TL;DR: This study shows a molecular design strategy for controlling the dihedral angle of two carbazole donors linked to a 2,4-diphenyl-1,3,5-triazine acceptor by a phenyl unit and concludes that materials containing two substituted-ortho donors or one -ortho and an adjacent -meta have the smallest energy gaps and the shortest delayed fluorescence lifetimes.

TL;DR: The TADF exciplex allows harvesting of the holes and electrons that piled up at the EML-ETL interface and transfers the resultant excited state energy to the phosphorescent emitter through Förster and/or Dexter energy transfer.

TL;DR: In this paper, the photophysics of a donor-acceptor molecule with 2,4,6-triphenyl-1,3,5-triazine and phenoselenazine acceptor and donor units were studied.

TL;DR: It is shown that external quantum efficiencies as high as 16% can be obtained for a structure with a correlated colour temperature close to warm white, together with colour rendering index close to 80, and in their performance stability that provides the true breakthrough.

TL;DR: Solid-state electroabsorption is demonstrated as a powerful tool for probing the charge transfer character and state mixing in the low-energy optical transitions of two structurally similar thermally activated delayed fluorescent materials with divergent photophysical and device performances.
