“…Higher monomer/excimer intensity ratio for the 2C 18 2C 1 N + -montmorillonite system than that for the C 18 3C 1 N + -system suggests that the adsorbed pyrene molecules are more isolated in the interlayer space of the 2C 18 2C 1 N + -montmorillonite. Similar tendency was observed when other smectite clays were used [13].…”

“…The intercalated alkylammonium ions arrange as mono-, bi-, pseudo-tri-molecular layers with their alkyl chains parallel to the silicate layers, in addition to the paraffin-type arrangements as schematically shown in Fig. 6.1 [7,13]. The structures varied depending on the size of the intercalated ions ( Fig.…”

“…The organophilic smectites have been investigated as supports of guest species (both cationic and nonionic), and the states of the guest species are affected by the nanostructures of the organophilic smectites [7,13,[36][37][38][39][40][41][42][43][44][45][46]. Pyrene is a useful photoluminescence molecule to provide the information on the interlayer nanostructure by the formation of excited state dimer (excimer) even at low concentration.…”

Intercalation of guest species into layered materials is a way of constructing two-dimensionally ordered inorganic-organic molecular or supramolecular or hybrid assembly with unique microstructures controlled by host-guest and guestguest interactions [1][2][3][4][5][6][7][8][9]. One of the most unique characteristics of intercalation chemistry is the expansion of the interlayer space upon intercalation of guest species. The expanded interlayer space by the intercalation can be used to immobilize guest species further, since the space was geometrically and chemically modified to accommodate wider variety of guest species. This 'expandable' 2-dimensional nano-space is useful as a nano-vessel or nano-reaction environment for immobilizing various kinds of molecular functional species.The properties of intercalation compounds are largely affected by the population (or density or distance between adjacent species) of functional units and some useful functions are emerged only when appropriate population (nanostructure) is achieved. The interactions between host and guest have been investigated based on the structural consideration of resulting intercalation compounds (or interlayer microstructures). The characterization includes X-ray and electron diffraction and composition, chemical bonding between host and guest using vibrational spectroscopy, electronic states of the confined guests by electronic spectroscopy, strength of interactions using thermal analyses (desorption and decomposition), and more directly using advanced microscopies.

“…Intercalation is a well-known word, but in this work it means the insertion of different types of neutral polar organic molecules and organic cations into the interlayer spaces of clay minerals. Intercalation of layered silicates creates new perspective materials such as sorbents, catalysts [1,2], nanocomposites [3][4][5][6][7], and materials with interesting optical properties for optoelectronic devices [8][9][10][11][12][13].…”

“…Intercalation of organic dyes into layered silicates is one method of producing ordered organic-inorganic hybrid materials with interesting photofunctions [1][2][3][4][5][6][7][8][9][10][11]. Especially, the smectite group is used as a very convenient host structure for the intercalation of organic dyes for two reasons.…”
