X‐ and H‐shape two‐dimensional (2D) conjugated oligomers (X‐ and H‐mers) and relevant model compounds have been synthesized through the introduction of different conjugated segments at the 9,10 and 2,6‐positions of anthracene, and their properties were studied in detail. Comparing with the model compounds, the X‐ and H‐mers are featured with broader absorption spectra and narrower energy bandgaps.
通过在蒽的9,10和2,6位引入不同的共轭链段,合成了X和H形的二维(2D)共轭低聚物(X和H-mers)以及相关的模型化合物,并对其性质进行了详细研究。与模型化合物相比,X-和H-mers具有更宽的吸收光谱和更窄的能带隙。对最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)的计算研究也表明,这些X-和H-mers是二维共轭的。以[6,6]-苯基-C61-丁酸甲酯(PCBM)为受体材料的固溶体异质结(BHJ)太阳能电池表现出高达0.53%的功率转换效率(PCE)。
