Figure 1. — Realized surface coatings. (A) Overview of the examined self-assembled monolayers with different functional groups. The modifications NH₂, pyridinium (Py), and SO₃H are synthesized via a bromine monolayer (Br), which is substituted by azide (N₃) and reduced to NH₂, substituted by Py or thioacetate (SCOCH₃), and oxidized to SO₃H. Carboxylic acid groups (COOH) are generated via oxidation of a monolayer with terminal vinylic groups (CH=CH₂). (B) Infrared spectra of SAMs recorded via DRIFT spectroscopy. (C) Water contact angles of final modifications (blue) as well as their intermediate SAMs (gray). Median ± interquartile range (n ≥ 8). SAM, self-assembled monolayer.
