Outline of Final Research Achievements

The polymer was synthesized by linking cage-silsesquioxane with 1,4-butanediol. In addition, a cage-type silsesquioxane having a functional group in which a beta-diketone group is substituted at the end of the thioether linker was synthesized, and a polymer was obtained by forming a complex with copper, aluminum, and titanium ions. On the other hand, a polymer in which the titanium phosphonate cluster was cross-linked was obtained by the reaction of titanium phosphonate cluster with diol. Furthermore, a new organic-inorganic hybrid material was obtained by hydrolyzing titanium phosphonate clusters in acetone or tetrahydrofuran. In particular, it was found that the form and properties of the product change greatly depending on the type of solvent to act as a catalyst for organic synthesis reactions and photocatalysts.
