“…As expected, the HOMO levels of the tetramers lie sufficiently low in energy to guarantee high open circuit voltages (V OC ) and the LUMOs sufficiently high to provide efficient electron transfer to the LUMO of the acceptor C 60 (≈-4.1 eV). [15] DCV4T derivatives 1-3 were used as the donor and C 60 as the electron acceptor in bulk heterojunction SMOSCs made by vacuum deposition with the following layer sequence: 15 nm C 60 evaporated on ITO-coated glass, followed by the photoactive blend layer of DCV4T 1-3 and C 60 , 2:1 by volume through co-evaporation at a substrate temperature of 70 °C, 5 nm of 9,9-bis{4-[di(p-biphenyl)aminophenyl]}fluorene (BPAPF), 50 nm of BPAPF p-doped with 10wt% NDP9, both as hole induced steric hindrance of the alkyl substituents. Derivatives 1 and 2 showed an almost planar conformation whereas ethyl derivative 3 displayed the highest out-of-plane torsional angles of 146.9° and 157.2° for the terminal thiophenes.…”

X-ray investigations on single crystals of a series of terminally dicyanovinyl-substituted quaterthiophenes and co-evaporated blend layers with C(60) give insight into molecular packing behavior and morphology, which are crucial parameters in the field of organic electronics. Structural characteristics on various levels and length scales are correlated with the photovoltaic performance of bulk heterojunction small-molecule organic solar cells.

“…Although the reason for these peaks is not fully understood, either the oxidation of the pyrrolidine groups or the electrostatic interaction between the positively charged ferrocene or zinc porphyrin groups with negatively charged fullerene cages in the film, or the oxidation/reduction of Pd particles in the film or Pdfullerene bound redox site of the complex could be responsible. Peak due to oxidation of the fullerene cage is not likely since the potential value of O 3 ' is much smaller than that of C 60 oxidation in solution [42]. It is also possible that peaks O 3 ' and R 3 ' are related to oxidation and reduction processes involved the outermost layers of the film.…”

Redox Active Two-Component Films of Palladium and Covalently Linked Zinc Porphyrin–Fullerene Dyad

et al. 2006

Redox active films have been generated electrochemically by the reduction of dyads consisting of fullerene C 60 covalently linked to zinc meso-tetraphenyloporphyrin, ZnPÀC 60 , and palladium acetate. The films are believed to consist of a polymeric network formed via covalent bonds between the palladium atoms and the fullerene moieties. In these films, the zinc porphyrin moiety is covalently linked to the polymeric chains through the pyrrolidine ring of the fullerene. The ZnPÀC 60 /Pt films are electrochemically active in both positive and negative potential excursions. At positive potentials, two oxidation steps for the zinc porphyrin are observed. In the negative potential range, electron transfer processes involving the zinc porphyrin and the fullerene entities are observed. Film formation is also accompanied by palladium deposition on the electrode surface. The presence of a metallic phase in the film influences its morphology, structure and electrochemical properties.

“…For C 60 , this irreversible electrooxidation is typical for many other supporting electrolytes [4]. Reversible one-electron oxidations were reported for C 60 and C 70 in 1,1,2,2-tetrachloroethane, TCE, [52]. For C 70 , a second irreversible electrooxidation in this solvent solution was also observed.…”

The electrochemical behavior of fullerene and fullerene derivatives are reviewed with special reference to their catalytic and sensor applications. Recent work on carbon nanotubes, used as catalyst supports in heterogeneous catalysis and sensor development is also presented. An overview of recent progress in the area of fullerene electrochemistry is included. Several cases of electrocatalytic dehalogenation of alkyl halides, assisted by the electrode charge transfer to fullerenes, are discussed. Research work on the electrocatalysis of biomolecules, such as hemin, cytochrome c, DNA, coenzymes, glucose, ascorbic acid, dopamine, etc. have also been considered. Based on the studies of the interaction of fullerenes, fullerene derivatives, and carbon nanotubes with other molecules and biomolecules in particular, the possibilities for the preparation of electrochemical sensors and their application in electroanalytical chemistry are highlighted.
