Monolayer-protected cluster molecules.
In this report, we evaluate the present state of the rapidly emerging field of monolayer-protected cluster (MPC) molecules with regard to their synthesis and monolayer functionalization, their core and monolayer structure, their composition, and their properties. Finally, we canvass some of the important remaining research opportunities involving MPCs.
متن کاملMelting of monolayer protected cluster superlattices
Melting of crystalline solids ~superlattices! of octadecanethiol and octanethiol protected silver clusters has been studied with x-ray powder diffraction ~XRD!, differential scanning calorimetry ~DSC!, and infrared ~IR! spectroscopy. These solids have been compared with the silver thiolate layered compounds in view of their similarity in alkyl chain packing and x-ray diffraction patterns. Super...

متن کاملArenethiolate Monolayer-Protected Gold Clusters
Nanometer-sized gold clusters stabilized by monolayers of arenethiolates prepared using the Brust reaction are somewhat larger (by TEM) and less thermally stable (by TGA) than those prepared under similar conditions and stabilized by alkanethiolates. Like the latter, the mean core size decreases for synthetic conditions based on larger thiol/Au ratios. The differential pulse voltammetry of the ...
متن کاملDistance-dependent electron hopping conductivity and nanoscale lithography of chemically-linked gold monolayer protected cluster films
Films of monolayer protected Au clusters (MPCs) with mixed alkanethiolate and -carboxylate alkanethiolate monolayers, linked together by carboxylate–Cu2+–carboxylate bridges, exhibit average edge-to-edge cluster spacings that vary with the numbers of methylene segments in the alkanethiolate ligand as determined by a combined atomic force microscopy (AFM)/UV-Vis spectroscopy method. The electron...
