Abstract

  • A wedge-shaped D-π-A-π-D emitter APDC-DTPA with thermally activated delayed fluorescence property and a small single-triplet splitting (ΔEst) of 0.14 eV is presented.
  • The non-doped NIR device exhibits excellent performance with a maximum EQE of 2.19% and a peak wavelength of 777 nm.
  • 10 wt% of APDC-DTPA is doped in TPBi host, an extremely high EQE of 10.19% with an emission peak of 693 nm is achieved.
