Outline of Research at the Start |
The project targets the synthesis of new crystalline materials with two-dimensional-layered hybrid architectures comprising C60 and polyaromatic hydrocarbon building blocks. These strongly-correlated Mott insulating phases will be further chemically (via alkali metal intercalation) and physically (via pressure application) manipulated to turn them into metals and superconductors.

Outline of Annual Research Achievements |
The project has been targeting the synthesis of new crystalline materials with two-dimensional-layered hybrid architectures comprising C60 and polyaromatic hydrocarbon building blocks. This has been successful for the polyaromatic hydrocarbon, triphenylene. The resulting strongly-correlated Mott insulating phases have been structurally characterized down to cryogenic temperatures and reveal unique architectures and a variety of phase transitions. They have now been chemically manipulated to afford crystalline reduced materials with two-dimensional architectures. Their properties focusing on metallicity and superconductivity are being actively pursued.

Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The purpose of the project was to assemble unsaturated hydrocarbons of varying size, shape and electronic state together with C60 to generate new molecular electronic materials. This has been successfully carried out to an advanced stage. In particular, the resulting low-dimensional strongly correlated architectures are being manipulated chemically to investigate the possibility of switching on superconductivity.

Strategy for Future Research Activity |
The research plan for the future years consists of two integrated components. (A) Chemical synthesis. We will create hybrid co-crystals of PAHs of varying size and shape and C60 and initiate attempts to intercalate them with alkali metals to produce electron-doped systems. (B) Structural analysis. We will carry out precise structural determination at low temperature and/or high pressure with synchrotron X-ray and neutron diffraction.
