we have designed3 self-inclusive pure crystals [Ru-(phen)3]tfpb2 ((1), phen = 1,10-phenanthroline, tfpb =
tetrakis(bis-3,5-trifluoromethylphenylborate))3a that contain a long-lived emissive ruthenium complex and regular void spaces
to allow diffusional oxygen quenching. This prototype showed an emission quantum yield and lifetime of 0.071(2)
