A spiro[fluorene-9,9′-xanthene], often described as a “low-cost spiro,” has been functionalized with terminal diketopyrrolopyrrole units to generate a promising, three-dimensional non-fullerene acceptor. The new acceptor, coded as SFX1, was readily synthesized using the Suzuki cross-coupling reaction and was sufficiently soluble in a variety of commonly used, film-processing solvents such as chlorobenzene and o-dichlorobenzene. SFX1 displayed promising optoelectronic properties and the HOMO/LUMO energy levels complementary to the commercially available and commonly used donor polymers P3HT and PTB7. The joining of two high-potential building blocks – the spiro[fluorene-9,9′-xanthene] and diketopyrrolopyrrole – demonstrates a new strategy where the device performance [D : A 1 : 1.2 = 9.42% (D = PTB7)] validates its use as a potential, three-dimensional non-fullerene acceptor.

用二酮基吡咯并吡咯官能化螺[芴-9,9'-an吨]以生成有前途的三维非富勒烯受体
螺环[芴-9,9'-x吨]（通常被称为“低成本螺环”）已通过末端二酮吡咯并吡咯单元进行功能化，以产生有希望的三维非富勒烯受体。使用Suzuki交叉偶联反应可以轻松合成编码为SFX1的新受体，并且该受体应充分溶于各种常用的膜加工溶剂，例如氯苯和邻二氯苯。SFX1显示出有希望的光电性能和HOMO / LUMO能级与可商购和常用的供体聚合物P3HT和PTB7互补。结合使用两个高潜力的构建基–螺[芴-9,9'-x吨]和二酮基吡咯并吡咯–展示了一种新的策略，可以验证设备的性能[D：A 1：1.2 = 9.42％（D = PTB7）]用作潜在的三维非富勒烯受体。
