Effects of chain length on the size, stability, and electronic structure of redox-active organic- inorganic hybrid polyoxometalate micelles

摘要

Double-chain redox-active surfactants based on hybrid poly- oxometalates show solvent-dependent assembly into nanoscale micellar architectures. These organic-inorganic hybrid amphi- philes, of the general formula K6ijP2W17O61ijPOC6H4OijCnH2n+1))2], were prepared with varying aliphatic chain lengths (n = 10, 12, 14, 16, 18 and 20) and display different multi-electron redox behav- iours in their molecular and supramolecular forms. Furthermore, modification of the length of the hydrophobic tail is an effective strategy for controlling the stability and electronic properties of the supramolecular nanostructures.
