摘　　要：本工作合成了一种新的具有给体-受体结构的长碳链有机分子,2,3-二(十六烷硫基)-5-(4′-硝基苯亚甲基)-1,4-二硫代-2-环戊烯,对其单分子膜的成膜性能进行了研究。在适宜条件下制备了单层及多层LB膜.通过电子衍射、X射线衍射、紫外-可见吸收光谱等手段对LB膜的结构进行了表征.实验结果表明,这种化合物的成膜性能很好.单分子层膜的二次谐波测试表明该发色团分子具有较好的二阶非线性光学性.A novel organic molecule with donor-acceptor structure and long-chain was synthesized. Its stable Langmuir films were formed at the air-water interface. Langmuir-Blodgett (LB) films with a Z-type mode were deposited at appropriate experimental conditions. The LB films were characterized by UV-visible spectroscopy, electron diffraction and small angle X-ray diffraction measurements. The nonlinear optic behavior of its monolayer was evaluated from the second harmonic generation.
