Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly

Advanced Science, EarlyView.
In this study, hydrophobic tripeptides are explored as building blocks for stable piezoelectric crystals. Tripeptides with phenylalanine at the central position self‐assembled into uniform, thermally stable crystals. Piezoresponse force microscopy reveals a high effective piezoelectric coefficient of 24.0 pC N−1, attributed to asymmetric molecular ...

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

A Most Unusual Zeolite Templating: Cage to Cage Connection of One Guest Molecule [PDF]

, 2010
An unusual case of a diquaternary ammonium dication, with large bulky end groups built from the tropane moiety and connected by a C4 methylene chain, is found to reside in zeolite SSZ-35 (STF).

Chaperone‐Mediated Autophagic Degradation of USP9X in Macrophages Exacerbates Postmyocardial Infarction Inflammation and Cardiac Dysfunction

Advanced Science, EarlyView.
This study demonstrates that inflammatory stimuli induce the acetylation‐triggered, chaperone‐mediated autophagic degradation of ubiquitin‐specific peptidase 9 X‐linked (USP9X) in macrophages. USP9X acts as a macrophage “inflammation switch” after myocardial infarction (MI). USP9X loss destabilizes tumor necrosis factor receptor‐associated factor (TRAF)

Copper‐Catalyzed Three‐Component Selective 1,4‐Amino Oxygenation of 1,3‐Dienes

Angewandte Chemie, EarlyView.
Enclosed is a copper‐catalyzed selective 1,4‐amino oxgenation of 1,3‐dienes with the presence of a strong Brønsted acid. This three‐component transformation offers a novel and powerful approach to construct (E)‐1,4‐allylic amino oxygenated motifs by the simultaneous installation of structurally diverse alkylamines and alcohols directly onto 1,3‐dienes.

Predictive, Data‐Driven Design of Red‐Light Photoredox Catalysts for C─Heteroatom Bond Formation

Angewandte Chemie, EarlyView.
From redox numbers to red light: Donor oxidation and core reduction potentials predict E0‐0 in cyanoarene dyes, guiding selection of an efficient red‐light catalyst, 4MeODPATPN (PC13). Under 620 nm light, PC13 facilitates Ni‐catalyzed C─heteroatom cross‐couplings (C─N, C─O, C─S) with high functional‐group tolerance and reduced hydrodehalogenation ...
