| Popis: | 98 This thesis presented the electrochemical studies of linear multinuclear metal string complexes and redox-dependent receptors for dioxoporphodimethene. Cyclic voltammetry (CV) is used to determine the half-wave potential (E1/2) of the metal string complexes. UV-Vis-NIR spectroelectrochemistry is used to confirm the formal potential (Eo’), the number of electron transfer in each redox process, and the oxidation states of metal string complexes. In the linear multinuclear metal string complexes, based on the electrochemical results and X-ray crystal structures, we are able to determine the oxidative or reductive centers for the electrochemical processes. We found that the redox couples in metal complexes are influenced by the number of metal ions, the oxidation states of the metal, the nature of the ligands and a variety of solvents. We designed dioxoporphodimethene and added different alcohols or acids to shift its redox potentials. Clearly H-bond perturbation is a strong interaction for achieving redox dependence in such systems. Furthermore, we use electrochemical methods to confirm the contention we met. |
