Highly ordered hexagonal mesoporous organosilicas with large pore size > 4 nm) were synthesized by non-aqueous solvent evaporation method using triblock copolymers as the structure-directing a-gents and 1,2-bis(triethoxysilyl)ethane as the organically bridged silica source. The mesoprous organosilicas were characterized by small-angle powder X ray diffraction(XRD), transmission electron microscopy (TEM), nitrogen adsorption, 29Si MAS NMR spectroscopy and scanning electron microscope(SEM).
