Abstract: In this paper N,N'-Bis-(2-pyridine)-3,4,9,10-perylene tetracarboxylic diimide is synthesized,purified and crystallized, then element analysis, IR (C=O in ringed diimide shows the double peaks at 1708.8 cm-1,1664.5 cm-1) are analyzed. The UV-Vis absorption spectrum (maximum absorption wavelength at 526.00 nm) and fluorescent emission spectrum of α-crystal in a solution (maximum emission wavelength at 538.0 nm) are characterized by symmetry as a mirror image. The UV-Vis absorption spectrum in a film between 450 and 570 nm can indicate that α-crystal has stronger absorption peaks than β-crystal. It is obvious that the diffraction peak intensity of α-crystal are respectively at 25.5°, 26.3° in the X-ray diffraction pattern. The functional separate photoreceptors of α、β-crystal as charge generation material are made and time (T) (the certain surface potential is reached) respectively 45 s, 49 s,exposure H1/2 5.7 μJ·cm-2, 9.9 μJ·cm-2, residual potential 22 volt are tested after charging the sample and then using spectral light of 532 nm.
