Novel crystalline organic-inorganic hybrid silicate material composed of the alternate stacking of semi-layered zeolite and microporous organic layers.

A novel type of crystalline organic-inorganic hybrid microporous silicate material, KCS-5, was synthesized supposedly from a lamellar precursor composed of amphiphilic organosilicic acids. This well-ordered material has a crystalline structure, is thermally stable up to 500 °C and has lipophilic 1-dimensional micropores.
