Description
Summary:[Display omitted] A siloles products are readily synthesized with anhydrous and low temperature, and the compounds are purified by column chromatography of neutral alumina with yields of more than 85 %. Their structural characteristics were analyzed by X-ray crystal structure. Siloles are a good δ*-π* conjugate system with low LUMO value. They have a higher emission of blue fluorescence under UV light. Luminescence sensing experiments exhibit that four siloles products can detect TNP with high sensitivity and selectivity. The detection mechanism of four siloles products towards TNP have been discussed.
