摘要
A recent model for molecular rectification has focused upon asymmetric alkyl tunnelling barriers that link the electrodes to a conjugated unit 1 but experimental data reported here are contradictory: self-assembled mono-layers (SAMs) exhibit symmetrical current-voltage characteristics when squaraine chromophores are located at one electrode and isolated from the other by extended alkanethiolate tails.
