Abstract: A method for producing an organic non-fullerene electron transport compound includes mixing naphthalene-1,4,5,8-tetracarboxylic dianhydride and an amine compound in dimethylformamide. The method also includes heating the mixture to a temperature greater than or equal to 70° and less than or equal to 160° C. for an amount of time greater than or equal to 1 hour and less than or equal to 24 hours. The method further includes isolating an organic non-fullerene electron transport compound reaction product.
