Outline of Final Research Achievements

In this project, we aimed to create quantum condensed phases of confined molecules or atoms and to elucidate their behavior and properties, in nano-sized porous space of porous coordination polymers. During the research period, we mainly carried out the following; (1) elucidation of behavior of confined NO and I2 molecules in the pore, (2) induction of ortho-para quantum phase transition of nuclear spin isomers of H2 using inner electric field of the pore, and (3) creation of high-temperature quantum condensed phase of He. Dynamics and physical properties of confined guest molecules or atoms and guest-guest or host-guest interactions were examined in detail, by using in situ measurements of temperature dependences of magnetization, X-ray diffraction, and Raman and IR spectra under pressure-controlled guest atmosphere.
