Synthesis of Large‐ and Medium‐Sized Heterobiaryl Atropisomeric Rings and Atropopeptides by Catalytic Intramolecular SNAr

Angewandte Chemie, EarlyView.
Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.

Synthesis of Some Phenylpyrazolo Benzimidazolo Quinoxaline Derivatives as Potent Antihistaminic Agents

E-Journal of Chemistry, 2010
2,3-Diphenyl quinoxaline (NI) was fused with benzimidazole (NII) by a methylene bridge, which was then allowed for acetylation. The acetylated product (NIV) was made to react with different aromatic aldehydes to give chalcones (NV1-NV5).
