Revisiting the determination of full steady-state coverage of redox centers on self-assembled monolayers

This work establishes an experimental estimation of the full steady-state coverage of redox centers on self-assembled monolayers. The results demonstrate that the assessment of the full surface coverage and the adsorption kinetic from a Langmuir model impose drastic experimental conditions.

► The full steady-state coverage on SAMs is estimated from electrochemical data.
► This assessment imposes drastic experimental conditions.
► The adsorption free energy is clearly independent of the chain length.
► The rate of adsorption increases monotonously with chain length.
