The first two asymmetric-indenothiophene-based donor-acceptor copolymers (PITBT and PITFBT) are prepared through Stille coupling reactions between distannyl indenothiophene and brominated benzothiadiazole derivatives. The best performing solar cell fabricated from PITFBT exhibits a power conversion efficiency of 9.14% which demonstrates a great potential of the asymmetric indenothiophene for high-performance copolymers.
两种基于首例不对称茚并噻吩的给体-受体共聚物（PITBT 和 PITFBT）是通过二芳基二锡基茚并噻吩与溴代苯并噻二唑衍生物之间的 Stille 偶联反应制备的。由 PITFBT 制成的性能最佳的太阳能电池的功率转换效率为 9.14%，这表明不对称茚并噻吩在高性能共聚物中具有很大的潜力。
