Development of high performance organic semiconductors

To develop high performance organic semiconductor, not only molecular structure design of high carrier mobility organic semiconductor but to arrange the organic semiconductor molecules in highly ordered structure are indispensable.
Accordingly, we have been conducting the development of high performance organic semiconductors the following point of view.

1. To clarify relationship between molecular structure and carrier transporting capability of organic semiconductors through experimental research based on Gaussian Disorder Model and theoretical research based on the Marcus electron transfer theory and to establish molecular design of high performance organic semiconductors.
2. Regulation of the organic semiconductor molecules into highly ordered structure using self-organization.

Accordingly, we have been conducting the following research works.

1. Analysis of carrier mobility in organic semiconductors based on Marcus electron transfer theory and and Gaussian Disorder Model
2. Development of high carrier mobility organic semiconductors using self-oranizing nature of liquid crystalline
