Synthesis of highly luminescent amido-phosphine complexes of Cu, Ag, and Zn

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.
