Study of Phenoxaborin Derivatives for Thermally Activated Delayed Fluorescence Emitters
Journal of Nanoscience and Nanotechnology, 2018Novel thermally activated delayed fluorescence (TADF) materials including 10H-phenoxaborin (PXB) as an electron acceptor and carbazole derivatives [carbazole (Cz), 1-methyl-carbazole (1-m-Cz), and 3,6-bis(3,6-diphenylcarbazolyl)carbazole (BDPCC)] as electron donors (Cz-PXB, 1-m-Cz-PXB, and BDPCC-PXB) were designed and investigated theoretically for ...

Thermally activated delayed fluorescence with circularly polarized luminescence characteristics
Chemical Communications, 2015A 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.

Mechanism of Intersystem Crossing of Thermally Activated Delayed Fluorescence Molecules
The Journal of Physical Chemistry A, 2015The spin sublevel dynamics of the excited triplet state in thermally activated delayed fluorescence (TADF) molecules have not been investigated for high-intensity organic light-emitting diode materials. Understanding the mechanism for intersystem crossing (ISC) is thus important for designing novel TADF materials.

Cascade Effect of a Dimerized Thermally Activated Delayed Fluorescence Dendrimer
Angewandte ChemieAbstractThermally activated delayed fluorescence (TADF) emitters with a high horizontal orientation are highly essential for improving the external quantum efficiency (EQE) of organic light‐emitting diodes; however, pivotal molecular design strategies to improve the horizontal orientation of solution‐processable TADF emitters are still scarce and ...

Photocatalytic Mechanisms of Organic Thermally Activated Delayed Fluorescence Compounds
The Journal of Physical Chemistry LettersReverse 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 ...
