Fluorinated 1,8-naphthalimides: Synthesis, solid structure and properties

Three fluorinated 1,8-napthalimides were synthesized from acenaphthene. Their structures were characterized by NMR and EI-MS analyses. The structures of compounds 1b and 1c were also confirmed by X-ray diffraction analysis, which showed that they possessed different packing models. Their optoelectronic properties were investigated. The results indicated that all of the naphthalimides possess good solubility and low LUMO energy level, which make them good solution processing candidates in n-type semiconductor. (C) 2014 Jun Yin.
