The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

Advanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

Monomers for thermosetting and toughening epoxy resins [PDF]

Eight glycidyl amines were prepared by alkylating the parent amine with epichlorohydrin to form chlorohydrin, followed by cyclization with aqueous NaOH. Three of these compounds contained propargyl groups with postcuring studies.

Oxalates as Activating Groups for Alcohols in Visible Light Photoredox Catalysis: Formation of Quaternary Centers by Redox-Neutral Fragment Coupling. [PDF]

, 2015
Alkyl oxalates are new bench-stable alcohol-activating groups for radical generation under visible light photoredox conditions. Using these precursors, the first net redox-neutral coupling of tertiary and secondary alcohols with electron-deficient ...

Multidimensional Perovskite Solar Cells: What's Next after 3D/2D?

Advanced Energy Materials, EarlyView.
The frontier of low‐dimensional/3D perovskite interfaces is explored, moving beyond the well‐established 2D/3D interfaces. This discussion underscores the potential of combining 1D and 0D perovskites with the 3D structure, showcasing new prospects and challenges in material design. This reveals the pivotal role of the molecular structure of the organic

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Dopant Deuteration Enables Long‐lived Room‐temperature Phosphorescence

Aggregate, EarlyView.
This study explores the impact of deuteration on organic host–guest doped systems, achieving prolonged room‐temperature phosphorescence lifetimes and enhanced quantum yields. By suppressing non‐radiative decay and enhancing intersystem crossing, deuterated emitters enable tunable ultralong afterglow, offering insights into isotope effects and potential

Synthesis of Adenine Nucleosides with a Reactive (β-Iodovinyl)sulfone or (β-Keto)sulfone Group at the C2 Position and Their Polymerase-Catalyzed Incorporation into DNA

Molecules
Iodosulfonylation of an ethynyl group at the C2 position of 2′-deoxyadenosine or adenosine with TsI provides (E)-2-(β-iodovinyl)sulfones. The latter undergo nucleophilic substitution with amines via an addition–elimination to give β-sulfonylvinylamines ...
