Template synthesis of polypyrrole (PPy) in three-dimensional interconnected channels was attained using vapor phase polymerization by the oxidation of preadsorbed pyrrole within a microporous metalorganic framework of ICu3(btc)(2)](n), (btc = benzene-1,3,5-tricarboxylate) upon exposure to FeCl3 vapor. The formation of Cl-doped PPy was confirmed by material characterizations. Moreover, the product exhibited interesting microstructure features with an octahedronlike shape and high porosity, possibly a result of the Cu-3(btc)(2) template. The BET surface area of the porous PPy was 455 m(2)/g and its pore size was distributed in the range of 1-10 nm. In preliminary measurements of cyclic voltammetry, the micro/mesoporous PPy-modified electrode exhibited a higher quasireversible electrochemical response for ferricyanide than a bare glass carbon electrode.
