Switchable Site-Selective Benzanilide C(sp²)-H Bromination via Promoter Regulation

Molecules
Regioselective benzanilide bromination that generates either regioisomer from the same starting material is desirable. Herein, we develop switchable site-selective C(sp2)-H bromination by promoter regulation.

High‐Performance Ternary Organic Solar Cells via Isomeric Engineering of Nonfullerene Guest Acceptors

Advanced Science, EarlyView.
Two isomeric nonfullerene acceptors, BTP‐γ‐Br and BTP‐δ‐Br, were designed to investigate their effects on the optoelectronic properties and photovoltaic performance of ternary blends. Incorporating BTP‐γ‐Br into the D18:N3 binary system can enhance film crystallinity and suppress charge recombination, achieving a high PCE of 19.2% and a certified JSC ...

Polyglycerol coated polypropylene surfaces for protein and bacteria resistance [PDF]

, 2015
Polyglycerol (PG) coated polypropylene (PP) films were synthesized in a two- step approach that involved plasma bromination and subsequently grafting hyperbranched polyglycerols with very few amino functionalities.

SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

Advanced Science, EarlyView.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides

Advanced Science, EarlyView.
This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...

A Search for Blues Brothers: X-ray Crystallographic/Spectroscopic Characterization of the Tetraarylbenzidine Cation Radical as a Product of Aging of Solid Magic Blue [PDF]

, 2016
Magic blue (MB+˙ SbCl6− salt), i.e. tris-4-bromophenylamminium cation radical, is a routinely employed one-electron oxidant that slowly decomposes in the solid state upon storage to form so called ‘blues brothers’, which often complicate the quantitative

Oxidative bromination and oxidation of organic substrates catalyzed by bis2,2'-hydroxyphenylbenzimidazoleFe(III) complex entrapped in zeolite-Y cavity [PDF]

, 2017
BACKGROUND: Zeolite encapsulated transition metal complexes have proven to be better catalysts for most organic transformations as they share advantages of both homogeneous and heterogeneous catalysts because the complex inside the zeolite cage can move ...
