Palladium(0) NHC complexes : a new avenue to highly efficient phosphorescence
Abstract
We report the first examples of highly luminescent di-coordinated Pd(0) complexes. Five complexes of the form [Pd(L)(L’)] were synthesized, where L = IPr, SIPr or IPr* NHC ligands and L’ = PCy3, or IPr and SIPr NHC ligands. The photophysical properties of these complexes were determined in toluene solution and in solid state and contrasted to the poorly luminescent reference complex [Pd(IPr)(PPh3)]. Organic light-emitting diodes were successfully fabricated but attained external quantum efficiencies of between 0.3 and 0.7%.
