Abstract

Abstract : Making Pd(ii ) brightly shining: mononuclear analogues are non-emissive, but folded dinuclear palladium(ii ) diacetylide complexes phosphoresce from MMLCT excited states with quantum yields up to 48%. Abstract : Dinuclear pincer-type cyclometalated Pd(ii ) complexes with foldable diacetylide ligands show crystallographically determined intramolecular Pd⋯Pd contacts of 3.203–3.380 Å. In deoxygenated fluid solutions, these Pd(ii ) complexes are highly phosphorescent in the red region with emission quantum yields up to 48%, which has been ascribed to metal–metal-to-ligand charge-transfer (MMLCT) excited states in nature.
