Highly efficient cold-white light emission in a [Au2CuCl2(P∩N)2]PF6 type salt

Abstract

In the trinuclear, heterometallic cluster compound [Au2CuCl2(P∩N)2]PF6 metallophilic interactions give rise to very efficient cold-white light emission as a result of at least two thermally non-equilibrated emissive triplet states (one of mainly Cu → py and the other of Au → py character, respectively) with exceptional spin-orbit coupling and short emission lifetimes, which are competitive to PtII- and IrIII-based emitters.
