“…For instance, when the platinum surface with adsorbed bipyridine or thiophene interacts with a hydrogen cation, the probability of proton adsorption on platinum increases, [28] leading to enhanced platinum activity in reactions involving hydrogen cation. Based on the information provided, platinum can be activated by adsorbed molecules, including derivatives of bipyridine and thiophene, in certain (electro)catalytic reactions.…”

Several new derivatives of 2,2′‐bipyridines with a spacer group separated from the 2,2‐bipyridine fragment, namely, an ethynyl fragment, were obtained using the Sonagashira cross‐coupling reaction. The resulting derivatives were physically adsorbed on platinum electrode and were then used as activators of the catalytic activity of a platinum electrode in the reaction of cholesterol electrooxidation in an acetonitrile medium. Sensitivity, limit of detection and detectable concentration range were calculated, and the best results was established as 6.2±0.6 μA/mM, 0.08 mM and 0–0.3 mM, respectively. These results show that the prepared compounds adsorbed on platinum electrode are perspective systems for developing of new enzymeless cholesterol sensor based on them.
