Difluoroboron-Enabled Thermally Activated Delayed Fluorescence
ACS Applied Materials & Interfaces, 2019A new series of tetracoordinated boron-enabled thermally activated delayed fluorescence (TADF) materials with a donor-acceptor BF2-type framework were designed and conveniently synthesized. Difluoroboron plays a critical role and acts as a key to coordinate with the latent acceptor of the 2-(4-phenylpyridin-2-yl)phenol (PPyPOH) moiety to realize TADF ...

Thermally Activated Delayed Fluorescent Polymers
Journal of Polymer Science Part A: Polymer Chemistry, 2017ABSTRACTThe development of organic light emitting diodes (OLEDs) based on fluorescent materials has made a great progress in improving light emitting efficiency and full range colors. But it still encounters the low singlet excitons generation ratio of 25% in device.

AbstractA novel molecular design approach transforming nonthermally activated delayed fluorescence (TADF) molecules to TADF molecules is developed for high external quantum efficiencies in TADF devices by utilizing an opened double emission process through selective twisting of the donor structure. Two non‐TADF type donor–acceptor molecules are coupled

Thermally Activated Delayed Fluorescence via Triplet Fusion
The Journal of Physical Chemistry Letters, 2019Manipulating triplet states is technically intriguing for organic semiconductors and photochemical conversion. Sensitized photon upconversion that converts low-energy photons into higher-energy ones via triplet fusion holds great potential in augmentation of photovoltaic devices and photocatalysis. Conventional requirement of exothermic triplet-triplet

A study of thermally activated delayed fluorescence in C60
Chemical Physics Letters, 1997The existence of thermally activated delayed fluorescence in C is demonstrated by the study of the temperature 60 . dependence 291-353 K of the fluorescence intensity of C degassed solutions. The determined singlet-triplet energy gap, 60 35" 2k J rmol, agrees with the value calculated from previously reported fluorescence and low temperature phospho- .

Thermally Activated Delayed Fluorescence from Pentacarbazorylbenzonitrile
Chemistry Letters, 2016A benzonitrile derivative substituted by five carbazoles (5CzBN), which emits thermally activated delayed fluorescence (TADF), was synthesized and evaluated. The organic light-emitting diode (OLED) containing 5CzBN demonstrated light-blue electroluminescence and a high external quantum efficiency of 14.8%.

Nido‐Carboranes: Donors for Thermally Activated Delayed Fluorescence
Angewandte Chemie, 2018AbstractAn approach to the design of nido‐carborane‐based luminescent compounds that can exhibit thermally activated delayed fluorescence (TADF) is proposed. 7,8‐Dicarba‐nido‐undecaboranes (nido‐carboranes) having various 8‐R groups (R=H, Me, i‐Pr, Ph) are appended to the meta or para position of the phenyl ring of the dimesitylphenylborane (PhBMes2 ...
