Highly Efficient Thermally Activated Delayed Fluorescence Emitter Developed by Replacing Carbazole With 1,3,6,8-Tetramethyl-Carbazole

open access: yesFrontiers in Chemistry, 2019
Carbazole (Cz) is the one of the most popular electron donors to develop thermally activated delayed fluorescence (TADF) emitters, but additional groups are generally required in the molecules to enhance the steric hindrance between Cz and electron ...

Strategies for Enhancing Efficiency and Operational Stability in Green Phosphorescence-Sensitized Fluorescence (PSF) Organic Light-Emitting Diode (OLED) Technology. [PDF]

open access: yesSmall
Efficiency and stability of PSF OLEDs can be obtained by improving the terminal emitters (TE's) extinction coefficient (ε) and a large spectral overlap (J) with PS emission, combined with a dual‐channel energy transfer process, with a high T1 exciplex host system to suppress the back energy transfer (BET) from PS to the host and a high intrinsic stable

One Molecular Platform, Three Distinct Narrowband Organoboron TADF Emitters: A Divergent One-Pot Strategy From Green to Red. [PDF]

open access: yesAngew Chem Int Ed Engl
One platform–three emitters: Divergent one‐pot borylation of a single indolocarbazole platform exploits competing mono‐ and double‐borylation pathways to generate three spectrally distinct organoboron MR‐TADF emitters spanning green to red, enabling color‐tunable narrowband OLEDs with external quantum efficiencies over 30%.
