Toward the creation of stable, functionalized metal clusters.

Rational design, characterization and catalytic application of metal clusters functionalized with hydrophilic, chiral ligands: a proof of principle study.

A proof of principle is presented for the rational design of metal clusters functionalized with hydrophilic, chiral ligands. A colloidal method is used to prepare "unprotected" metal clusters of well-defined size that are subsequently functionalized in a separate step with hydrophilic, chiral ligands. As clusters from the same batch are functionalized with different organic molecules while the ...

Alkynyl-functionalized gold NHC complexes and their coinage metal clusters.

Phenylpropynyl-functionalized imidazolium salts, as well as their gold complexes, were prepared in excellent yields affording suitable starting materials for metal cluster synthesis. The reactions of these gold complexes with coinage metal phenylacetylides [M(CCPh)](x) (M = Cu, Ag) resulted in the formation of novel heterometallic hexanuclear clusters which exhibit mixed metallophillic interact...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...

Designed synthesis of multi-functional carboranes and organotransition metal—carborane complexes

General synthetic routes to functionalized Cand B-substituted derivatives of nido-C9B4H8, C4B5H12, and C2B3H72 are described together with their use as buiTding-blociZ units in the planned construction of multidecker transition-metal sandwich complexes and related systems. Specifically discussed are (1) synthesis of C2B4 nido-carboranes containing sterically demanding and/or electronically acti...

Efficient removal of cobalt(II) ion from aqueous solution using amide-functionalized metal-organic framework

In this study, an amide-functionalized metal-organic framework, namely TMU-24 was selected to adsorb Co(II) from wastewater with an adsorption capacity of 500 mg. g-1 in less than 20 minutes in neutral pH (pH=7). The effect of diverse parameters such as adsorbent dosage, competitive ions, and contact time on the adsorption process was investigated to find the optimal amounts of them. Also, the ...
