Two new ionic dinuclear Ir( iii ) Schiff base complexes which are straightforward to synthesise have luminescence quantum yields as high as 37% in neat films. These are the first examples of dinuclear ionic Ir( iii ) complexes that display aggregation-induced phosphorescent emission (AIPE). Two new ionic dinuclear Ir( iii ) Schiff base complexes are shown to possess a luminescence quantum yield as high as 37% in neat film.
