摘要：

(Figure Presented) Kicking out cholesterol: The release of guest molecules (cholesterol) included in the pores of mesoporous silica is promoted by simultaneous irradiation with UV and visible light. The reversible cis-trans photoisomerization of azobenzene substituents on the pore surface causes a stirring action, which accelerates the diffusion of the guest from the pores (see picture), thus providing an intelligent controlled-release method. © 2007 Wiley-VCH Verlag GmbH & Co.
