Abstract

Covalent ties: The polyoxometalate (nBu4N)3[(MeO) TiW5O18] is easily anchored to alkanol-functionalized surfaces of porous and single-crystal silicon (see picture, polyhedra: polyoxometalate, dark blue: Si surface). Scanning tunneling microscopy reveals the growth of 35-50 nm diameter islands on functionalized Si(111), which suggests that the immobilized polyoxometalates act as nucleation sites for electrostatic aggregation. © 2005 Wiley-VCH Verlag GmbH & Co.
