| Research Abstract |
Following the research proposal, these significant results described below were accomplished. First in the establishment of basic methods for the syntheses of functional materials: (1) Cyclic silanols those serve as the versatile starting compounds for various siloxane materials were easily accessed in high yields, (2) Investigation of substituents made it possible to afford the products with single stereo structure. For innovational core compounds synthesis with reactive groups, (1) cage octasilsesquioxanes with eight reactive substituents (octopus), (2) laddersiloxanes with two reactive groups on the both ends were synthesized. In addition, cage hexasilsesquioxanes with two different substituents, which was not included in the proposal documents, was also obtained by a facile method. In summary, several versatile new synthetic methods and potential functional silicon materials were obtained in this project.
