Patterning of polyoxometalate rings on gold nanorods

We report a facile method for the self-assembly of various polyoxometalates (POMs) on cetyltriethylammonium bromide-covered gold nanorods (GNRs) into an ordered array of POM rings along their long axis. The periodic distance of POM rings can be tuned by the POM charge and the transverse curvature of...

Description
Summary:We report a facile method for the self-assembly of various polyoxometalates (POMs) on cetyltriethylammonium bromide-covered gold nanorods (GNRs) into an ordered array of POM rings along their long axis. The periodic distance of POM rings can be tuned by the POM charge and the transverse curvature of GNRs. Polyoxometalates (POMs) were self-assembled on cetyltriethylammonium bromide-covered gold nanorods and formed periodic POM rings, which could be used as templates for the synthesis of Ag nano-rings.
