Abstract

The first portion of this dissertation entails the development of new transitionmetal salen complexes, which are used to chelate lanthanides in their compartmental units (both cis and 3,3'-methoxy oxygens). The resulting complexes possess the ability to be used as sensitizers for near-infrared emission and MRI contrasting agents. The second part details the rapid synthesis of imidazo[I,5-a]pyridines from pyridyl ketones, aromatic aldehydes, and ammonia acetate in acetic acid via microwave assisted organicsynthesis. Lastly, the imidazo[I,5-a]pyridine scaffold was further examined as a ligand chelated with RuII, FeIII, and VOIV salts.
