Nano-sized periodic mesoporous organocilica(PMO) materials were synthesized using triblockcopolymer P123 and F127 as template and aromatic organic moieties-bridged organosilane 1,4-bis(triethoxysilyl)benzene and 4,4-bis(triethoxysilyl)biphenyl as organosilica precursor via self-assembly process. The PMO materials synthesized by using 1,4-bis(triethoxysilyl)benzene as organosilica precursor showed that nano-sized particles with nanopore are produced. In addition, we synthesized PMOs under various conditions, such as temperature(50~100℃), reaction condition (static/stirring), for observing this phenomenon. These materials have been characterized by N2 sorption method, transmission electron microscopy(TEM) and small angle X-ray scattering(SAXS), IR, and SEM. These PMO materials have a potential application in the area of separation, catalysis, and sensor, etc. |
