Abstract: 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.

Abstract: Organic devices comprising an organic semiconducting acceptor motif coupled to a donor motif. Examples include IOTIC-2F, ITOTIC-2F, COTIC-4F, and SiOTIC-4F as acceptor materials. The acceptor materials have narrow bandgap (1.1 eV-1.3 eV), strong near-IR absorption and high solar cell EQE in near infrared (IR) region. The acceptor materials may also be used as the absorbing/light sensitive region in an IR photodetector.
