| Oligothiophenes constitute an important class of organic materials with a wide range of potential applications. Despite the apparent importance of this class of compounds, their electrochemical properties remain scattered in the literature. To make things more complex, many of the published data were carried out under a wide range of experimental parameters such as solvents, scan rates, supporting electrolytes, concentrations and reference electrodes. We will report the cyclic voltammetry measurements for a series of oligothiophenes with length up to hexamers endowed with various electron acceptor and donor groups placed at various positions. These are measurements carried out under the same experimental conditions. Trends in the effect of the introduced structural modifications on the observed redox behavior, and therefore the relative positions of the HOMO-LUMO levels of oligothiophenes, will be presented. |
