Abstract
The mobility of molecular species in the two dimensional nanospace, organically modified layered silicates, was controlled by the small difference in the molecular structure of the modifiers, dioleyldimethylammonium and dioctadecyldimethylammonium ions. Dioleyldimethylammonium-bentonite was used as host to accommodate guests and the results were compared with those for dioctadecyldimethylammonium-bentonite, which is a well-known organophilic bentonite. The dioleyldimethylammonium-bentonite exhibited superior swelling behavior in tetrahydrofuran, benzene, toluene, and xylene. The intercalation of pyrene by solid-solid reactions was achieved within shorter time for the dioleyldimethylammonium-bentonite than that for the dioctadecyldimethylammonium-bentonite. The intercalated pyrene in the interlayer space of the dioleyldimethylammonium-bentonite has higher mobility as shown by the excimer formation in the photoluminescence spectra. These observations indicated the useful characteristics of the dioleyldimethylammonium-bentonite over well-known dioctadecyldimethylammonium-bentonite for the applications.
