0D to 1D Switching of Hybrid Polyoxometalate Assemblies at the Nanoscale by Using Molecular Control.

Watered down: Polyoxometalate (POM) hybrids based on [C16 H36 N]4 [SiW11 O40 (SiCH2 CH2 CH2 NH2 ⋅HCl)2 ] covalently functionalized with different lengths of alkyl chains (n=0, 5, or 10) terminated with azobenzene moieties have been successfully prepared. The assembly behavior of these POMs can be affected by hydrophobic and π-π interactions by finely tuning the lengths of the alkyl chains in different ratios of CH3 CN/H2 O.
