| Outline of Final Research Achievements |
In this work, we synthesized well-designed π-conjugated polymers and oligomers containing Si- or Ge-bridged biaryl units in the backbone and explored their properties and electronic states. They were demonstrated to have enhanced conjugation as compared with the non-bridged congeners. These polymers and oligomers exhibited functionalities as photo-electron conversion materials. These results provide new concept of molecular design of functional materials based on the Si and Ge-bridged conjugated systems.
