Novel Crown Ether-Functionalized Fusidic Acid Butyl Ester: Synthesis, Biological Evaluation, In Silico ADMET, and Molecular Docking Studies

Molecules
Crown ethers have gained importance in the field of medicine because of their resemblance to natural ionophores like valinomycin. With the goal of developing new pharmacologically important crown ethers, a novel series of crown ethers linked with Fusidic

Light‐Enhanced Chloride Transport by Thiourea‐Appended Molecular Motor

Angewandte Chemie, EarlyView.
A molecular motor functionalized with a thiourea anion‐binding motif mediates transmembrane chloride transport. Light irradiation enhances transport efficiency by populating a more active metastable isomer, which slowly equilibrates to the initial stable isomer.

Deprotonation and Alkylation of Weakly Acidic C(sp3)─H Bonds Through In Situ Generation of a Strong Hydride Base From 1,1,3,3‐Tetramethyldisiloxane and Potassium tert‐Butoxide

Angewandte Chemie, EarlyView.
The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...

Geometric and Electronic Structures of Ag⁺(benzo-18-crown-6), Ag⁺(dibenzo-18-crown-6), and Ag⁺(dibenzo-15-crown-5) Complexes Investigated by Cold Gas-Phase Spectroscopy

, 2019
The UV photodissociation (UVPD) spectra of Ag+ complexes with benzo-18-crown-6 (B18C6), dibenzo-18-crown-6 (DB18C6), and dibenzo-15-crown-5 (DB15C5) [Ag+(B18C6), Ag+(DB18C6), and Ag+(DB15C5)] are observed under cold gas-phase conditions.

High‐Efficiency Deep Blue Single‐Gaussian Europium(II) Emitters and Their Emitter‐Host Interactions

Advanced Functional Materials, EarlyView.
Crown‐ether ligands and carborate anions enable vacuum‐processable Eu(II) emitters with efficient single‐Gaussian deep‐blue luminescence. Combined photophysical and computational analyses reveal that excited‐electron confinement and steric shielding of the europium center jointly govern compatibility with OLED host materials, establishing molecular ...

Photovoltaic Stimulation of Mouse and Pig Retina With Pyrolytic Carbon Microelectrodes Integrated on High‐Density Silicon Solar Cell Arrays

Advanced Healthcare Materials, EarlyView.
In this study, we fabricate photovoltaic retinal implants with pyrolytic carbon electrodes and test their ability to stimulate mouse and pig retinas when illuminated with near‐infrared light. We find increased spiking activity in both animal models compared to spontaneous activity and TTX controls and analyze the spike amplitude, latency and frequency.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.
