Homoleptic Cr(III) complexes containing anionic tridentate 1,8-(bisoxazolyl)carbazolide ligands are phosphorescent in deaerated solutions with peak maxima in the range of 813-845 nm. The ligand carbon-centred chirality has been transferred to the helical chirality of the complexes and hence induced circularly polarized NIR-emissions with dissymmetry factor in the scale of 2.0 × 10.
含有阴离子三齿1,8-（双恶唑基）咔唑配体的均配型Cr(III)配合物在脱气溶液中具有磷光性，其峰值最大值在813 - 845 nm范围内。配体以碳为中心的手性已转移到配合物的螺旋手性上，因此诱导出不对称因子在2.0×10量级的圆偏振近红外发射。
