Layer-type cyclodextrin complexes

It was pointed ouF that while ionomer-modified electrodes have greater selectivity than naked electrodes, ionomers provide only a general form of selectivity (charge type and mass or hydrophobicity selectivity), and special methods were suggested to improve specific selectivity. For example, it was thought that applying an additional cellulose acetate layer over the Nafion film would make the electrode selective with respect to dopamine specifically (in contrast to other neurotransmitters). To make the electrode system specifically selective to o-nitrophenol (in contrast to /(-isomer), a complexation with cyclodextrin was performed, which increased the selectivity ratio one order of magnitude with respect to the o-isomer. ... [Pg.101]

Host inolecules may be broadly classified into two main types those that form molecular complexes by fitting convex guests into the concave cavity of the host (examples include cyclodextrins, cyclophanes. calixar-enes, cycloveratrylenes, and various carcerands ) and those that form lattice inclusion compounds by packing in such a manner as to leave cavities, channels, or layers in the crystal structure so as to accommodate various guest... [Pg.696]

Various classes of compounds, including montmorillonite and cyclodextrin, are known to serve as host compounds having several types of inclusion spaces, such as three-dimensional cages, single or parallel channels and layers [3]. In spite of the variety of host compounds, little attention has been paid to the possible complexation of two or more host components of different kinds all inclusion... [Pg.807]
