Abstract

Luminescent lanthanide complexes provide a rich variety of radiative f–f and d–f transitions, covering a wide range of emission spectra from ultraviolet to near-infrared. One field where lanthanide complexes are particularly favorable is circularly polarized luminescence (CPL), due to the electric-dipole forbidden nature of f–f transition endowing them with theoretically high dissymmetry factor (g_lum). Circularly polarized luminescent lanthanide complexes can be designed by incorporating chiral ligands to induce molecular chirality. This review summarizes the ligand design in small-molecule circularly polarized luminescent lanthanide complexes classified by different chiral groups, aiming to shed light on how the structure of chiral ligand influences the photophysical and chiroptical properties of a lanthanide complex, and provide insight into further development of chiral ligands for high-performance CPL emitters.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
