Non-fullerene electron acceptors for highly efficient organic photovoltaic devices are described. The non-fullerene electron acceptors have an extended, rigid, &#x3c0;-conjugated electron-deficient framework that can facilitate exciton and charge derealization. The non-fullerene electron acceptors can physically mix with a donor polymer and facilitate improved electron transport. The non-fullerene electron acceptors can be incorporated into organic electronic devices, such as photovoltaic cells.

Non-fullerene electron acceptors for organic photovoltaic devices

Novel acenaphthylene imide-derived semiconductor materials, including small molecule compounds, polymers and oligomers. Also provided are methods for making the novel semiconductor materials and the use of the novel semiconducting materials in electronic or optoelectronic device. In some embodiments, the novel semiconducting materials are used as n-channel component in organic field-effect transistors as well as complementary electronic circuits including inverters. High mobility can be achieved.
