A Self-template Method for Mesoporous Organosilica Particles

Mesoporous organosilica particles with large internal pores were prepared by a self-template, self-assembly process using homo- and heterocondensation of silane mixture, and extraction of highly soluble, homocondensed PTMS. This method not only provides a simple synthetic route without using an expensive template but also endows chemical flexibility to mesoporous particles owing to alkyl and aryl functional groups in organosilanes.
