Synthesis and characterization of ruthenium polypyridyl complexes: Development of multielectron reducing agents and synthesis and investigation of mono- and bis -osmium pentaammine pyridyl viologen complexes for electron transfer studies

Sangsub Han, University of Nebraska - Lincoln

Abstract

This thesis is comprised of two investigations with a draft of manuscript based on research from chapter 1. The first chapter presents the syntheses and characterization of ruthenium polypyridyl complexes: Rubpy(DMQpy) 2(PF6)6 and Ru(DMQpy)3(PF6) 8. These complexes, which may have to be useful as 4-electron or 6-electron reducing agents, are synthesized and characterized using UV-visible spectroscopy, fluorescence spectrophotometry, electrochemistry, and NMR spectroscopy. The second chapter presents the syntheses and characterizations of mono- and bis-osmium pentaammine complexes with a pyridyl viologen ligand. The electron transfer in the mixed-valence complex was investigated using spectroelectrochemistry and NIR spectroscopy. ^
