High yield, large scale synthesis of thiolate-protected Ag7 clusters.
نویسندگان
چکیده
We report a high yielding synthesis of truly monodisperse, thiolate-protected silver clusters via a rationally designed approach. The cluster composition was determined by electrospray ionization (ESI) mass spectrometry to be Ag(7)(DMSA)(4), where DMSA represents meso-2,3-dimercaptosuccinic acid. The Ag(7) thiolate clusters exhibit distinct optical properties. The approach developed in this work provides some insight into the cluster growth kinetics and may be extendable to the synthesis of other sized silver nanoclusters.

Separation of precise compositions of noble metal clusters protected with mixed ligands.
This report describes the precise and systematic synthesis of PdAu24 clusters protected with two types of thiolate ligands (-SR1 and -SR2). It involved high-resolution separation of metal clusters containing a distribution of chemical compositions, PdAu24(SR1)18-n(SR2)n (n = 0, 1, 2, ..., 18), to individual clusters of specific n using high-performance liquid chromatography. Similar high-resolu...
متن کاملUnraveling a generic growth pattern in structure evolution of thiolate-protected gold nanoclusters.
Precise control of the growth of thiolate-protected gold nanoclusters is a prerequisite for their applications in catalysis and bioengineering. Here, we bring to bear a new series of thiolate-protected nanoclusters with a unique growth pattern, i.e., Au20(SR)16, Au28(SR)20, Au36(SR)24, Au44(SR)28, and Au52(SR)32. These nanoclusters can be viewed as resulting from the stepwise addition of a comm...
متن کاملInvestigating the structural evolution of thiolate protected gold clusters from first-principles.
Unlike bulk materials, the physicochemical properties of nano-sized metal clusters can be strongly dependent on their atomic structure and size. Over the past two decades, major progress has been made in both the synthesis and characterization of a special class of ligated metal nanoclusters, namely, the thiolate-protected gold clusters with size less than 2 nm. Nevertheless, the determination ...
متن کاملFacile and rapid synthesis of a dithiol-protected Ag7 quantum cluster for selective adsorption of cationic dyes.
We report a facile and rapid (less than 15 min) synthesis of atomically precise, dithiol-protected, silver quantum cluster, Ag7(DMSA)4 (DMSA: meso-2,3-dimercaptosuccinic acid), through a modified solid state route. The as-synthesized cluster exhibits molecular optical absorption features with a prominent λmax at ~500 nm. Composition of the cluster was confirmed using various spectroscopic and m...
متن کاملThiolate-protected Ni39 and Ni41 nanoclusters: synthesis, self-assembly and magnetic properties.
Thiolate-protected soluble nickel clusters, Ni(39)(SC(2)H(4)Ph)24 and Ni(41)(SC(2)H(4)Ph)25, were synthesized via a wet chemical method. The cluster formulae were identified by MALDI-TOF. Possible structures of the clusters were discussed. These clusters exhibit ferromagnetism with hysteresis loops in the 1.8-300 K range. By solvent evaporation, the clusters can self-assemble into simple cubic ...
