(E)-1-(2,4-Dinitrophenyl)-2-(3-ethoxy-4-hydroxybenzylidene)hydrazine

open access: yesActa Crystallographica Section E, 2014
The molecule of the title hydrazine derivative, C15H14N4O6, is essentially planar, the dihedral angle between the substituted benzene rings being 2.25 (9)°. The ethoxy and hydroxy groups are almost coplanar with their bound benzene ring [r.m.s. deviation

Secondary Coordination Sphere‐Directed Design of Thermo‐Responsive and Bright Luminescent Manganese(II) Complexes

open access: yesAdvanced Optical Materials, EarlyView.
Luminescent manganese(II) complexes with modified secondary coordination spheres exhibit remarkably high emission quantum yields and distinct chromic behavior. The introduction of steric and functional groups enhances emission efficiency and enables temperature dependent emission color changes through reversible intramolecular interactions in the ...

Synthesis of Polycyclic Oxazolinium Compounds from Aryloxazolines and Alkynes via Dual Photoredox/Gold Catalysis and Rhodium Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A series of polycyclic oxazolinium compounds is synthesized from various aryloxazolines with silyl‐substituted alkynes and internal alkynes via dual photoredox/gold catalysis and Rh‐catalyzed C–H bond functionalization, and affords silyl‐substituted polycyclic oxazoliniums and polycyclic oxazoliniums, respectively.

5,7‐Membered Cyclometallated Gold(III) Complexes with Pyridine‐Phenyl‐Oxazoline N^C^N Ligands as Catalysts for Organic Transformation Reactions Under Silver‐Free Conditions

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A series of 5,7‐membered cyclometallated gold(III) complexes with N^C^N tridentate ligands are prepared via transmetalation of pyridine‐phenyl‐oxazoline ligand‐containing organomercury compounds with potassium gold(III) chloride (KAuCl4) for catalysis.

CO2‐to‐Cyclic Carbonate Transformation at Ambient Pressure Using a Mechanochemically Prepared Ti(III) Catalyst

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A Ti(III) complex synthesized mechanochemically catalyzes the cycloaddition of CO2 (1 bar) with terminal, internal, and trisubstituted epoxides. Mechanistic studies by density functional theory calculations reveal that the superior activity of Ti(III) compared to Ti(IV) arises from its lower oxophilicity, facilitating CO2 insertion into Ti–O bonds, as ...

On the Role of MWCNTs for the Effective Detection of Glucose Using MWCNTs/NiO/MWCNTs Stacks on Carbon Paper Electrodes

open access: yesAdvanced Sensor Research, EarlyView.
This study deciphers the mechanism of enhanced glucose detection using multiwalled carbon nanotubes and nickel oxide stacks (MWCNTs/NiO/MWCNTs) on commercially available carbon paper electrodes. We demonstrate the role of MWCNTs where the defects enrich the electrocatalytic activity when they come in contact with the glucose molecule for its selective ...

Human Nervous System‐Based Biohybrid Robot‐On‐A‐Chip with Sensing Function for Toxicity Screening

open access: yesAdvanced Science, EarlyView.
Human nervous system‐based biohybrid robot‐on‐a chip with eye function as sensing system in addition to brain/motor neuron/muscle functions is proposed. Upon light stimulation, the eye assembloid generates electrophysiological signals, which are transmitted through the cerebral organoid and motor neuron spheroid, inducing muscle movement.

STING COPII ER Export Trafficking and Signaling Primed by Phosphorylation Switches

open access: yesAdvanced Science, EarlyView.
This schematic outlines STING trafficking and signaling via coat protein II (COPII)‐mediated endoplasmic reticulum (ER) export. Following cyclic GMP‐AMP (cGAMP) stimulation, TANK‐binding kinase 1 (TBK1) activates on COPII vesicles, partially dissociating into the cytosol to phosphorylate ER‐localized STING, creating pSGME/pFS COPII‐sorting motifs ...
