Electrosynthesis of Organic Compounds, their Electroanalytical Chemistry

Data

Official data in SubjectManager for the following academic year: 2023-2024

Topic

The aim of the course is to discuss about the electrochemical reactions of organic compounds, highlighting the effect of the used solvents, electrodes with different materials. The different groups of compounds will be introduced in this respect in details, especially the electrochemical halogenation and dehalogenation. The oxidation and reduction processes are mainly used in the electroanalytical methods, therefore the voltammetric and amperometric measuring methods will be shown in details. The shape and magnitude of electrode is also an important factor, especially microelectrodes serve as an appropriate tool for analysis of highly resistive media. The material of electrode is interesting due to the adsorption. The electrode reactions of organic compounds are along with exchange of protons so the related mechanisms are also important. In the electroanalysis the improvement of sensitivity and selectivity is essentially important and the electrode grafting methods are widespread, tiols bind strongly particularly to surface of gold. The material of carbon paste electrodes can be mixed with apolar organic compounds, on the other hand making intercalated graphene is possible. Through several examples the detectability of many organic compounds will be introduced. A special family of compounds, calixarenes will be highlighted especially in respect of electrode modifying materials.
