Near-infrared circularly polarized luminescence from chiral Yb(iii)-diketonates

We report a rare example of near infrared circularly polarized luminescence (NIR-CPL) in the 920-1050 nm region associated with the f-f transitions of Yb diketonate complexes bearing chiral ancillary ligands. Developing NIR-CPL emitters may have implications from CPL-based (bio)-assays to chiral optoelectronics.
