Abstract

An azobenzene-derived surfactant behaves as a "smart" molecule. Not only is it used as the structure-directing agent to synthesize unique mesoporous silica nanospheres, but it can also be quickly released from the silica framework with UV light and subsequently recycled.

Keywords: mesoporous materials; photoresponse; self-assembly,azobenzene; silica nanospheres.
