Benzo-extended N^N^N-chelated tetracoordinate boron hetero[8]helicene featuring an inner N–B–N helical rim for circularly polarized TADF
A π-extended tetracoordinate boron [8]helicene, Hel-BNN, was synthesized, exhibiting efficient TADF and pronounced chiroptical properties. A sensitized OLED using it exhibited an EQE max of 21.9% and displayed circularly polarized electroluminescence.
