A tris (pentafluorophenyl) phlorin derivative was bound to a phosphorous(V) central atom. The complex was characterized with electronic spectroscopy, cyclic voltammetry, differential pulse voltammetry, and 1H NMR spectroscopy. The complex was compared with an analogous phosphorous corrole. A novel bis(imino) ligand with a dipyrromethane spacer was developed and bound to several metal centers, including Ni(II) and Zn(II). These complexes and the free-base ligand were characterized with a variety of techniques and structures were confirmed with X-ray crystallography.Thesis976432229
