D-A type near-infrared organic light-emitting material as well as preparation method and application thereof

The invention relates to a D-A type near-infrared organic light-emitting material and a preparation method and application thereof. Naphthothiazole quinoxaline is introduced in a closed-loop mode to serve as a rigid large-plane electron acceptor structure. A strong electron donor structure with a high HOMO energy level is selected, and the intermolecular torque is enhanced through the change of aconnection position, so that the separation of the HOMO/LUMO energy level is effectively enhanced. The invention provides a series of D-A type near-infrared organic light-emitting materials containingnaphthothiazole quinoxaline structural units. The raw materials are easy to obtain, the preparation process is simple, the reaction process is easy to control, and the product is easy to separate, high in yield and high in purity; the material shows good thermal stability, and film state luminescence is in a near-infrared region; and important application potential is shown in the aspect of near-infrared organic light-emitting devices.

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.
