Emergent Properties of Correlated π-electrons in Flexible Assembly of Organic Nanostructures

The main research subjects in this group are the experimental investigations of the organic molecular conductors. The characteristic properties of the organic materials are multiple fl exibilities owing to the assemble structure of nanometer-size molecules. This fl exibility comes up recently for developing the organic electronic devices. We explore the fundamental electronic properties of the organic molecular materials which have wide range of the ground states from the superconductivity to the insulating states resulting from the strongly correlated electrons in the molecular π-orbital. Such features are closely connected to fl exible and multiple degrees of freedom in charge, spin, molecular lattice and molecules themselves. We are actively studying on the interesting and important issues in the condensed matter physics from the viewpoints of the characteristic fl exibility of the organic molecular materials.
