| Research Abstract |
In this study, synthetic expansion, being based on boron-dibenzopyrromethene dyes, has been made to apply the related dyes to organic solar cells.
1) Synthesis of near-infrared light absorbing dye-cored thiophene dendorimers: we succeeded in the preparation of target systems where several branched oligothiophenes were incorporated into the core through Stille coupling reaction. Their photo-harvesting antenna effect has been evaluated.
2) Application to dye-sensitized solar cells: thienyl-cyanoacrylic acid unit which acts as both an anchor to TiO2-based electrode and an acceptor, was incorporated into boron-dibenzopyrromethene skeleton. The resulting dyes-loaded devices behaved as DSSC.
