In the paper, the electrode system of the original TL/TSC measurement instrument is improved, which greatly facilitates sample exchange and increased liquid nitrogen's running and cooling speed. Through long time and repeated practice we finally find an effective method to prepare films. We've synthesized a new kind of organic photo-refraction material nitryl azobenzene grafting PVK and characterized it with IR spectra. We've also synthesized 5OCB and found the optimal mass ratio of PVK/5OCB/C60-49.8:50:0.2, and given the two-beam coupling testing result.
