Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

Advanced Science, EarlyView.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

Rare‐Earth Mediated Engineering in ZnSe@ZnS:Eu3+ to Simultaneously Achieve Structural Modulation and Atomic Eu Doping Sites for X‐Ray Imaging

Advanced Science, EarlyView.
A dual hard‐base anchoring strategy was developed to synthesize ZnSe@ZnS:Eu3+ quantum dots, leveraging fluoride‐oleylamine interactions to create surface atomic Eu doping sites. By precisely tuning temperature, Eu3+ concentration, and fluoride levels, we obtain morphologies ranging from tip growth to coupled flower‐like structures.

Selenophene π‐Bridge Enables Balanced Ambipolar Transport in High‐Performance Organic Electrochemical Transistors

Advanced Science, EarlyView.
We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid

Angewandte Chemie, EarlyView.
The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐
