Research Abstract

Over the last few years the exploration into ruthenium compounds and the field of coordination chemistry have grown. Ruthenium (II) and ruthenium (III) carry oxidation states that accommodate six-coordinated octahedral configurations in which axial attached ligands can determine chemical and steric properties. UV/Vis spectrometry, H1 NMR, and electrochemical voltammetry will be used to gather data from previously synthesized ruthenium (II) coordination complexes. We hope that by substituting various R groups on three different locations of our ruthenium (II) complex we will be able to control for many physical and chemical changes. After collecting the data from all three complimentary techniques we hope to directly compare E1/2 values, MLCT energies and NMR chemical shifts. Based on the literature we know that there will be a direct relationship between these results based on our chosen substituents.

Ligand Substitution of Ruthenium (II) Complexes that Elicit Physical and Chemical Changes
