Transition Metal Complexes of Bidentate and Tridentate Ligands: From Optoelectronic Studies to Supramolecular Assemblies.

Abstract

This article depicts an overview of some of the research in supramolecular chemistry performed by the author over the past few years. This work includes the synthesis of building blocks, bidentate and tridentate 'super donor' ligands that are comprised of H-hpp (where H-hpp = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a] pyrimidine) coupled with various N-heterocycles as well as the synthesis and characterization of the transition metal complexes in self-assembled superstructures. The article also includes the studies of photophysical, electrochemical and density functional theory calculation of the complexes. Thus, the work relies on a combination of synthetic work and optoelectronic studies, and the results are relevant in the greater context of supramolecular chemistry, solar energy harvesting, and its conversion to chemical energy, photovoltaics and inorganic light-emitting device applications.
