Dr Sanjib Das completed his Ph.D. in Chemistry from Indian Institute of Technology (IIT) Kanpur, UP, after completing M.Sc. in Chemistry from Banaras Hindu University. He worked for more than five years as a Postdoctoral Research Fellow at the various world class institutions like University of Heidelberg in Germany, National Institute for Materials Science (NIMS) in Japan, Weizmann Institute of Science in Israel prior to join at CSIR-Institute of Minerals & Materials Technology (IMMT) as Scientist in March 2012. He has achieved a vast expertise in the field of Organic Driven Materials Science combining Supramolecular Host-Guest Chemistry, Opto-Electronic and Luminescent Sensor Materials, Stimuli-Responsive Molecular Switches and Nanoparticles, Conducting Polymers, Porous Organic and Metal-Organic polymeric Materials, Catalysis. He is recipient of prestigious and highly competitive "Dean of Faculty" and "NIMS Researcher" postdoctoral fellowship from Japan and Israel. He qualified National Eligibility Test in chemical science and Graduate Aptitude Test in Engineering (All India rank 111). He has published in several very high impact international journals from Willey, ACS, RSC publishers (17, h-index-11). Currently, he has been working as a senior scientist at Materials Chemistry Department, CSIR-IMMT and his present research focused on the Rational Synthesis of Nanoporous polymeric Materials and its Composites using organic chemistry as a major driving tool towards small gas (CO2 and H2, and CH4) capture and separation, detection and removal of toxic organic micro-pollutants and heavy metal ions from wastewater, opto-electronic materials for energy storage, heterogeneous catalysis for industrial wastewater treatment.

  • Our research interest mainly focus on molecular engineering towards materials sciences, in particular, design of organic as well as hybrid metal-organic based state-of-the-art smart functional and tunable macromolecules and hybrid materials capable of addressing fundamental and social major issues of energy, environment, and industry. The design and synthetic strategy comprises basic knowledge of organic and macromolecular chemistry and some cases lesson from biological phenomenon. Currently we are interested on the following domains:
  • Nonlinear Optical Materials: Design and synthesis of chiral “metal-ligand” conjugate exhibiting extremely high solid-state NLO activity and to modulate their properties in bulk state via various external stimuli.
  • Porous Polymeric Materials: Construction of “tuneable” organic and metal-organic based nano-/micro-porous polymeric materials through proper design and synthesis of organic building blocks for targeted and controlled functionality.
  • Organic Semiconductors: Design and synthesis of molecular/supramolecular scaffolds comprising segregated p- and n- type organic semiconductors for efficient photo-energy conversion materials.
  • Functional Dynamic Supramolecular Architectures: Functional organic entities through judicious molecular engineering followed by supramolecular self-assembly through non-covalent forces generates well-defined structures that can show interesting and enhanced functionality in bulk state.
