The Reaction of Aryl Radicals with Metallic Electrodes.

Functionalization of nanomaterials with aryldiazonium salts

“…Obviously, these are surface chemical reactions but, at that time, they were not defined as such. The electrochemical investigations continued sparsely in the 1960s and 1970s for various purposes until the early 1980s when a Norwegian group, led by Vernon Parker [32], observed the passivation of metal electrodes upon electrochemical reduction of 5 1-naphtalenediazonium tetrafluoroborate (NDT). They stated that deactivation of electrodes during oxidation or reduction of organic compounds is not an unusual observation and the fact that the phenomenon occurs during the electrochemical reduction of NDT is not of interest.…”

Ground State Electronic Interactions in Macrocyclic Fullerene Bis‐Adducts Functionalized with Bridging Conjugated Oligomers

“…[16] Disappointingly, all attempts to perform stepwise coulometric titration with 1, 2, 13, and 14 failed due to the instability of the oxidized species. [17][18] Fortunately, oxidized species derived from compounds 1 and 14 could be generated chemically in THF/nitrobenzene (9:1) by addition of Fe(ClO 4 ) 3 . Their formation was followed by absorption spectroscopy.…”

Voltammetric Determination of Anti-Hypertensive Drug Hydrochlorothiazide Using Screen-Printed Electrodes Modified with L-Glutamic Acid

“…The potential window was set between -0.4 and 0.8 V at a 100 mV s −1 scan rate. As it can be seen in Figure 2, for SPCE/EGA after electrografting a current decrease, in comparison to bare SPCE, is observed, which can be attributed to the formation of a blocking layer [45]. For both SPCE/PGA and SPCE/EGA, the immobilization of L-glutamic acid via electropolymerization and covalent binding, respectively, resulted in both, higher current peaks in comparison with bare SPCE and a better reversibility of the couple Fe(II)/Fe(III), due to their enhanced surface area.…”
