The invention discloses a compound containing staggered biphenyl center and a preparation method thereof. The new compound containing staggered biphenyl center is characterized by being prepared from using 2,2',5,5'-biphenyl tetracarbonychloride as a center unit to react with a side chain unit through a condensation method. The rotatable staggered biphenyl structure reduces intermolecular interactions, enables a material to transform from a crystalline state to an amorphous state while keeping heat resistance, mechanical strength and functionality of the material, reduces a material processing temperature, increases material solubility in an organic solvent, improves the processing performances of the material and endows novel functions and purposes at the same time. |
