Water‐Soluble Luminescent Trityl Radical for Fluorescence/Magnetic Resonance Dual‐Modal Imaging Probe

Advanced Science, EarlyView.
Stable water‐soluble luminescent tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals, TTM‐trisTP3B and TTM‐trisTP9B, were designed and successfully synthesized. They exhibited deep‐red emissions and high photostability in water. TTM‐trisTP3B exhibited dual functionality as a fluorescence imaging (FI) probe and a magnetic resonance imaging (MRI) contrast ...

Condition-controlled divergent trifluoroalkylation: a diversity-oriented synthesis strategy for efficient construction of CF3-decorated carbazole libraries

BMC Chemistry
A condition-controlled divergent trifluoroalkylation strategy for carbazole derivatives has been developed via alkylation with trifluoropyruvate. Employing trifluoroacetic acid (TFA) promoter, FeCl3 catalyst, or AgSbF6 catalyst, a wide scope of mono ...

Sulfonamido-derivatives of unsubstituted carbazoles as BACE1 inhibitors [PDF]

Bioorganic & Medicinal Chemistry Letters, 2017
A novel series of variously substituted N-[3-(9H-carbazol-9-yl)-2-hydroxypropyl]-arylsulfonamides has been synthesized and assayed for β-Secretase (BACE1) inhibitory activity. BACE1 is a widely recognized drug target for the prevention and treatment of Alzheimer's Disease (AD).

Developing Metal–Polyphenol Network‐Based Single‐Protein Particle Encapsulation System for Sustained Release of Whey Protein to Mitigate Sarcopenia

Advanced Science, EarlyView.
Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.

Cavity‐Compatible Light Extraction in Top‐Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance‐Matched Narrowband Emission

Advanced Science, EarlyView.
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...

Electrochemical Control of Scholl Reaction: Arenium Cation Versus Radical Cation Pathways

Angewandte Chemie, EarlyView.
Electrochemical control of Scholl reactions allows selective access to the arenium cation and radical cation pathways via low‐potential acidic (LPA) and high‐potential neutral (HPN) conditions, respectively. This control reveals that most substrates react through both pathways, albeit with clear preferences, and provides an experimental foundation for ...

Trap‐Programmable Ruddlesden–Popper Perovskite Nanocrystals for Persistent Optoelectronic Memory and Photonic Synapses

Advanced Science, EarlyView.
This work presents trap‐programmable Ruddlesden–Popper perovskite nanocrystals for ultralong‐lived optical memory and photonic synapses. Layer‐controlled octahedral distortion modulates trap depth and carrier‐storage kinetics, enabling persistent luminescence beyond 5000 s at room temperature.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Architecting Anisotropic Force‐Responsive Bidirectional High‐Contrast Three‐Color Fluorescence Switches via Effective Molecular Modulation for High‐Security Information Storage

Advanced Science, EarlyView.
Synergistically integrating substituent variation and positional isomerism in molecular engineering affords 13 rare tricolored mechanofluorochromic luminogens, and 3 exceedingly scarce force‐triggered bidirectional high‐contrast three‐color fluorescence switches are screened out via a three‐step protocol.
