Abstract
Highly luminescent transition metal complexes have captivated chemists with potential apps. as sensors, biol. imaging agents, and photoreductants. Our recent synth. of an amide-bridged Cu dimer, boasting a long decay lifetime and high quantum yield (11 μs, 58%), has piqued our interest in these areas. Altering supporting ligands--while maintaining the diamond core motif--has marked effects on photoluminescence: while the PNP2Cu2 dimer emits intensely, phosphide-bridged PPP2Cu2 displays very weak luminescence. To help elucidate emission mechs., we have prepd. a new PN ligand (PNP sans one supporting phosphine). The PN ligand presented in this talk provides access to monomeric complexes of type [PN]CuL2, which display photophys. properties. surprisingly similar to their dimeric cousins. These complexes present a unique opportunity to tune electronics by subst. of L-type ligands at the metal, or by subst. at the arom. PN backbone. The amidophosphine ligand also yields emissive d10 complexes of Ag, Zn.
