Conductive polymers (polyaniline) and semiconductor clusters
(PbI2) have been synthesized in three- and one-dimensional
channels of zeolites FAU, MCM-41 and LTL. Considerations on stoichiometry,
IR spectra and absence of bulk conductivity of the aniline/zeolite
samples lead to the conclusion that polymer is formed inside the host
channel system. The polyaniline/zeolite and PbI2/LTL zeolite
represent a specific class of materials containing, respectively,
conducting or semiconducting species encapsulated in crystalline inorganic
hosts with channels of molecular dimensions.
