Research Subject
Syntheses of electronic active π conjugated molecules and investigation their function.

研究の背景 Background


Electronic active π conjugated molecules have been extensively studied since they have been used as functional materials such as dyes, organic electronic devices, sensors. As with development of new π electronic systems, control of molecular assembly of π conjugated molecules is also important, which should improve bulk physical properties and lead new function.

研究の目標 Outcome


My research is focused on development of electronic active π conjugated molecules and investigation of their function. I am now investigating redox systems which change their electronic/molecular structure upon electron transfer, liquid crystalline materials with electronic active aromatic core, and liquid crystalline materials which change ferroelectric properties driven by molecular motion toward electric field.

Fig.1. Dynamic redox system based on quinacridone-based dye. Upon redox reaction, color, molecular structure and biradical properties could be changed. Fig.2. Electron-deficient azaacene derivatives form thermotropic liquid crystals. The liquid crystal phases were effectively stabilized by cooperative intramolecular noncovalent interactions.
