在有機光電二極體(OPDs)和生物識別方面，吸收波長可達1000nm的近紅外(NIR)小分子受體具有吸引力。在這項研究中，我們將IEICO-4F作為PffBT4T-2OD：PC71BM基OPDs的第三個成分，以提供高效的NIR響應，同時極大地抑制反向偏壓下的漏電流。

Near-infrared (NIR) small-molecule acceptors that absorb at wavelengths of up to 1000 nm are attractive for applications in organic photodetectors (OPDs) and biometrics. In this study, we incorporated IEICO-4F as the third component for PffBT4T-2OD:PC71BM-based OPDs to provide an efficient NIR response while greatly suppressing the leakage current at reverse bias.
