Outline of Final Research Achievements

In this project, we synthesized a series of compounds that would be the potential core building units for next-generation materials taking advantage of our previous achievements in the synthesis of cage or ladder silsesquioxanes. Among the target compounds, we successfully synthesized "Janus Cube", cubic silsesquioxanes with two different substituents on the opposite faces, "Eagle", two laddersiloxanes are fused up and down, and "Jelly Fish", cyclic silanols which contains long alkyl chains.
Regarding other two target compounds, continuing investigation is now in progress.
