An Alternative Host Material for Long‐Lifespan Blue Organic Light‐Emitting Diodes Using Thermally Activated Delayed Fluorescence

open access: yesAdvanced Science, 2017
It has been challenging to find stable blue organic light emitting diodes (OLEDs) that rely on thermally activated delayed fluorescence (TADF). Lack of stable host materials well‐fitted to the TADF emitters is one of the critical reasons.

Conformational isomerization: A novel mechanism to realize the AIE‐TADF behaviors

open access: yesAggregate, 2023
Thermally activated delayed fluorescence (TADF) materials with aggregation‐induced emission (AIE) features can overcome aggregation‐caused quenching (ACQ) and emit intensely in aggregate states and thus have attracted enormous attention in the fields of ...

Organophosphides: A New Class of Luminophore Ligands for Copper(I) Carbene Based TADF Emitters and Photocatalysts. [PDF]

open access: yesAngew Chem Int Ed Engl
Dimesitylphosphide as a heavier congener of established amide ligands for charge‐transfer copper(I) complexes leads to bathochromic shift of the emission by up to 3645 cm−1 into the orange‐red (solid, polymer films) and even NIR (solution). The thermally activated delayed fluorescence exhibits high dissymmetry factors of glum = 10−2 in polystyrene.

Inverting Singlet and Triplet Excited States using Strong Light-Matter Coupling

open access: yes, 2019
In organic microcavities, hybrid light-matter states can form with energies that differ from the bare molecular excitation energies by nearly 1 eV. A timely question, given recent advances in the development of thermally activated delayed fluorescence ...

Open questions on the photophysics of thermally activated delayed fluorescence

open access: yesCommunications Chemistry, 2021
The process of thermally activated delayed fluorescence (TADF) converts non-radiative triplet states into emissive singlet states. Herein we outline the fundamentals of TADF, some of the recent progress in understanding the key material properties ...

Omni-Lie 2-algebras and their Dirac structures [PDF]

open access: yes, 2011
We introduce the notion of omni-Lie 2-algebra, which is a categorification of Weinstein's omni-Lie algebras. We prove that there is a one-to-one correspondence between strict Lie 2-algebra structures on 2-sub-vector spaces of a 2-vector space $\V$ and ...

Ultrafast Structure and Dynamics in the Thermally Activated Delayed Fluorescence of a Carbene-Metal-Amide [PDF]

open access: yes, 2018
Thermally activated delayed fluorescence has enormous potential for the development of efficient light emitting diodes. A recently discovered class of molecules (the carbene – metal – amides, CMAs) are exceptionally promising as they combine the small ...

Solution processable small molecule based TADF exciplex OLEDs [PDF]

open access: yesOrganic Electronics, 2018
Abstract In this work we report the optimisation of the solution processable TADF exciplex emitter in OLED devices formed by the small molecules 9-[2,8]-9-carbazole-[dibenzothiophene-S,S-dioxide]-carbazole (DCz-DBTO2) and 4,4′-cyclohexylidenebis[N,N-bis(4-methylphenyl)benzenamine] (TAPC). This exciplex, previously reported by Jankus et al.
