چکیده

Gold nanoparticles with average diameter of 1.0 nm and narrow size distribution can be easily obtained by disproportionation of Au(+) ions, in the presence of a persulfurated coronene dendrimer that favors encounters between Au(+) ions and protects the resulting small nanoparticles from further aggregation.

Structural analysis of PdAu dendrimer-encapsulated bimetallic nanoparticles.

PdAu dendrimer-encapsulated nanoparticles (DENs) were prepared via sequential reduction of the component metals. When Au is reduced onto 55-atom, preformed Pd DEN cores, analysis by UV-vis spectroscopy, electron microscopy, and extended X-ray absorption fine structure (EXAFS) spectroscopy leads to a model consistent with inversion of the two metals. That is, Au migrates into the core and Pd res...

Versatile routes for synthesis of diarylamines through acceptorless dehydrogenative aromatization catalysis over supported gold-palladium bimetallic nanoparticles.

Diarylamines are an important class of widely utilized chemicals, and development of diverse procedures for their synthesis is of great importance. Herein, we have successfully developed novel versatile catalytic procedures for the synthesis of diarylamines through acceptorless dehydrogenative aromatization. In the presence of a gold-palladium alloy nanoparticle catalyst (Au-Pd/TiO2), various s...

Electrochemical synthesis and electrocatalytic properties of Au@Pt dendrimer-encapsulated nanoparticles.

Dendrimer-encapsulated Au nanoparticles comprised of an average of 147 atoms were synthesized and immobilized on a glassy carbon electrode. A one-atom-thick shell of Cu was added to the Au core by electrochemical underpotential deposition, and then this shell was replaced with Pt by galvanic exchange. The results indicate that this synthetic approach leads to well-defined core/shell nanoparticl...

Synthesis of PEGylated low generation dendrimer-entrapped gold nanoparticles for CT imaging applications.

Dendrimer-entrapped gold nanoparticles (Au DENPs) can be formed using low-generation dendrimers pre-modified by polyethylene glycol (PEG). The formed PEGylated Au DENPs with desirable stability, cytocompatibility, and X-ray attenuation properties enable efficient computed tomography imaging of the heart and tumor model of mice.

Persulfurated Coronene: A New Generation of "Sulflower".

We report the first synthesis of a persulfurated polycyclic aromatic hydrocarbon (PAH) as a next-generation "sulflower." In this novel PAH, disulfide units establish an all-sulfur periphery around a coronene core. The structure, electronic properties, and redox behavior were investigated by microscopic, spectroscopic and electrochemical methods and supported by density functional theory. The su...
