Click Chemistry in Mesoporous Materials: Functionalization of Porous Silicon Rugate Filters

In this paper we report the use of the optical properties of porous silicon photonic crystals, combined with the chemical versatility of acetylene-terminated SAMs, to demonstrate the applicability of “click” chemistry to mesoporous materials. Cu(I)-catalyzed alkyne−azide cycloaddition reactions were employed to modify the internal pore surfaces through a two-step hydrosilylation/cycloaddition procedure. A positive outcome of this catalytic...
