摘要：
A set of permethylated 6I-(ω-alkenoyl)-6I-amino-6I-deoxy-β-cyclodextrin derivatives with different chain length of the alkenoyl group (used as a spacer) was synthesized. These derivatives were attached by photochemically activated hydrosilylation reaction to the surface of porous silicon. Photoluminescence response of the modified PS to controlled concentrations of various molecules in gas phase revealed strong host-guest interactions between β-cyclodextrin and the detected molecules. The strongest interaction was observed for aromatic molecules, which have the optimal size to fit into the β-cyclodextrin molecular cavity.
