Carbon-centred chirality of the pincer-type cyclometalated ligands is transferred to the helical chirality of dinuclear and tetranuclear Pd( ii ) arylacetylide complexes, and hence phosphorescence with quantum yields up to 50% and dissymmetry factors in the 10 −3 scale from the metal-metal-to-ligand...
