An In-Depth Quantum Chemical Investigation of INVEST TADF Dyes
The Journal of Physical Chemistry LettersThe design of organic emitters with inverted singlet-triplet (INVEST) gaps presents a promising route to enhance triplet harvesting in optoelectronic applications, yet reliable descriptors for predicting this phenomenon remain scarce. Here, we introduce a wavefunction-based descriptor, Q_a^t, derived from the transition density matrix, to quantify the ...

Employing organic donor-acceptor thermally activated delayed fluorescence (TADF) compounds as photocatalysts [PDF]
This thesis aims to expand the range of donor-acceptor (D-A) thermally activated delayed fluorescence (TADF) compounds trialled as photocatalysts (PCs), as well as increasing mechanistic understanding of photocatalytic processes.

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation
Angewandte Chemie International Edition, EarlyView.Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.

TADF mechanism in a carbene-copper emitter: Insights from the nuclear ensemble simulations [PDF]
We use the nuclear ensemble approach to study the mechanism of thermally activated delayed fluorescence (TADF) in a carbene-copper-amide (CMA1) emitter.

Fluorene vs. Spirobifluorene: Effect of the π-system on TADF properties [PDF]
There are many options to design a molecular structure that could result in thermally activated delayed fluorescence (TADF). One promising strategy is to use donor-π-acceptor motive where the electron-donating unit is linked to the electron-acceptor via ...

Studies on Photophysical Properties of Chiral TADF [PDF]
, 2023 학위논문(석사) -- 서울대학교대학원 : 공과대학 재료공학부, 2023. 2. 권민상.A light emitting phenomenon of singlet state by transitioning to a ground state is called fluorescence. Since fluorescence can fundamentally only harvest energy from the singlet states, which make up 25% of

A Novel Carbazolophane: A Comparison of the Performance of Two Planar Chiral CP-TADF Emitters [PDF]
The prototypical example of a (cyclo)phane, [2.2]paracyclophane (PCP), has proven to be a versatile stereogenic moiety within the design of circularly polarized thermally activated delayed fluorescence (CP-TADF) emitters; however, the exploration of ...

Chemistry – A European Journal, EarlyView.A comprehensive experimental and theoretical study is presented of a family of TADF dyes. Comparing the behavior of structurally related dyes, we uncover the subtle and somewhat unexpected role of conformational degrees of freedom associated with peripheral groups that affect the delicate interplay of excited states that governs spin–orbit coupling ...
