Organic electron‐acceptor materials play an important role in organic electronics, especially in organic bulk heterojunction (BHJ) solar cells. Recently, many non‐fullerene small molecular acceptors have been developed, in which aromatic fused‐imides were proven to be a promising family of excellent electron acceptors. We developed a series of acenaphtho[1,2‐k]fluoranthene‐fused diimides, AFIs (AFI1, AFI2 and AFI3), employing the Diels–Alder reaction as the crucial synthetic step. With electron‐withdrawing diimide groups in their large conjugated backbone, AFIs display a LUMO level around −3.50 eV. These AFI compounds were used as the electron acceptors to fabricate organic photovoltaic devices. The power conversion efficiency (PCE) of up to 2.37 % was achieved with a high open‐circuit voltage (V_oc) up to 0.96 V.

ena [1,2-k]荧蒽并二酰亚胺衍生物：分子结构与器件性能之间关系的研究

有机电子受体材料在有机电子产品中起着重要作用，尤其是在有机体异质结（BHJ）太阳能电池中。最近，已经开发了许多非富勒烯小分子受体，其中芳族稠合酰亚胺被证明是有前途的优秀电子受体家族。我们开发了一系列苊并[1,2的ķ ]荧蒽稠合二酰亚胺，AFIS（AFI1，AFI2和AFI3），采用Diels-Alder反应为关键合成步骤。在其大的共轭主链的吸电子基团二酰亚胺，AFIS显示的LUMO能级周围-3.50电子伏特。这些AFI这些化合物被用作电子受体来制造有机光伏器件。在高达0.96 V的高开路电压（V _oc）下，功率转换效率（PCE）高达2.37％。
