| Research Abstract |
This research focuses on the syntheses of ordered porous silica based on alkoxy-modification of a cubic siloxane unit (Si_8O_12; D4R). 1) and their solid-state hydrolysis. The following results have been obtained: 1) a new D4R compound that is modified with seven methoxy groups and one adamantoxy group was synthesized. The molecular crystal of this compound was treated with acidic water and subsequently calcined, giving highly porous silica. 2) a new type of organo-silica molecular crystal with high thermal stability was obtained by modifying D4R with eight adamantoxy groups, although it was found to be non-porous. 3) porous silica was obtained by cross-linking of H_8Si_8O_12 with propanediols, followed by hydrolysis to remove organics. These results provide a new pathway to nanoporous materials with controlled architectures.
