会议地点:化学学科楼 A508

报告人简介:Ryo Tsunashima completed his PhD under the supervision by Professor Takayoshi Nakamura at Hokkaido University in 2007. Following that, he worked as a research associate in Professor Leroy Cronin’ s group, University of Glasgow. In 2009, He took his current position as an associate professor at Yamaguchi University, and his research interest mainly focuses on molecular based solid-state chemistry of molecular polynuclear metal complex such as polyoxometalate, coordination compounds, and organic molecules. Recently, one of his great interests is solid-solution of the molecular ionic crystals.

报告内容简介Solid-solution is common materials strategy to tuning properties and functionality of the inorganic solids, where differences in radius of ions are below 15% kwnon as Hume-Rothery rules. Structural similarity is key requirement for high solubility in the lattice. Thus, molecular crystals are not the better solid-state materials to be dissolved at the molecular level. The easier the molecule is to be dissolved in the lattice, the less dramatic the change in the physical properties and characteristics of the resulting solid solution. We have been developped solid-solution of the heteromorphic molecules which are usually not form solid solution. Solid-solution methology for metal-free perovskite compounds will be discussed with our recent papers.
