Chiral Copper(0) Nanoparticles: Direct Synthesis and Interfacial Chiral Induction via Phase Transfer of Copper Nanoparticles

Autor: Yu Imanaka, Tsukasa Nakahodo, Hisashi Fujihara

Publikováno v: ChemistrySelect. 2:5806-5809

No clear-cut example has been hitherto known for the phase transfer involving the ligand exchange of copper nanoparticles (NPs) from an aqueous phase into an organic phase, and chiral copper NPs. We present the first isolation of chiral copper(0) NPs

Optically Active Linear and Hyperbranched Polythiophenes Bearing BINOL Derivatives Emitting Circularly Polarized Luminescence

Autor: Michiya Fujiki, Atsushi Sudo, Takumi Kitatobe, Nobuo Tajima, Hisashi Fujihara, Motohiro Shizuma, Nobuyuki Hara, Yoshitane Imai, Mamoru Okazaki

Publikováno v: Chemistry Letters. 47:1200-1202

Luminophores are key components in several optoelectronic applications and the development of methods for the synthesis of novel highly efficient luminophores is an important objective. Herein, new linear and hyperbranched polythiophenes bearing BINO

Remarkably StableS-Oxides of Calix[4]thiophenes and Their Sulfonium Ylide from Reaction ofS-Oxide with Acetylene Derivative

Autor: Tsukasa Nakahodo, Hisashi Fujihara, Noritaka Takeuchi

Publikováno v: Chemistry Letters. 46:389-391

The oxidation of macrocyclic thiophenes, such as the calix[4]thiophenes, with m-chloroperbenzoic acid in the presence of BF3·OEt2 afforded the remarkably stable mono- and bis-S-oxides based on their X-ray crystal structures. The stable mono-S-oxide

Publikováno v: Dalton transactions (Cambridge, England : 2003). 45(11)

A chiral phosphine cavitand 1 induced the formation of chiral metal (Ru, Rh, Pd, Ag, Pt, and Au) nanoparticles (NPs). The ligand 1 of the chiral metal NPs prevents both thermal racemization and ligand exchange with a thiol, but the organic molecules
