  Narrow bandgap n-type small molecules are attracting attention in the near-infrared organic optoelectronics field, due to their easy tunable energy band with a molecular design flexibility. However, only a few reports demonstrate narrow bandgap non-fullerene acceptors (NFAs) that perform well in organic solar cells (OSCs), and the corresponding benefits of NFA photodiodes have not been well investigated in organic photodetectors (OPDs). Here, the ultra-narrow bandgap NFAs CO1-4F, CO1-4Cl and o-IO1 were designed and synthesized for the achieved efficient near-infrared organic photodiodes such as solar cells and photodetectors. Designing an asymmetrical CO1-4F by introducing two different π-bridges including alkylthienyl and alkoxythienyl units ultimately provides an asymmetric A-D′-D-D″-A molecular configuration. This enables a delicate modulation in energy band structure as well as maintains an intense intramolecular charge transfer characteristic of the excited state.

  窄带隙n型小分子在近红外有机光电子领域引起了关注，这是因为它们具有易于调节能带的分子设计灵活性。然而，只有少数报道表明在有机太阳能电池（OSCs）中表现良好的窄带隙非富勒烯受体（NFAs），并且NFA光电二极管的相应优势在有机光探测器（OPDs）中尚未得到很好的研究。在这里，为了实现高效的近红外有机光电二极管，如太阳能电池和光探测器，设计并合成了超窄带隙NFAs CO1-4F、CO1-4Cl和o-IO1。通过引入包括烷基噻吩基和烷氧基噻吩基在内的两种不同π-桥接体，设计了一个不对称的CO1-4F，最终提供了一个不对称的A-D′-D-D″-A分子结构。这使得能带结构得以精细调制，同时保持了激发态的强烈分子内电荷转移特性。
