Electron-Donor−Acceptor Fullerene Derivative Retained on Electrodes Using SC3 Hydrophobin

We report a novel method of preparing electrodes coated with an electron-donor−acceptor fullerene. The tailor-made fullerene derivative with possible use for future photovoltaic devices was blended into a self-assembled SC3 hydrophobin matrix. Hydrophobin, a small, naturally occurring protein, has the remarkable property of adhering to almost any surface. The blend, immobilized by physisorption on glassy carbon electrodes, was electrochemically functional. The ease and rapidity of preparation, as well as the chemical and physical robustness of the system obtained, show that the biomimetic approach used for elaborating nanostructured materials might be of interest for technological applications.
