| Outline of Final Research Achievements |
New tethering units that are more stable thermally and chemically than the previous compounds were developed. Polymers comprised with them were synthesized and it was found that the polymers have H-type stacking conformation. In addition to H-stacking polymers, polymers having structure of J-stacking, staggered stacking and alternatively staking of different pi-units were developed and their optical properties were investigated. New cross-stacking polymers that have pi-units extended to polymer chain vertical axis were developed and they exhibited higher hole-transferring ability than previous folded polymers. Investigation of properties of thin-layer photovoltaic device comprised with folded pi-stacking polymers and ability of singlet-fission in them is underway in our laboratory.
