The Tokito-Kumaki laboratory is working to develop flexible electronic devices that utilize organic materials. In addition to being very thin and light, devices based on organic materials are bendable. They can be fabricated over large areas at low temperature using simple processes, and can be recycled easily. Innovations in new human-friendly application technology can be expected in areas that are in harmony with the people and the environment, such as healthcare.

In order to realize such devices, a set of basic technologies must be established:

(1) Create a molecule with the desired molecular structure and electronic states
(2) Depositing thin films using these molecules with the desired optical and
electronic properties
(3) Fabricate devices, such as transistors, using these thin films.

In addition, it is essential to ensure stability and reliability in flexible device through the research and development of electrode materials, dielectric materials and other functional thin films.

In our laboratory, a systematic approach to flexible device technology is being undertaken to achieve efficient devices that take full advantage of various organic materials.

Here, we believe that there is a need to bring together research results and knowledge from a wide variety of fields including organic chemistry, polymer science, analytical chemistry, semiconductor physics, electronics, biopolymer chemistry, and printing technology.

We want to nurture researchers who will practically contribute to society, by advancing both basic and applied research. In addition, we are collaborating with a number of corporate partners in research and development of new electronic device technology.
