New Covalent and Supramolecular Tetraphenyporphyrin Hybrids As Abiotoc Redox-Macromolecules

We will report on the synthesis of various families of new hybrid-architectures where tetraphenylporphyrines are combined with other redox-active molecules such as fullerenes. In some cases model compound for globular redox proteins have been developed by incorporation of polar and apolar dendritic architectures. Depending on the microenvironment provided by the nature of the dendritic shell the electron-transfer- and coordination properties can be tuned as demonstrated for example by electrochemistry and time-resolved spectroscopic methods. Also nanoparticles such as ZnO have been functionalized with new tetraphenylporphyrin derivates and the use of such materials in dye-sensitized solar cells will be presented.
