Research Topic

Development and investigation of new functional materials for molecular architectonics

Research Aim

Our objective is to achieve the scientific results that will become the foundation toward the application of organic molecules in electronics, starting with the development of functional π-electron systems based on synthetic organic chemistry and structural organic chemistry. From this point of view, this research designs and develops the molecular components essential to the realization of molecular architectonics and elucidates physical properties and functions based on molecular structure.

Role and Need in the Group

The role of this research area is designing new materials in the field of molecular architectonics. Molecules to be created in this research can contribute to obtaining new insights into molecular architectonics through physical property measurements, device evaluation, and theoretical calculations.

Research Content

a01-3.jpgWe will focus on developing anchor molecules aimed at explaining local electronic states and regulating the charge transport capability and molecular conduction in a metal-electrode–organic-molecule interface. In addition, we plan to utilize their characteristics to further develop molecular architectonics by applying them to molecular nanoelectronic materials and integrated functional materials.
