ResumoThe giant, nanoporous Keplerate (NH4)42[Mo132O372(CH3COO)30(H2O)72] was incorporated into a permeable ultrathin film using a stepwise self-assembly strategy. Alternating adsorption of the Keplerate anions and PAH results in single layers with an apparent surface coverage of ≈50%. Such permeable composite coatings may lead into a practical approach to utilize nanoporous polyoxometalate clusters in sensors or heterogeneous catalysts.
