| 英文摘要 | Two conjugated polymers, PBDT-TBT and PBDT-TTBT, were designed and synthesized. PBDT-TBT has a zigzagged chain conformation (Z-type), while PBDT-TTBT has a linear chain conformation (L-type). The results show that the polymer chain conformation significantly affects the optoelectronic properties of the polymers. With the conformation change from Z-type to L-type, the J-aggregation of the polymer was enhanced greatly, i.e. PBDT-TTBT shows a much more prominent absorption shoulder peak at the long wavelength direction compared to PBDT-TBT. In the X-ray diffraction analysis, it was found that the L-type polymer shows much stronger crystallinity than the Z-type polymer. Benefiting from the enhanced inter-chain pi-pi stacking effect, the blend of PBDT-TTBT/PC71BM showed higher hole mobility compared to the blend of PBDT-TBT/PC71BM. The power conversion efficiencies (PCEs) of the polymer solar cells based on PBDT-TTBT/PC71BM and PBDT-TTBT/PC71BM are 6.3% and 4.9%, respectively. These results clearly reveal that the backbone conformation is an important issue for improving the intermolecular interaction of conjugated polymers, and hence provides a guideline for the molecular design of conjugated polymers. |
