Janus bifunctional periodic mesoporous organosilica

A novel protocol for the synthesis of a Janus periodic mesoporous organosilica material (JPMO) is presented here. In this strategy, the surface of the hollow silica material was selectively functionalized with two different bridged organic-inorganic hybrid groups. It was found that the resulting bifunctional material is able to form a stable Pickering emulsion. This new type of PMO material may serve for widespread applications in various fields related to material science and catalysis.
