| Outline of Final Research Achievements |
In this study, novel nanoporous siloxane-based molecules were produced. A 12-membered cyclic siloxane possessing alkoxysilyl groups was synthesized from organometallasiloxane containing a 12-membered ring with Si-Me and Si-O- groups. The cyclic structure was retained in the hydrolysis and condensation reactions. The membrane composed of the cyclic siloxanes showed a molecular sieving effect. Furthermore, cyclohexasiloxanes with long alkyl chains and triethoxysilyl groups were synthesized, and lamellar mesostructured siloxane-based materials were obtained by self-assembly of these cyclosiloxane compounds. On the other hand, a regioselectively functionalized cubic siloxane where two adjacent corners were modified with Si-O-C bonds was synthesized and novel cage-like siloxane-based macrocycles that resemble the aperture of zeolites were successfully formed by hydrolysis and condensation.
