“…[16][17][18] Extensive research has focused on spectroscopic, especially ESR, studies of fullerene anions or adduct radicals generated by various techniques. [19][20][21][22][23] In the present study we show, based on the close reexamination of our recently reported ESR spectra, [13][14][15] the formation and characterization of NaC60 and HC60 in NaY nanocavities.…”

“…Although the g 0 -values from Figure 1 are typical values for organic radicals, they are significantly larger than those (2.0006, 19 2.001, 20 1.998 21 ) of C 60 − in solutions. The large g 0 -values are considered to arise from the polar environment.…”

His research interests include reactive cation and superacid chemistry with inert carborane counterions, ionic liquids, bioinorganic chemistry, spin-coupling phenomena, fullerene chemistry, and new carbon-or porphyrin-based materials. He is a Sloan Fellow, a Dreyfus Teacher−Scholar Awardee, and a Guggenheim Fellow. Robert Bolskar received his B.S. degree in Chemistry from Carroll College in Waukesha, WI, in 1992. He earned his Ph.D. degree at the University of Southern California in Los Angeles under the direction of Christopher Reed in 1997, investigating the synthetic redox chemistry of fullerene anions and cations. In 1998 he moved to the University of California, Riverside, as Managing Research Associate. He is currently Senior Chemist at TDA Research in Wheat Ridge, CO. His research interests include the chemistry and physics of fullerene compounds, supramolecular chemistry, strongly oxidizing systems, and electrophilic cations.

“…Many reports concerning the characterization of the UV-vis and near-IR absorption spectra of fullerene and fulleride ions have been presented. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] According to these reports, the possibility of the Jahn-Teller distortion from Ih symmetry of C60 -can not be completely excluded; the shape of C60 -is nevertheless supposed to be almost spherical and the size to be similar to that of C60. 3,18,24,29,30,33 Some data of diffusion coefficients of C60 (DC60s), determined by electrochemical methods in similar experimental environments, are listed in Table 1.…”

Diffusion Coefficients of C60 and C60– in Benzonitrile and Dichloromethane Solutions Containing Tetrabutylammonium Perchlorate, Measured by Potential-step Chronoamperometry

et al. 2006

The diffusion coefficients of C60 in dichloromethane and benzonitrile solutions containing 0.1 M tetrabutylammonium perchlorate were determined by single potential-step chronoamperometry at small disk electrodes. The diffusion coefficients of C60 were obtained by curve fitting of the chronoamperograms to a theoretical equation by Shoup and Szabo. The values were (1.4 ± 0.3)× 10 -9 and (4.1 ± 0.3)× 10 -10 m 2 s -1 , respectively (the errors are 95% confidence limits). The diffusion coefficients of C60 -in these solutions were measured by double potential-step chronoamperometry. The ratios of the diffusion coefficients of C60 to those of C60 -were obtained from theoretical curves of the ratios of the current at the second potential step to the current at the first one. The values of the ratios were 1.2 ± 0.2 and 1.0 ± 0.3, respectively.
