We synthesized the nanoporous organic-inorganic frameworks by heat treatment of solution mixture comprised of urea network (UN) as template and bis(triethoxysiliyl)ethane (BTESE) as organosilica precursor in dimethylformamide (DMF) solvent. The solvent evaporation induced UN gelation in phase separating mixture of UN sol and inorganic precursors produces reticulated nanoporous organic-inorganic frameworks with the highly open and randomly connected pores that are adjusted by varying the compositions and species of inorganic components. The resultant films show unique hybrid structure consisting of organic skeleton and inorganic crust that brings considerable advantages for their application of selective molecular transport. Also, the nanoporous hybrid films can be easily transformed to the porous silica by organics calcination. This work was supported by grants from Korea CCS R&D Center, funded by the Ministry of Education, Science and Technology of Korean. [20120008889]
