Narrowband Macrocycles: A New Paradigm for High‐Color‐Purity Organic Light‐Emitting Diodes

FlexTech, Volume 2, Issue 1, Page 34-43, June 2026.
This graphical abstract illustrates two key strategies for constructing macrocyclic multi‐resonance (MR) emitters for high‐performance OLEDs: (1) the covalent assembly of MR moieties onto macrocyclic scaffolds, and (2) the local multi‐resonance strategy within the macrocyclic backbone.

Blue‐hazard‐free single‐emissive‐layer white organic LEDs based on an anti‐quenching narrowband blue emitter

FlexMat, Volume 3, Issue 2, Page 219-227, June 2026.
A blue‐hazard‐free single‐emissive‐layer white OLED is realized using an anti‐quenching multiple‐resonance TADF emitter, BNCT. By integrating a sterically protected MR core with efficient energy transfer capability, BNCT enables warm‐white emission with high efficiency, negligible hazardous blue photons, and a simplified device architecture for next ...

The degradation mechanism of multi-resonance thermally activated delayed fluorescence materials

Nature Communications
1,4-Azaborine-based arenes are promising electroluminescent emitters with thermally activated delayed fluorescence (TADF), offering narrow emission spectra and high quantum yields due to a multi-resonance (MR) effect. However, their practical application

Effect of the Imidazole π‐Extension on TADF Emitters in Electrochemiluminescence

Chemistry – An Asian Journal
AbstractAlready known molecules which exhibit good electrochemiluminescence (ECL) efficiencies and high photoluminescence quantum yields (PLQY) have been structurally modified in order to increase their performance. The followed strategy is to stiffen the structures to limit the rotational and vibrational freedom degrees and favour radiative decay ...

3D‐Printed Optical Volatile Organic Compound Sensors Based on Donor‐Substituted Coumarin Thermally Activated Delayed Fluorescence Emitters

Small Science, Volume 6, Issue 6, June 2026.
Donor–acceptor coumarin emitters displaying thermally activated delayed fluorescence (TADF) are formulated into photocurable resins and processed by digital light processing (DLP) 3D printing. The resulting printed materials show a sensitive and repeatable photoluminescence response when exposed to volatile organic compounds (VOCs).
