This approach mimics in some way dye sensitized solar cells because porphyrin/fuUerene clusters serve as sensitizers for buffer tin oxide (Sn02). At the same time, mixed fuUerene/polymer nanostructures resemble bulk heterojunction solar cells since donor (porphyrin) and acceptor (fullerene) molecules are blended together in the active layer. 

Kazemi et al. [121] reported the electrochemical fabrication of a conducting polymer of 5,10,15,20-tetra(4-sulfophenyl) porphyrin-nickel as a nanostructured electrocatalyst for hydrazine oxidation. An electrode modified with this electrocatalyst provided a detection limit of 0.11 pmol and a sensitivity of 1 pA L pmoF for the determination of hydrazine, and showed good stability and reproducibility.
