Outline of Final Research Achievements

For coordination frameworks, where paddlewheel type diruthenium(II,II) complex as an electron donor is bridged by organic linker, selective gas adsorption toward active gas, and gas-adsorption-induced electric/magnetic property modulation are expected due to electronic interaction between gas and framework. To demonstrate them, we designed and developed the measurement systems for structural, magnetic and electric properties of coordination frameworks under controlled atmosphere and temperature, which revealed that the gas-induced structural change and electronic interaction between gas and framework can be detected as electric/magnetic signal. Especially, significant enhancement of the electric conductivity under nitric oxide (NO) gas was demonstrated.
