苯胺三聚体，五聚体和七聚体的电导已被测量在分子结作为分子的氧化态的函数，通过电化学电位控制下进行测量。有效电子衰变长度太小，与中性分子中的简单隧道传输不一致，而在氧化分子中甚至更小。因此，这些分子可以作为相对高的电导链接，即使在金属行为所需的链间跳跃的情况下。(c)2007年，美国物理学会。
The conductance of aniline trimers, pentamers, and heptamers has been measured in a molecular junction as a function of the oxidation state of the molecules by making measurements under electrochemical potential control. The effective electronic decay length is too small to be consistent with simple tunnel transport in the neutral molecule and is even smaller in the oxidized molecule. Thus these molecules can act as relatively high conductance links even in the absence of the interchain hopping required for metallic behavior. (c) 2007 American Institute of Physics.
