Ultrathin Composite Films Incorporating the Nanoporous Isopolyoxomolybdate ``Keplerate'' (NH4)(42)Mo132O372- (CH3COO)(30)(H2O)(72) The 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 approximate to 50\%. Such permeable composite coatings may lead into a practical approach to utilize nanoporous polyoxometalate clusters in sensors or heterogeneous catalysts.
