Helically chiral Pd() complexes containing intramolecular Pd Pd metallophilicity as circularly polarized molecular phosphors
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...

Summary: | 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 charge-transfer excited states has been recorded in diluted solutions.
Pallas's shining helixes: single-helical and double-helical oligonuclear pincer-type palladium(
ii
) arylacetylide complexes exhibit circularly polarized phosphorescence with MMLCT parentages in fluid solutions. |
