The properties of molecular electronic devices can be tuned by tailoring the structures of the molecules from which they are built. Researchers now show that two closely related molecules — each containing a string of four aryl groups — behave very differently when strung between gold electrodes, with the non-symmetrical structure leading to diode-like behaviour.
