通过使用Pd（PPh 3）2Cl 2催化的Suzuki反应，然后用FeCl 3环化，以高产率获得具有二萘嵌苯稠合芘结构的梯型多并苯（FP 2）和模型化合物（1c和2c）。所得模型化合物和聚并苯在常用溶剂中显示出理想的溶解性和高的热稳定性。在含有多并苯的稀二氯甲烷溶液中，在614 nm处观察到荧光峰。此外，所制备的模型化合物（2c）和聚并苯（FP 2）用作本体异质结（BHJ）太阳能电池中的受体，其中PTB 7-Th作为电供体电池。基于2c的太阳能电池的功率转换效率为3.25%。
Ladder‐type polyacene (FP2) and model compounds (1c and 2c) with perylene‐fused‐pyrene structures are achieved in high yields by using a Pd(PPh3)2Cl2‐catalyzed Suzuki reaction followed by cyclization with FeCl3. The obtained model compounds and polyacene display desirable solubility in commonly used solvents and high thermal stability. Fluorescence peak at 614 nm is observed in diluted CH2Cl2solution containing polyacene. Furthermore, the as‐prepared model compound (2c) and polyacene (FP2) are employed as acceptors in bulk‐heterojunction (BHJ) solar cells with PTB7‐Th as electrodonor cells. The 2c‐based solar cell demonstrates a power conversion efficiency of 3.25%.
