abstract = {Organic light-emitting diodes (OLEDs) featuring circularly polarized (CP)
electroluminescence (EL) are gaining tremendous attention for their potential
in advanced display and photonic applications. Chiral organic molecules and
4d and 5d metal complexes have been extensively studied for their role in the
emissive layer of these devices. Here, pioneering work demonstrating EL
emission from a chromium(III) complex is presented. Notably, by leveraging
the highly polarized spin-flip transitions of enantiopure CrIII complexes, a
proof-of-concept device showcasing near-infrared (NIR) CP EL with peaks at
726 and 747 nm and corresponding dissymmetry values up to 0.015 and
−0.029 is developed. These findings highlight the potential of earth-abundant
CrIII complexes for cutting-edge chiral optoelectronic applications in medicine,
security, and quantum communications},
