The invention belongs to the technical field of eutectic semiconductor materials, and discloses a D-A type acene-perylene bisimide eutectic crystal, an organic field effect transistor and a preparation method and application of the D-A type acene-perylene bisimide eutectic crystal and the organic field effect transistor. As a bipolar semiconductor material, the D-A acene-perylene bisimide eutectic crystal shows balanced bipolar with excellent performance, has an ultrahigh on-off ratio, and shows great application value in the aspect of electronic circuits.

The application provides a long acene derivative molecule containing a seven-membered ring and a preparation method thereof. The structure is shown in formula I, formula II or formula III. The application takes a cycloaddition reaction, a double coupling reaction and other reactions as key steps, and long acene derivative molecules containing a seven-membered ring shown in formula I, formula II and formula III are simply and efficiently synthesized. The method has the advantages of high efficiency and simplicity, short synthesis period, macro preparation of raw materials, synthesis of novel non-benzene polycyclic aromatic hydrocarbons containing a seven-membered ring which cannot be obtained by traditional methods and the like. The novel non-benzene polycyclic aromatic hydrocarbons containing a seven-membered ring synthesized by the application have unique optical physical and electrochemical properties and good photoelectric functions.
