| Outline of Final Research Achievements |
Molecular-Net Sieving where silica network space separates molecules based on the molecular-sieving mechanism was proposed to develop highly permselective membranes. For this purpose, new silicon alkoxides with POSS structures were developed, and the pore structures were evaluated by ellipsometric porosimetry and positron annihilation. Furthermore, pore sizes of silica-based membranes were successfully controlled by optimizing sol preparation condition, and the size of the liking units of bridged alkoxy silanes. In addition, pH swing method was effective to increase permeances.
