Abstract

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.
