Self-assembled monolayers (SAMs) of alkoxycyanobiphenyl thiols on gold-A study of electron transfer reaction using cyclic voltammetry and electrochemical impedance spectroscopy

Self-assembled monolayer formed by liquid crystalline molecule of thiol-terminated alkoxycyanobiphenyl mediates electron transfer between Au electrode and [Ru(NH3)6]2+/3+ when the alkyl chain length is short and retards the process when the chain length is longer.
