Research Summary

With world's focus on environment and energy issues, our group aims to establish a novel principle of material sciences addressing these problems, through the development of unprecedented functional materials with precisely controlled structure and properties, from the molecular to nano-, meso-, or macroscopic level. The main research subjects include the development of (1) novel water photolysis catalysts entirely composed of ubiquitous elements, (2) organic ferroelectric materials for solution-processable high-density memory devices, and (3) graphitic soft materials based on the novel efficient method to exfoliate graphite into graphene sheets. The organic functional materials we develop are thoroughly investigated from the viewpoints of optical, electrical and morphological properties.
