Abstract

The present invention belongs to the field of hybridized organic-inorganic material technology, and is especially the assembling method of Fullerene derivative in meso porous material SBA-15. by means of chemical bonding, the [60] Fullerene derivative C60(CHCOOH)2 is introduced into the network of meso porous silicon material SBA-15. C60(CHCOOH)2 molecules are single layer distributed in SBA-15 channel to control the pore size of the meso porous material effectively, so that the material may be applied in matter separation. In the same time, the material has the fluorescent characteristic of Fullerene derivative maintained, that is, the material has red shift with the increasing exciting wavelength and thus shows application foreground in optical devices.

Description

technical field [0001] The invention belongs to the technical field of inorganic-organic hybrid materials, and in particular relates to an assembly method of fullerene derivatives in silicon-based mesoporous material SBA-15. Background technique [0002] since C 60 Since its discovery, it has attracted a large number of scientific researchers to conduct extensive research on fullerene and its derivatives in terms of light, electricity, magnetism, physiology and even medical applications. Recently, research on microreactors at the molecular level has become a hot topic, such as unimolecular chemistry occurring in nanostructures has become a topic of great interest to chemists. This is because by studying the environment that has strict control over the reaction molecules to control the chemical reaction, a lot of information can be obtained using the local environment, and materials with new functional properties can be obtained. So far, fullerenes have always been introduc...
