Two new building blocks of perylene-embedded benzoazoles containing both rigid 2D-conjugated aromatic rings and flexible branched alkyl chains were designed and facilely synthesized in high yields for organic solar cells (OSCs). With a typical acceptor of diketopyrrolopyrrole, small molecular OSC donors constructed in an acceptor-fused donor–acceptor motif exhibit excellent solubility, stability, and light absorption with tunable frontier orbitals, leading to a power conversion efficiency of up to 2.88% in preliminary OSCs.

小分子有机太阳能电池用ylene嵌入的苯并恶唑的合成及应用

设计并制造了两个新的既包含刚性2D共轭芳环又包含柔性支链烷基链的per嵌入的苯并恶唑，并以高收率轻松合成了有机太阳能电池（OSC）。使用典型的二酮基吡咯并吡咯受体，以受体融合的供体-受体基序构建的小分子OSC供体表现出优异的溶解性，稳定性和光吸收性以及可调谐的前沿轨道，在初步OSC中的功率转换效率高达2.88％。
