TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Crystallization‐Induced Emission Enhancements of Hybrid Butenolide‐Diphenylethenes

Chemistry – A European Journal, EarlyView.
Hybrid butenolide‐diphenylethene fluorophores show crystallization‐induced emission enhancement (CIEE), with substituents tuning solid‐state quantum yields up to 50%. One derivative, BuCM, displays dual‐state emissions (DSE), making this compact scaffold a promising platform for CIEE/DSE‐active fluorophores.

Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

FlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

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

FlexMat, 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 ...

Conjugation‐Length Dependent Interplay Between Charge Transfer and Locally Excited States in Sequence‐Defined Donor–Acceptor Substituted Oligo(Phenylene Ethynylene)s

Macromolecular Rapid Communications, EarlyView.
Iterative synthesis gives access to sequence‐defined oligo(para‐phenylene ethynylene)s, bridging donor and acceptor units through stepwise extension of the conjugated backbone. Accurate length control enables systematic structure‐property relationship investigations across absorption, emission, and excited‐state dynamics.

A green solvent processable, self‐doped N‐annulated perylene butyl tetraester applied as a solar cell cathode interlayer

Polymer International, EarlyView.
A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene
