Synthesis of large-pore periodic mesoporous organosilica (PMO) with bicontinuous cubic structure of Ia-3d symmetry

Ordered three-dimensional (3-D) bicontinuous cubic la-3d-type periodic mesoporous organosilica (PMO) with large pore size ( > 6 nm) has been synthesized by using triblock copolymer P123 as a template and 1,2-bis(triethoxysilyl)ethane as an organically bridged silica source.
