Tuning the circularly polarized luminescence in homoleptic and heteroleptic chiral Cr^III complexes.

ABSTRACT: A series of highly emissive inert and chiral Cr^III complexes displaying positive and negative circularly polarized luminescence (CPL) within the near-infrared (NIR) region at room temperature have been prepared and characterized to decipher the effect of ligand substitution on the photophysical properties, more specifically on the chiroptical properties. The helical homoleptic [Cr(dqp-R)₂]³⁺ (dqp = 2,6-di(quinolin-8-yl)pyridine; R = Ph, ≡-Ph, DMA, ≡-DMA (DMA = N,N-dimethylaniline)) and heteroleptic [Cr(dqp)(L)]³⁺ (L = 4-methoxy-2,6-di(quinolin-8-yl)pyridine (dqp-OMe) or L = N ²,N ⁶-dimethyl-N ²,N ⁶-di(pyridin-2-yl)pyridine-2,6-diamine (ddpd)) molecular rubies were synt
