Angewandte Chemie, EarlyView.A bench‐stable boryl thianthrenium dication is synthesized via thianthrenation of vinyl MIDA boronate. This novel dication enables metal‐free, chemo‐, and diastereoselective late‐stage aziridination with diverse nitrogen nucleophiles. The strategic significance is further showcased by one‐pot electrochemical and asymmetric protocols and versatile ...

Asymmetric Hydride Shift Reactions Catalyzed by Chiral Aluminium Complexes
Angewandte Chemie, EarlyView.An asymmetric intramolecular hydride shift reaction has been developed that is catalyzed by Al Lewis acids in conjunction with a chiral BINOL‐derived ligand. Racemic THP substrates are transformed into cyclohexene products via an intermediate prochiral enone; which undergoes a key 1,5‐hydride shift reaction.

Advanced Science, EarlyView.In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Non-specific cellular uptake of surface-functionalized quantum dots
, 2010 We report a systematic empirical study of nanoparticle internalization into cells via non-specific pathways. The nanoparticles were comprised of commercial quantum dots (QDs) that were highly visible under a fluorescence confocal microscope.

Angewandte Chemie, EarlyView.Stable aggregates of a new hydrogen‐bond mediated porphyrin‐perylenebisimide (PBI) bola‐type supra‐amphiphile have been synthesized by lyophilization of solutions of both single molecules in THF/water mixtures, followed by redispersion in pure water. Cryogenic transmission electron microscopy verifies the spherical morphology.
