Abstract

<jats:title>Abstract</jats:title> <jats:p>The effect of molecular packing density on the electron transfer kinetics in an azobenzene self-assembled monolayer on gold was investigated for the first time by controlling the assembling time. The apparent electron transfer rate constant (kS) showed a gradual decrease with increasing the molecular packing density, which can be well understood in terms of a structural inhibition occurred in the closely packed monolayer on the reduction/oxidation of azobenzene.</jats:p>
