The redox potentials of 4,4’-dimethyl-N’N’-alkylidene bridged 2,2’-bipyridiniumsalts derivatives (DBPAs) can be controlled by changing the N, N’-alkylidene bridge length which changes the conformation of the DBPAs.. In this paper, the torsional angles between the two pyridine rings and the molecular energy of DBPAs are calculated using a PC based software package (AccuModel 1.2). The relationship
4,4'-二甲基-N'N'-亚烷基桥接的 2,2'-联吡啶鎓盐衍生物 (DBPA) 的氧化还原电位可以通过改变 N, N'-亚烷基桥长度来控制,从而改变 DBPA 的构象.. 在本文中,两个吡啶环之间的扭转角和 DBPA 的分子能量是使用基于 PC 的软件包(AccuModel 1.2)计算的。讨论了扭转角与N,N'-亚烷基桥长度之间的关系。DBPA 的分子能量也可能与扭转角(或 N, N'-亚烷基桥尺寸)有关。已经合成了一些 DBPA 并测量了它们的氧化还原电位。乙烯和丙烯桥接的 DBPA 之间的电位差大到足以通过双层修饰电极制成有机二极管。
