About Bio Materials Research Lab

Porphyrin-based functional photonic materials have been the cornerstone of research because of their structural rigidity, thermal stability, photochemical, and electrochemical properties. Linking porphyrins to material systems can improve the photochemical and redox properties of the systems. To facilitate the absorptivity of photo absorbers in case of photochemical devices nano materials are functionalized with chromophores such as porphyrin, metalloporphyrin and azo molecules. Our report shows that Porphyrin functionalized carbon nanomaterial shows high third order non-linear optical properties. Nano-hybrid shows better solvatochromism and fluorescent quenching. The extensive quenching is owing to an effective electron or energy transfer from porphyrin to nano-hybrid.

Our research interests also include the design and synthesis of cobaloximes with new or modified equatorial and axial ligands. Cobaloxime complexes are among the best synthetic transition metal catalysts known for H2 production. Our interest here to synthesize and characterize new organometallic compounds for H2 production. We reported single crystal X-ray structure of many new cobaloximes. Thermotropic liquid crystalline properties of cobaloxime have been reported for the first time. The crystal structures of various organic compounds with medicinal, biological and pharmaceutical importance have been reported from our lab.

The research focus of this lab is to functionalize carbon nanomaterials for the sensor and non-linear optical applications. Our research interests also include synthesis of cobaloximes with new or modified equatorial and axial ligands, biologically and medicinally important organic molecules.
