## Abstract The first synthesis of a chiral periodic mesoporous organosilica (PMO) carrying benzylic ether bridging groups is reported. By hydrolysis and condensation of the new designed chiral organosilica precursor 1,4βbis(triethoxysilyl)β2β(1βmethoxyethyl)benzene (BTEMEB) in the presence of the
## Abstract In this study we report the synthesis of a new class of materials called hybrid periodic mesoporous organosilicas (HPMOs). ByΒ coupling a silsesquioxane precursor through at least two chemical linkages to the mesopore walls of a preβexisting periodic mesoporous silica (PMS) or periodic m
