Two polyschiff's base containing triarylated amine hol-transporting materials (PC-1, PC-2) that were never reported were synthesized by polycondensation. The materials with noncrystallization structure have fine thermal stability and cavity transportation properties. The structures of the condensed polymers were characterized by Infrared, UV-Vis and 1H NMR spectra. The crystalline actions of the condensed polymers that were synthesized from different solvents were investigated by X-ray diffraction technology. The result indicated that no crystalline phenomenon occurred when the solvent was dimethyl benzene. Through thermal gravity (TG) and differential thermal analysis (DTA), the thermal stability of the condensed polymers was performed in the presence of N 2. The ionization energy and advanced linear orbital level were calculated by quantum chemical initial calculation method. The results indicated that PC-1 and PC-2 have fine thermal stability and cavity transportation properties.
