“…Anyway, there are reasonable indications that heating ofC 60 Cl x can, at least partially, regenerate C 60 in agreement with our previous work (12). However, in this case the ratio A 260 /A 329 = 7.3 instead of the expected 3.4 of C 60 .…”

“…Our recent research efforts in this field are directed to the identification and study of the early intermdiates formed by the interaction between C 60 and ozone (8) as well as the chemical structure of the C 60 ozopolymer which recalls the structure of oxidized graphite, at least to a certain degree of similitude (9). Finally, another C 60 derivative of interest is the product of photochlorination (10,11) which can be described by the minimal formula C 60 Cl x with x = 18 maximum, as we have shown recently by using several sophisticated techniques of structure characterization (12,13), supported now by theoretical calculations (14).…”

The thermal stability of the C 60 photopolymer, the C 60 ozopolymer, and photochlorinated C 60 was studied by thermogravimetric analysis (TGA) ultraviolet-visible (UV-vis) and TGAdifferential thermal analysis techniques up to 950 • C in comparison to graphite and pure C 60 . The ozopolymer was found to be the least stable material followed by C 60 Cl x . The resulting residual carbonaceous matter formed by the decomposition of the photopolymer and the ozopolymer has been studied by Fourier transform-infrared (F TIR) spectroscopy and has been found to be completely comparable to carbon black. The thermal decomposition of the C 60 photopolymer prepared in solution yields negligible amounts of C 60 . The main product is carbon black. 55

Halogenated fullerenes have been subjects of intensive investigations since the discovery of fullerene, because of their possible further derivatization. This paper reviews the synthesis and molecular structures of fullerene bromides and chlorides, covering earlier work in this field and progress in synthetic methods developed by the authors. The use of inorganic chlorides and oxychlorides for the chlorination of fullerenes allowed the preparation of new compounds that have been fully characterized by single-crystal X-ray diffraction and IR spectroscopy and confirmed by theoretical calcula-

Fullerene Black (FB) and Extracted Fullerene Black (EFB) were used in modified screen‐printed electrodes producing electrochemical transducers (FB‐SPEs and EFB‐SPEs). A complete electrochemical study was performed and the best results are obtained working with FB‐SPEs, especially in terms of: 1. improved electron‐transfer kinetic mechanisms and 2. sensitivity and selectivity toward Acetaminophen (Ac) and Guanine (G). These latter represent two important electro‐active targets to quantify in medicine field application, because: Ac is a preferred alternative (as analgesic‐antipyretic agent) to aspirin, particularly for patients who cannot tolerate aspirin; the oxidation signal of G is useful for the fabrication of emerging analytical tools, such as DNA chipsand user‐friendly diagnostic devices. Ac and G are quantify by using FB‐SPEs electrochemical devices, with an extended linearity (1–300 μM for Ac; 0.1–300 μM for G), an excellent sensitivity (2.82 μA μM−1 cm−2 in the case of Ac; and 0.183 μA μM−1 cm−2 in the case of G), a low detection limit (0.01 μM for Ac; 0.005 μM for G), a very good reproducibility (both: intra‐; inter‐electrodes reproducibility RSD % ranging from 0.3–0.5 for Ac; and 0.50–0.85 for G) and a very fast response time (6 s for Ac; 5 s in the case of G). In addition, high selectivity is obtained at FB‐SPEs, meaning that the FB‐SPEs electrochemical transducers are suitable to simultaneously quantify Ac and G in real samples, having several different (highly concentrated) interference.
