Outline of Final Research Achievements

In this project, hybrid nanomaterials composed of silsesquioxane and germanium cluster as a core and organic capping reagents as a corona were synthesized. The germanium cluster composed of a 3-D G-Ge network capped with organic reagents. Phenyl-GeCs, which contained a phenyl group capping reagent formed the most stable monolayer in the synthesized materials because of the pi-pi interaction between the phenyl groups. The monolayer can be transferred onto a solid substrate using the Langmuir-Schaeffer method, and atomic force microscopy (AFM) images revealed a uniform film (root mean square roughness of 0.6 nm) of 3-4 nm in thickness. Furthermore, a multilayer phenyl-GeC film was prepared by repeating the deposition process.
An amphiphilic silsesquioxane (DDSQ-4DEG) was synthesized based on polyhedral silsesquioxane. DDSQ-4DEG formed a stable monolayer at the air-water interface. The monolayer property of DDSQ-4DEG can be tuned by introducing substrates onto water sub phase.
