Abstract

The invention belongs to the technical field of bipolar semiconductors, and discloses a semiconductor material, a field effect transistor device, a bipolar semiconductor and application, and the semiconductor material is a crystal material which has a close-range strong pi-pi effect and is formed by a cross dipole type molecule accumulation mode; and the crystal material is formed by orderly arranging D-A-D type molecules AzoO2-PDI which are subjected to chemical modification and have donor and receptor structures. The D-A-D type flying fish-shaped molecule AzoO2-PDI is obtained through ingenious molecular design and chemical modification. The the weak electron donating effect and the steric hindrance effect of the diazophenol oxygroup serving as a side group modification group are respectively utilized to achieves the dual purposes of reducing energy gaps, finely adjusting the front line orbit distribution and promoting the injection of electrons and holes, forming cross dipole type molecular accumulation with strong pi-pi action to strengthen the superposition of wave functions and electronic coupling among PDI cores and promoting the effective transmission of the electrons and the holes from two levels of molecules and crystal materials.

Description
