The alkylammonium-exchanged swellable layered clay minerals have been prepared and used as immobilizing media for photoactive organic compounds. Anthracene, pyrene and p-aminoazobenzene were incorporated into the interlayer spaces of the long-chain alkylammonium exchanged-smectites. It was revealed from the photoprocesses of the intercalated species that the adsorptive properties of the host materials varied depending on the arrangements of the interlayer alkylammoniumions. Besides the hydrophobic modification by long chain alkylammonium ions. 2-dimensional microporous structure was obtained by pillaring with tetramethylammonium ion.
