Cascade Synthesis in Water: Michael Addition/Hemiketalization/Retro‐Claisen Fragmentation Catalyzed by CatAnionic Vesicular Nanoreactor from Dithiocarbamate

N,N-didodecylammonium N,N-didodecyldithiocarbamate (AmDTC-C12C12) underwent self-assembly to form a CatAnionic vesicular nanoreactor in water. AmDTC-C12C12 can be readily prepared by condensation between N,N-didodecylamine and carbon disulfide. Previously, the cascade Michael addition/hemiketalization/retro-Claisen fragmentation was reported, but it...

Well Defined Phosphine Free Ni‐Catalyzed Dehydrogenation of Secondary Alcohols for the Synthesis of Ketones and Ketazines

In this work, we unveil a novel synthesis of bench stable Ni (II) complexes supported by tetradentate Schiff-base ligands and the complexes were devoid of any phosphine or phosphine-based ligand. These Ni-complexes were successfully applied for the dehydrogenation of secondary alcohols for ketone and ketazine syntheses. Secondary alcohols with different...

ZnO with Different Morphologies Sensitized by Metalloporphyrins as Catalysts for H2 Production by Water Splitting under Sunlight

In this work, zinc oxide with different morphologies and textural properties were prepared and sensitized with metalloporphyrins (MPs) aiming to improve its solar energy harvesting capability for H2 production by water splitting under sunlight (a 300 W Xe/Hg lamp). An anionic iron(III)porphyrin and a cationic manganese(III)porphyrin were immobilized...

Supramolecular J‐ and H‐Aggregation of Naphthalimide‐Conjugated Dipeptide in Mixed‐Solvent Systems and its Application in Cell Imaging

Solvent polarity of binary mixture directs the self-assembly patterns of core-substituted naphthalimide conjugated short-peptide residue. Dilution of the stock solution with a more polar bad solvent leads to a J-type aggregation, whereas, dilution by a less polar bad solvent helps the system to adopt an H-type aggregation pattern. The bright green...

Diphenylbutadiene Fluorescent Analogues in Sub‐Cellular Imaging and Monitoring Mitophagy

A series of donor-acceptor substituted diphenylpolyenes with solvatochromic emission and large Stokes shifts is synthesized for organelle labeling. The morpholine pendant aids in lysosomal targeting, while hydrophobicity guides the staining of lipid droplets. Real-time monitoring of lysosomal dynamics, mitophagy, stress responses, and uptake in zebrafish...

Exploring the Impact of Oxygen Vacancies in Co/Pr‐CeO2 Catalysts on H2 Production via the Water‐Gas Shift Reaction

Co/CeO2 catalysts doped with varying amounts of Pr were synthesized to explore the impact of oxygen vacancies on water gas shift catalysis, focusing on oxygen vacancy defects for CO conversion. Abstract In this study, we utilized various Pr-doped CeO2 catalysts (Pr=5, 10, 20, and 30 wt.%) as a support medium for the dispersion of cobalt (Co)...
