Research subject summary 【 display / non-display

  • The physical properties of pai-conjugated molecules can be precisely controlled by structural modification. The goal of our projects is to create organic compounds with unique electronic, optical, and magnetic properties. In addition, we are developing precisely designed macromolecules such as dendrimers that can be thought of as highly organized nanostructures. From this point of view, we are conducting research on the development of efficient construction methods for pai-conjugated molecules and nanoscale molecules.
