Multidimensional structures made by gold nanoparticles with shape-adaptive grafting layers

Abstract

The ability of gold nanoparticles grafted with soft, adaptive organic layers made of two types of thiol molecules, n-alkyl and mesogenic ones, to form spontaneously long-range positionally ordered structures is shown. It was found that molecular structure of mesogenic thiols as well as the n-alkyl thiols can affect the type of the phase. A number of structures, smectic, undulated smectic and columnar phases, were obtained thanks to the self-segregation of mesogenic and simple n-alkyl ligands at the nanoparticle surface.
