Cation‐π Interaction‐Based Biointerface for Low‐Cost PD‐1 Detection Toward NSCLC Immunotherapy Monitoring

Advanced Materials Interfaces, EarlyView.
A cation‐π interaction‐based biointerface is engineered on a CNT‐FET for label‐free detection of PD‐1. PD‐1 monoclonal antibodies are orientedly immobilized via cation‐π interactions between PCz‐wrapped semiconducting single‐walled carbon nanotubes and the Fc region of the monoclonal antibody.

Ultrathin and Flexible Organic Light‐Addressable Potentiometric Sensors

Advanced Materials Technologies, EarlyView.
The first ultrathin, fully organic, and flexible light‐addressable potentiometric sensor (LAPS) is demonstrated. With a thickness of only 2.3–2.9 µm, this standalone film offers sensitivity to electrolyte potential and stable performance for over 170 days.

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

Advanced Optical Materials, EarlyView.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...

Temperature Correction in a Single Luminophore Pressure‐Sensitive Paint Using a Dual‐Emitting Gold Acridine Complex

Advanced Optical Materials, EarlyView.
The use of pressure‐sensitive luminescent molecules to quantify surface pressure in wind tunnel testing has revolutionized experimental aerodynamics. This work develops a dual‐emitting gold acridine complex for the simultaneous sensing of pressure and temperature independently of each other.

Operando Electrochemical Formation of Integrated Ni‐Fe Oxyhydroxide Anode for Durable Anion Exchange Membrane Water Electrolyzer

Advanced Science, EarlyView.
The interfacial stability and activity of Ni‐Fe‐based AEMWE anodes can be directly enhanced by operando voltage‐cycling in a FeOOH‐containing electrolyte. This process simultaneously induces Ni oxidation and Fe incorporation, forming an integrated, porous (Fe, Ni)OOH layer with high conductivity and durability.

Metal (n+1)p‐nd Orbital Hybridization and Excited‐State Metal–Ligand π‐Interactions Enable d10 Carbene‐Metal‐Amide TADF OLEDs with High Efficiency and Long Operational Lifetime

Advanced Science, EarlyView.
We elucidate the key roles of metal p‐d orbital hybridization, excited‐state metal–ligand π‐interactions, and structural rotation in TADF of d10 CMA complexes. Introducing electron‐withdrawing or π‐extended ligand substituents weakens excited‐state metal‐ligand π‐interactions and improves kTADF, but may compromise emitter stability in device operation.

Palladium-catalyzed synthesis of N-arylated carbazoles using anilines and cyclic diaryliodonium salts

Beilstein Journal of Organic Chemistry, 2013
The direct synthesis of N-arylated carbazoles through a palladium-catalyzed amination of cyclic iodonium salts with anilines is described. In particular, electron-poor aniline derivatives reacted smoothly with only 5 mol % of Pd(OAc)2 as catalyst to give
