New Hybrid Organic‐inorganic Multifunctional Materials Based on Polydopamine‐like Chemistry

A simple one-pot procedure under mild conditions has been developed with the aim of preparing a set hybrid organic-inorganic multifunctional materials. This is based on use catechol and KIO4 as oxidizing agent in conjunction 3-aminopropyl-, substituted 3-aminopropyl- 3-methylimidazolium-1-trimethoxypropylsilane mimicking polydopamine-like chemistry. Reactions were carried out water at room temperature 70 °C to give fifteen materials that characterised by using several techniques (nitrogen physisorption, TGA, XPS, 13C 29Si CP-MAS NMR, IR, pHPZC). Knoevenagel reaction was chosen good probe investigate availability functional groups surface The most active catalytic tested recycling procedures. Such broad interest for scientific community it open doors development new purposes.
