  • Advanced functional porous materials for Chemical industry Energy and Environmental applications.



We seek to correlate structural features with physical properties and to design synthetic strategies to prepare functional materials and to tune their structures and properties. We use synthetic methods from both inorganic and organic chemistry to prepare novel types of material and then use a wide variety of techniques to study their structure and properties. Using suitable organic ligands (predesigned by organic synthetic methods or commercially available ligands) we synthesis new self-assembled materials. Once the structure of new compound is determined by X-ray single crystal diffraction, the obtained bulk materials are characterized by different physical techniques that include powder X-ray diffraction (PXRD), thermo gravimetric analysis (TGA), elemental analysis, vibrational spectroscopy (IR), sorption, etc. The synthesized materials are used for functional studies like chemical separation, gas storage, magnetism, heterogeneous catalysis, conductivity, sensor etc.

Advanced functional porous materials for water remediation:

1. Luminescent MOFs for molecular recognition.


MOF as a chemical sensor has been employed for multiple applications like explosive detection, in vivo neurotransmitter sensing and ion recognition. Chemically stable Zr(IV) and carboxylate based porous fluorescent MOF with free Lewis basic functional groups (like amine, pyridyl ) has been developed for highly selective nitro explosive detection in aqueous phase. A bio-compatible Zr(IV) and carboxylate based MOF based turn-on probe for detection of gasotransmitter H2S in live cells has also been established in our lab. Several other fluorphore-based MOF probes are being studied for diverse sensing and detection purposes, accompanied with high selectivity and sensitivity.

2. Sequestration of Environmentally Toxic Pollutants


A number of new cationic MOFs are being synthesized from N-donor based neutral linkers, which via intermediacy of anion exchange and fluorescence/IR based detection techniques, are being employed for selective anion recognition and detection phenomena. Interesting anion-responsive tunable luminescent properties have been the signature attributes for this class of compounds. These compounds have also been sought for the capture of toxic oxyanions in aqueous medium.

Industrially Relevant Hydrocarbon Separation:

Separation of hydrocarbon species holds great importance in industrial applications. From the application-perspective, the separation of light hydrocarbons, especially those having related physical properties and similar molecular sizes is highly challenging for industrial applications. Adsorption-based separation seems the best alternative against the expensive and energy-intensive azeotropic and extractive distillation methods for achieving such separation. In our lab, functional MOFs are being designed and developed for the separation of industrially relevent hydrocarcons sepations including Benzene/cylohexane, o/m/p-xylenes, C2H2/CO2, C2H2/C2H4, C2H4/C2H6, C3H4/C3H6, and C3H6/C3H8 etc.

Ion conductivity/Fuel Cell Membranes Materials


Fuel cells have shown great potential to produce energy in higher efficiencies with no environmental pollution. H+ and OH-conduction properties of MOFs evolved as an outcome of some design-principle, coupled with those subsequent to post-synthetic modification (PSM) are currently being studied for intriguing revelation of high proton conductivity and chemical stability features in both anhydrous and humidified conditions.

Magnetic Materials


Single molecule magnets (SMMs) and Single chain magnets (SCMs) have been regarded as important classes of compounds, derived from coordination chemistry-aided apposite design principles. Stemming from chelating ligands, mostly oxygen-donors as well as, mixed (N- and O- donating) schiff base linkers, coupled with oxophilic lanthanide ions having large unquenched orbital angular momentum, an overall increase in the magnetic anisotropy values for the concerned Ln(III) homometallic/ 3d-4f heterometallic complexes are manifested. These lead to slow magnetic relaxation guided SMM behaviours of these complexes. Also we are currently pursuing the development of materials which can respond to magnetic stimulus. Such compounds exhibiting spin transitions on application of external fields are promising candidates for several important applications.
