Mesoporous silica having controlled-release on-off control function, production method thereof and method using same

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.
