Seeking a Postdoctoral Researcher or Research Scientist (W22267)


Emergent Molecular Function Research Team
RIKEN Center for Emergent Matter Science
(Team Leader: Kazuo Takimiya)

Research Field

Our laboratory focuses on the development and application of functional π-electron compounds, ultimately aiming to explore new frontiers in materials science by investigating their molecular scientific aspects and molecular design principles, as well as their application to electronic devices.

Specifically, our research activities range from the development of materials by synthetic chemistry and the fabrication and evaluation of devices such as organic transistors and solar cells to the development of molecular design and thin-film fabrication processes, structural analysis, and characterization of physical properties.
