π-conjugated Materials for Modern Applications in
Inorganic and Bioinorganic Model Systems
Functional Molecular Systems
Perylenebismides (PBIs)
Among the various pi-conjugated organic chromophores, perylene bis-imides (PBI), and their derivatives, with their intense absorption and fluorescence in the visible spectral region emerged as potential electron-transport systems (i.e. n-type semi-conductors). These molecular systems have near-unity fluorescence quantum yields, excellent CT characteristics, high photochemical and thermal stability, strong electron-accepting capacity and high charge carrier mobilities.
In this connection, we have chosen to develop unsymmetrically functionalized perylenebismide derivatives for modern opto-electronic applications. Our endeavour focuses on the understanding of photophysical properties of the synthesized systems and finding suitable applications for them. Towards this direction, we have developed a few unsymmetrically derivatized PBIs and have investigated their structure, photophysical and elecrochemical characteristics.
Multi-Corrole & Multi-Porphyrin Arrays
Corroles are known for their ability to stabilize metal ions in their higher oxidation states. This aspect had been exploited in a variety of organic transformations utilizing metallocorroles as catalysts. Despite of their wide applications, there are only limited number of functionalized corroles available in literature. Our focus in this direction is towards developing functionalized corroles for various applications. One of our major interests is to synthesize and investigate covalently linked multi-corrole architectures for catalytic and magnetic utilities.
BODIPy
Ligands based on the architecture of Schiff's base are the celebrated choice of inorganic chemists for metal ion coordination and stabilization. These complexes found their deserving position in organic synthesis as well. Albeit their existence for decades, these unique molecular framework of Schiff bases has not been exploited for their ability to bind anions and neutral molecules. In our group, we have explored this novel framework for the recognition of various anions and neutral molecules
