Electrospray soft-landing for the construction of non-covalent molecular nanostructures using charged droplets under ambient conditions†
Abstract
An electrospray soft-landing (SL) technique was utilized to create 2D nano-networks on HOPG under ambient conditions. A 2,3,6,7,10,11-hexahydroxy-triphenylene close-packing structure was observed by STM instead of unorganized clusters, as well as amine and acid nanostructures. On C18H37NH2 networks, C18H37NH3+ was identified by XPS analysis revealing retaining of charges on the SL-modified surface.
