摘要：
Self-assembled monolayers (SAMs) of arylene-ethynylene oligomers that incorporate electron-accepting 9-fluorenone and 9-[(4-pyridyl) methylene] fluorene units in the backbone exhibit symmetrical current - voltage ( I - V) characteristics, but rectifying junctions with current ratios of 20 - 80 at +/- 1 V have been obtained by protonating these wire-like molecules and ionically coupling with anionic donors.
