Manganese‐Catalyzed Enantioselective Dearomative Epoxidation of Naphthalenes with Aqueous Hydrogen Peroxide

Angewandte Chemie, EarlyView.
The enantioselective epoxidation of naphthalenes into their corresponding arene oxides with aqueous hydrogen peroxide is described. The reaction combines dearomatization with installation of chemically versatile functionality in an enantioselective manner.

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Surface-enhanced Raman Spectroscopy of Benzimidazolic Fungicides: Benzimidazole and Thiabendazole [PDF]

Bulletin of the Korean Chemical Society, 2009
‡Surface-enhanced Raman Scattering (SERS) spectroscopy is applied to the study of the adsorption of benzoimidazolic fungicides benzimidazole (BIZ) and thiabendazole (TBZ) on silver mirrors. The influence of pH on the adsorption mechanism was investigated.

Cation‐Engineered Post‐Treatment for Blue Perovskite Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
This work presents a cation‐engineered post‐treatment strategy for high‐performance mixed‐halide blue PeLEDs. By investigating the role of 4‐fluorophenylethylammonium (FPEA+) versus conventional phenylethylammonium (PEA+) organic cations in post‐treatment agents, it demonstrates that FPEA+ enables superior preservation of the 3D perovskite structure ...

Liquid Coordination Polymers with Anhydrous Proton Conductivity

Angewandte Chemie, EarlyView.
Functional liquid coordination polymers near ambient conditions are prepared by introducing H3PO4 as a network modifier. This process disrupts extended coordination networks, producing a stable liquid. Liquid properties are controlled by tuning the ratio of network modifiers, resulting in anhydrous proton conductivity up to 27 mS cm−1 at 353 K and ...

Supramolecular Recognition of a DNA Four‐Way Junction by an M2L4 Metallo‐Cage, Inspired by a Simulation‐Guided Design Approach

Angewandte Chemie, EarlyView.
DNA Holliday junctions, or four‐way junctions (4WJs) are an attractive therapeutic target due to their prevalence in DNA replication and repair, and viral disease. Combining experimental and computational methods, we show that quadruple‐stranded dinuclear platinum metallo‐cages are an excellent size and shape match for the cavity of the 4WJ open ...
