Surface characterisation of 2.XB/HB_SAM. Electrochemical measurements were carried out in ACN/H₂O 99 : 1 containing 100 mM TBAClO₄ as electrolyte.

	Water contact angle (°)a	Γ b (10−10 mol cm−2)	E 1/2 vs. Ag|AgNO3b (mV)
2.XBSAM	68.4 ± 1.7	1.01 ± 0.18	193 ± 1
2.HBSAM	59.1 ± 1.1	1.15 ± 0.22	183 ± 2

^aErrors represent one standard deviation of 5 repeat measurements.

^bObtained from charge integration of the ferrocene peaks. Errors represent one standard deviation of independent experiments on three electrodes.
