  恶唑封端的共轭低聚物中的电荷传输和量子干涉效应

  摘要：

  单分子结中的电荷传输主要取决于用于将分子线连接到电极的锚定基团的化学特性。在这项工作中，我们报告了带有恶唑锚的共轭低聚物的电荷传输特性，重点是杂原子取代位置在末端恶唑基团中的作用。我们的结果表明，恶唑可作为形成稳定的金-分子-金连接的有效锚定基团。我们进一步观察了恶唑封端的亚苯基分子结中的量子干涉 (QI) 效应，包括间位取代苯环中的破坏性 QI 和对位取代苯环中含有两个末端具有相同化学组成的对位取代苯环的建设性 QI（即 O5O5 （5-恶唑基）或 O4O4（4-恶唑基）连接在两个末端）。出奇，与对位取代的类似物相比，具有非等价结构（即 O4O5 恶唑末端连接）的间位取代苯环显示出意外更高的电导率。这些结果表明，除了 pi 共轭核的芳基取代模式之外，恶唑末端分子中的电荷传输还由恶唑锚的杂原子取代位置决定。我们的结果进一步表明，具有均质恶唑键的共轭分子遵循量子电路规则，即 G_O4-p-O4/G_O4-m-O4
