Abstract

Solution-based single-molecule conductance measurements of α,ω-bis(carboxylic acids) are conveniently performed using a high-boiling-point nonconducting ethereal solvent. First-principles calculations support experimental observations that linear oligoalkanes exhibit the expected exponential decay of conductance with length, whereas junctions comprising cyclic bridge hydrocarbons of different lengths and/or structures exhibit a similar conductance.

极性分子在非导电溶剂中的电导测量

基于溶液的α，ω-bis（羧酸）的单分子电导测量使用高沸点不导电的以太溶剂方便地进行。第一性原理计算支持实验观察，即线性低聚烷烃表现出预期的电导随长度的指数衰减，而由不同长度和/或结构的环桥碳氢化合物组成的结则表现出相似的电导。
