    摘要: The present invention provides a hexagonal mesoporous silica comprising a photo-dimerizable organic functional group provided at the entrances of the pores thereof, and a hexagonal mesoporous silica comprising a functional substance filled in the pores thereof and a dimerized organic functional group provided at the entrances of the pores to close the entrances. These hexagonal mesoporous silicas allow a substance incorporated therein to be controllably released. The present invention also provides a method of producing the mesoporous silica, and a method using the mesoporous silica to control the release of a functional substance incorporated therein.

    摘要: Hybrid silica polymer applicable to electrochemical elements and a method for economical production thereof, the former excelling in thermal stability, mechanical stability, solvent resistance, and proton conductivity at low humidity is provided. The method includes a step of heating a mixture of 3-mercaptopropyltrialkoxylsilane, surfactant, water, and base or acid for their reaction with one another at 25 to 180° C., thereby providing a hybrid thiol group-containing silica polymer, and an optional step of oxidizing said hybrid thiol group-containing silica polymer with a peroxide, thereby giving a hybrid silica polymer which is composed of hybrid (thiol group-containing and/or sulfonic group-containing) silica polymer. The resulting silica polymer is used as a proton conducting material for electrochemical elements such as fuel cells, capacitors, and electrolytic cells.
