Abstract

The analysis of the structure and hydration of organic-inorganic composites based on MCM-41
according to the infrared diffuse reflectance spectroscopy including in situ heating is presented. The
results have allowed to differentiate the free silanol groups, as well as participating in the formation of
hydrogen bonds. IR spectra of materials shows the similar chemical nature, the structure and hydration of
the highly ordered MCM-41 and its composites with molecular imprinted flavonoid. On the basis of
infrared diffuse reflectance spectroscopy it was shown changes and hydration structure of mesoporous
silicate MCM-41, as well as materials modified with N-trimethoxysilylpropyl-N, N, Ntrimethylammonium
chloride (TMTMAS), dichlorometylphenylsilane (DCMPS) and
dimetoxydimetylsilane (DMODMS).
