  • ULTRA NARROW BANDGAP NON-FULLERENE-ACCEPTOR BASED ORGANIC ELECTRONICS
    Publication number: 20230132149
    Abstract: Ultra-narrow bandgap Non Fullerene Acceptors (NFAs) comprising an A-D-A?-D-A structure or an A-D-A?-D?-A?-D-A structure were designed, synthesized, and characterized (where A, A? are organic acceptor moieties and D and D? are organic donor moieties). Exemplary NFA materials have narrow bandgap (0.86 eV-0.99 eV). Photovoltaic devices and Near Infrared photodetector devices based on these compositions above were synthesized with controlled amounts of solvents and additives. A photodetector having a specific detectivity of 2.41×1012 Jones (D*) at a wavelength of 1040 nm was achieved.
