| Outline of Final Research Achievements |
We developed a series of functional pi-electronic materials using our original pi-skeleton from viewpoints of control of highly dimensional orientation of compound in the solid state. For example, HND-Azulene bearing quasi-planar skeleton and azulene core was demonstrated to exhibit high performance as p-type semiconductor in perovskite solar cells. the cells using HND-Azulene improves the power conversion efficiency by 1.2 times compared to that with standard materials. We also designed and synthesized T-shaped skeleton, which was found to be useful as an electron-accepting unit in D-A materials in organic photovoltaics. Moreover, the expanded quasi-planar skeleton can be used as a key skeleton for CPL materials, which allow the emission color tuning over the whole visible region.
