Herein is presented the doctoral research of Logan Rockwell Beck. We first report the development a library of osmium(II) polypyridyl complexes and characterize them for use in photoredox catalysis. We then report a triplet-triplet annihilation upconversion system that produces an oxidizing excited state and exhibits a remarkable 1.25 eV anti-Stokes shift. This upconversion system is then applied to dual nickel/photoredox catalyzed C-O cross-coupling. Finally, we discuss efforts towards the remote arylation of aliphatic amines through 1,5-HAT.
