Highly emissive, redox active amido-bridged Cu_2N_2 diamond core complexes supported by phosphine ligands

Abstract

A series of novel Cu_2N_2 diamond core structures supported by P_2N- ligands have been prepd. These diamond core systems exhibit reversible 1-electron redox processes between the Cu^1Cu^1, [CuCu]^+, [CuCu]^2+ states. The solid-state mol. structures of each show that minimal overall structural reorganization occurs, though minor core distortions are present. Addnl., the Cu^1Cu^1, form is highly emissive (φ > 65%, τ > 10 μs) and gives rise to interesting photoreductive chem. The magnetic, electrochem. and spectroscopic data, as well as initial reactivity studies, will be discussed.
