The chiral spin–flip luminophore [Cr(ddpd)2]3+ can be resolved into enantiopure material by chiral HPLC. The corresponding enantiomers show very high luminescence dissymmetry factors of up to ∣glum ∣≈ 0.093 in circularly polarized luminescence (CPL) measurements for the “ruby-like” phosphorescence transition 2E/2T1 → 4A2 in the near-IR region around λ ≈ 775 nm.
