Thermally Activated Delayed Fluorescence from Pentacarbazorylbenzonitrile

Chemistry Letters, 2016
A 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%.

Thermally activated delayed fluorescence with circularly polarized luminescence characteristics

Chemical Communications, 2015
A metal-free aromatic compound exhibiting thermally activated delayed fluorescence as well as circularly polarized luminescence (CPL) with dissymmetry factors of 10−3 is reported. This compound shows a sign inversion between its circular dichroism signal and CPL, which is caused by a large conformational change upon photoexcitation.

Nido‐Carboranes: Donors for Thermally Activated Delayed Fluorescence

Angewandte Chemie, 2018
AbstractAn 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 ...

Photocatalytic Mechanisms of Organic Thermally Activated Delayed Fluorescence Compounds

The Journal of Physical Chemistry Letters
Reverse intersystem crossing (RISC) has become possible by minimizing the energy gap between the first excited singlet (S1) and triplet state (T1), which facilitates the thermally activated delayed fluorescence (TADF). Due to the small singlet-triplet energy gap, the S1 and T1 states exhibit comparable redox reactivity, leading organic TADF compounds ...

Thermally Activated Delayed Fluorescence Emitters for Efficient Electrochemiluminescence

ChemPhotoChem
AbstractThermally activated delayed fluorescence (TADF) materials have attracted considerable interest due to their ability to enhance electrochemiluminescence (ECL). This is achieved through the efficient upconversion of triplet excitons and the subsequent radiative transitions.
