Label‐free Electrochemiluminescence Imaging of Single‐Cell Adhesions Using Bipolar Nanoelectrode Array

A label-free and fast approach for positive electrochemiluminescence (ECL) imaging of single cells by bipolar nanoelectrode array is proposed. The reduction of oxygen at a platinized gold nanoelectrode array in a closed bipolar electrochemical system is coupled with an oxidative ECL process at the anodic side. For elevating the ECL imaging contrast...

Two faces of the same coin: coupling X‐ray Absorption and NMR spectroscopies to investigate the exchange reaction between prototypical Cu coordination complexes

The satisfactory rationalization of complex reactive pathways in solution chemistry may greatly benefit from the combined use of advanced experimental and theoretical complementary methods of analysis. In this work, we combine X-Ray Absorption and 1 H-NMR spectroscopies with state-of-the-art Multivariate Curve Resolution and theoretical analyses to...

Missing Member in the MIIMIIISi4N7 Compound Class: Carbothermal Reduction and Nitridation Synthesis Revealing Substitution of N by C and O in CaLu[Si4N7−2xCxOx]:Eu2+/Ce3+ (x ≈ 0.3)

The nitridosilicate CaLu[Si 4 N 7−2 x C x O x ] ( x ≈ 0.3) was synthesized by carbothermal reduction and nitridation starting from CaH 2 , Lu 2 O 3 , graphite and amorphous Si 3 N 4 at 1550°C using a radiofrequency furnace. CaLu[Si 4 N 7−2 x C x O x ] ( x ≈ 0.3) crystallizes isotypic to many previously known M II M...

A Ferroelectric Metallomesogen Exhibiting Field‐Induced Slow Magnetic Relaxation

Magnetoelectric (ME) materials exhibiting coupled electric and magnetic properties are of significant interest because of their potential use in memory storage devices, new sensors or low-consumption devices. Herein, we report a new category of ME material that shows liquid crystal (LC), ferroelectric (FE), and single molecule magnet (SMM) behaviors....

Direct superacid‐promoted difluoroethylation of aromatics

Under superacid conditions, aromatic amines are directly and regioselectively 1,1-difluoroethylated. Low temperature in situ NMR studies confirmed the presence of benzylic α -fluoronium and α -chloronium ions as key intermediates in the reaction. This method has a wide substrate scope and can be applied to the late-stage functionalization of natural...

Perovskite Light‐Emitting Electrochemical Cells Employing Electron Injection/Transport Layers of Ionic Transition Metal Complexes

The optimized external quantum efficiency (EQE) of the proposed LEC reaches 6.8 %, which is among the highest values for perovskite LECs reported so far. This work successfully demonstrates that separating the ion transport, electron injection and transport layer from the perovskite emissive layer is more effective in adjusting device carrier balance...

Regioselective Magnesiation and Zincation Reactions of Aromatics and Heterocycles Triggered by Lewis Acids

Switch at Will: The functionalization of aromatics and heterocycles by using Zn- or Mg-TMP (TMP=2,2,6,6-tetramethylpiperidyl) bases has been widely explored. In many cases, a full switch of regioselectivity can be achieved in the presence of a Lewis acid additive. Also, these methods are compatible with continuous flow setups allowing the use of highly...

Thermotriggered Domino‐like Single‐Crystal‐to‐Single‐Crystal Phase Transition from Face‐to‐Edge to Face‐to‐Face Packing of Anthracenes

Vis-à–vis going green Thermal stimuli induced the single-crystal-to-single-crystal phase transition of the blue-PL face-to-edge packed 1,8-bisphenylanthracene crystal, which experienced spontaneous propagation of the face-to-face molecular packed greenish-blue-PL crystal. Abstract Stimuli-triggered crystal-to-crystal and single-crystal-to-single-crystal...

Ligand‐Controlled Regiodivergence for Catalytic Stereoselective Semireduction of Allenamides

A palladium-catalyzed, ligand controlled regiodivergent semireduction of allenamides has been developed. This phosphine ligand-switched semireduction system has enabled an easy access to a broad scope of allylic and vinylic amides by using a single palladium catalyst. The excellent regio- and stereoselectivities of the divergent processes were achieved...
