Spectral Assignment in the [3 + 2] Cycloadditions of Methyl (2E)-3-(Acridin-4-yl)-prop-2-enoate and 4-[(E)-2-Phenylethenyl]acridin with Unstable Nitrile N-Oxides

Molecules
The investigation of cycloaddition reactions involving acridine-based dipolarophiles revealed distinct regioselectivity patterns influenced mainly by the electronic factor. Specifically, the reactions of methyl-(2E)-3-(acridin-4-yl)-prop-2-enoate and 4-[(

Optimization of Adsorption Sites for Selective Hydrobenzoin and Syngas Production in a Single Photoredox Cycle

Advanced Energy Materials, EarlyView.
Efficient C─C coupling hydrobenzoin production and tunable syngas generation via benzyl alcohol oxidation and CO2 reduction is realized by Ni2P/CdS composite in a single photoredox cycle. In situ and ex situ characterizations, along with theoretical calculations, reveal that the active site optimization facilitates intermediate formation and desorption.

Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

Advanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.

Synthesis of Versatile DNA‐Conjugated Aldehydes by Controlled Oxidation of Amines

Angewandte Chemie, EarlyView.
A controlled oxidation strategy enables efficient in situ generation of aldehyde‐functionalized DNAs from DNA‐conjugated amines using O2/laccase/TEMPO. This approach facilitates reversible amine–aldehyde transformations for DNA bioconjugation, and provides access to chemically diverse DNA‐encoded libraries, broadening the toolbox for chemical biology ...

Heterogeneous Photocatalytic Dehydrogenative Cross‐Coupling and Addition Reaction with Metal‐Loaded Titanium Oxide Photocatalysts

Advanced Energy and Sustainability Research, EarlyView.
Heterogeneous photocatalysis with metal‐loaded TiO2 photocatalysts under mild conditions can be utilized for various dehydrogenative cross‐coupling reactions, including the functionalization of aromatic rings via radical addition‐elimination or radical–radical coupling mechanisms, and the radical anti‐Markovnikov addition of alkenes. In some cases, the

Elucidating Ligand Exchange Dynamics of Hexacyanochromate‐Based Redox Mediators in Aqueous Iron‐Chromium Redox Flow Batteries

Angewandte Chemie, EarlyView.
The ligand exchange between cyanide and hydroxide in hexacyanochromate negolyte was caused by the disruption of coordination environment of the redox mediator ([Cr(CN)6]4‐/3−), with a critical factor as an elevated pH during electrochemical cycle. To mitigate this electrolyte co‐modulation strategy is introduced, optimizing the [OH−]/[CN−] ratios ...
