One Molecular Platform, Three Distinct Narrowband Organoboron TADF Emitters: A Divergent One‐Pot Strategy From Green to Red

Angewandte Chemie, EarlyView.
One platform–three emitters: Divergent one‐pot borylation of a single indolocarbazole platform exploits competing mono‐ and double‐borylation pathways to generate three spectrally distinct organoboron MR‐TADF emitters spanning green to red, enabling color‐tunable narrowband OLEDs with external quantum efficiencies over 30%.

Hierarchically engineered electrocatalysts for durable oxygen reduction in zinc–air batteries

AIChE Journal, EarlyView.
Abstract Rechargeable zinc–air batteries (ZABs) are promising energy storage systems but are limited by sluggish oxygen reduction reaction (ORR) kinetics at the air cathode. Herein, we report hierarchically engineered cobalt tetraaminophthalocyanine/MXene (CoPc/MXene) electrocatalysts prepared via cetyltrimethylammonium bromide‐mediated self‐assembly ...

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol

Angewandte Chemie, EarlyView.
A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Toward Predictable Nanomedicine: Current Forecasting Frameworks for Nanoparticle–Biology Interactions

Advanced Intelligent Discovery, EarlyView.
Predictive models successfully screen nanoparticles for toxicity and cellular uptake. Yet, complex biological dynamics and sparse, nonstandardized data limit their accuracy. The field urgently needs integrated artificial intelligence/machine learning, systems biology, and open‐access data protocols to bridge the gap between materials science and safe ...

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

Angewandte Chemie, EarlyView.
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 ...

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...
