for high-performance optoelectronic and medical applications where traditional chromophores fail due to aggregation-caused quenching.
- Charge-Transfer Materials – with engineered donor–acceptor architectures, these systems enable precise control over electronic and photophysical properties, crucial for energy conversion devices.
Our approach combines synthetic chemistry with advanced characterization tools, including:
- Photophysical techniques (steady-state and time-resolved spectroscopy)
- Electrochemical analysis (Cyclic Voltammetry)
- Theoretical insights via DFT calculations
- Structural investigations using XRD and thermal analysis
By integrating experimental and computational tools, we aim to uncover the structure–property relationships that govern key excited-state phenomena, enabling the rational design of functional materials for energy and optoelectronic technologies.
