Covalent Immobilization of a TiW5 Polyoxometalate on Derivatized Silicon Surfaces

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 func...

Description
Summary:	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.
