利用自组装技术在金电极表面构造了具有不同前端健长度偶氮苯功能化的单分子膜体系：Au／S（CH2）nNHCO-N＝N-OCH2CH3（n＝2，3，4，6）．研究结果表明，仍氮苯到金电极的表现电子转移速率随它们之间的距离长度的增加而呈指数性的下降趋势．基于Marcus电子隧穿理论，得到了此自组装膜体系的长程电子隧穿系数ρ＝（1．35±0．2）／CH2在和可逆电活性分子自组装膜体系及理论计算相比较的基础上，从偶氮苯分子自组装膜结构与电子转移过程的关系角度对这一结果进行了分析和说明．
The self-assembly technique was used to fabricate a monolayer membrane system with azobenzene functionalization on the surface of gold electrode. Au / S (CH2) nNHCO-N = N-OCH2CH3 (n = 2,3,4,6) . The results show that the electron transfer rate of benzidine to gold electrode decreases exponentially with the increase of the distance between them. Based on Marcus electron tunneling theory, the long-range electron tunneling coefficient ρ = (1.35 ± 0.2) / CH2 of this self-assembled monolayer system was obtained and compared with the reversible electroactive molecule self-assembled monolayer system and its theoretical calculation On the azobenzene molecular self-assembled film structure and the relationship between the electron transfer process of this result was analyzed and explained.
