Unlocking efficient near-infrared circularly polarized phosphorescence reaching 800 nm in cyclometalated Pt(ii) complexes

Abstract

We report a promising strategy to design efficient NIR chiral Pt(II) complexes via ligand regulation and planar chirality formation, affording binuclear Pt(II) enantiomers that exhibit unprecedented NIR CPP reaching 800 nm, photoluminescence quantum yields of up to 35.4%, and luminescence dissymmetry factors of ∼3.9 × 10⁻³.
