Zigzag Boron−Carbon Nanotubes with Quasi-planar Tetracoordinate Carbons
Four kinds of novel zigzag boron−carbon nanotubes with quasi-planar tetracoordinate carbons (2m, 0, i) (m = 3−6; i = 1−4) have been constructed, and their structures,... -
Femtosecond Dynamics of Isolated Phenylcarbenes
International audience; Understanding the primary photophysical processes in molecules is essential for interpreting their photochemistry, because molecules rarely react from... -
Pyridinium 1,1′-Binaphthyl-2,2′-disulfonates as Highly Effective Chiral Brøns...
We have established, for the first time, a practical synthesis of chiral 1,1′-binaphthyl-2,2′-disulfonic acid (BINSA 1) from inexpensive BINOL. An efficient enantioselective... -
Iridium-Catalyzed Asymmetric Hydrogenation of Cyclic Enamines
The first highly enantioselective iridium-catalyzed hydrogenation of cyclic enamines has been developed. This new reaction provided an efficient method for the synthesis of... -
Liesegang Rings Engineered from Charged Nanoparticles
Functionalized nanoparticles (NPs) serve as building blocks of self-organizing chemical patterns comprising periodic zones of nanoparticle precipitation. In contrast to ions,... -
Triggering DNAzymes with Light: A Photoactive C8 Thioether-Linked Adenosine
Herein we report evidence for a light-inducible DNAzyme. In so doing, we also disclose the synthesis and photochemical properties of a novel nucleoside:... -
Macromolecular Helicity Induction in a Cationic Polyacetylene Assisted by an ...
We report the first example of the replication of macromolecular helicity. An optically active helical and anionic polyelectrolyte, the sodium salt of poly(4-carboxyphenyl... -
