Periodic mesoporous phenylenesilicas with ether or sulfide hinge groups - a new class of PMOs with ligand channels

A new class of periodic mesoporous organosilicas (PMOs) with 4-phenyl ether and 4-phenyl sulfide bridge-bonded silsesquioxanes integrated into the pore walls to create ligand channels have been synthesized using inorganic salt-assisted self-assembly directed by a supramolecular polyoxyethylene (10) stearyl ether (Brij 76) template.
