Clickable Mesoporous Silica via Functionalization with 1,ω-Alkenes

Abstract

Tuning the surface properties of mesoporous silica is desirable for many applications, such as catalysis. We present a new modification method of calcined mesoporous silica, based on the thermal grafting of 1,7-octadiene. This easy method generates a high loading of terminal alkenes. We show that the modified surface is directly available for thiol-ene click chemistry, which enables a wide variety of molecules to be attached to this alkene-functionalized mesoporous silica.
