Preliminary exchange with Cu2+ reveals differences in ordering in the two types of oxide-pillared materials, ascribed to differences in precursor insertion during their preparation. In both oxide-pillared types, the pyr rapidly polymerises in the pores (not on the surface). Optical spectra and XPS evidence point to the presence of more than one type of pyr polymer, and hence of a porous system. The optical properties are typical of mixed neutral and bipolaron states with the presence of low-oxidation level polypyrrole. Based on similarities in optical properties with zeolite analogues, it is suggested that the starting materials contain porous systems similar to both zeolite-Y and mordenite present together. As for zeolite-Y and mordenite analogues, the materials have negligible conductances ( < 10−9 Ω−1 cm−1), which is ascribed to the presence of only short polymeric pyr units.
