Synthesis and properties of supramolecular systems based on silica

“…Undoubtedly the immobilization of β-cyclodextrin on a surface of insoluble supports (silica, alumina, aluminosilicates) [10,[12][13][14][15][16][17][18][19][20] offers advantages relative to cyclodextrins attached to polymers. The most important one is that related to the fast kinetics of the process in the former relative to the latter due to the absence of internal diffusion and swelling of the material.…”
