o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

open access: yesFlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...

Small-molecule ligands strongly affect the Förster resonance energy transfer between quantum dot and fluorescent protein

open access: yes, 2011
We report herein the study of the Förster resonance energy transfer (FRET) between a CdSe/ZnS core/shell quantum dot (QD) capped with three different small-molecule ligands, 3-mercaptopropionic acid (MPA), glutathione (GSH), and dihydrolipoic acid (DHLA),

Counter‐ion modulation: A facile approach toward quenching‐resistant multi‐resonance emitters for efficient narrowband electroluminescence

open access: yesFlexMat, EarlyView.
Quenching‐resistant carbocation‐based multi‐resonance emitters are developed via a facile counter‐ion modulation strategy, giving much narrowed emission bands under high doping concentrations, and greatly improved device efficiency for solution‐processed narrowband OLEDs by simply increasing the size of counter ions.

Rigid polymer matrix enables direct red afterglow from rhodamine dyes without energy transfer

open access: yesFlexMat, EarlyView.
This work presents a universal and facile strategy to achieve direct red room‐temperature phosphorescence from commercial rhodamine dyes by harnessing the superior rigid confinement of a novel phosphorus‐containing polymer (DOBP), effectively bypassing the complex TS‐FRET process.

Pyridine‐dicarbonitriles acceptor engineering in multi‐resonance thermally activated delayed fluorescence with hybridized short‐ and long‐range charge transfer for high‐performance electroluminescence

open access: yesFlexMat, EarlyView.
Pyridine‐dicarbonitrile units integrated into a multiple‐resonance core engineer the excited state through cooperative short‐range charge transfer (SRCT) and long‐range charge transfer (LRCT), thereby enhancing the spin‐flipping process. Abstract Multi‐resonance (MR) thermally activated delayed fluorescence (TADF) materials exhibit narrowband emission ...

Regulating electronic coupling and molecular vibration to facilitate exciton transfer of fused ring electron acceptors enables 20.66% efficiency of organic solar cells

open access: yesInfoMat, EarlyView.
Introducing L8‐F efficiently reinforces electronic coupling and suppresses molecular vibration for L8‐BO:L8‐F to afford ultra‐fast exciton transfer rate and thus prolonged exciton diffusion length. Therefore, D18:L8‐BO:L8‐F based organic solar cells (OSCs) acquire more efficient exciton dissociation and weaker charge carrier recombination to achieve an
