Study of the Ozonolysis Rate Constants' Dependence from the Degree of Oxidation of C₆₀Fullerene and Trans‐1,4‐Polychloroprene

Reaction Probability and Infrared Detection of the Primary Ozonide in Collisions of O3 with Surface-Bound C60

“…40 The other two IR-active modes, at 577 and 527 cm −1 , 40 are outside of the detection range of the MCT detector (4000−750 cm −1 ). The smaller peaks present in this spectrum are due to combination, 13 C isotopes, higher-order IR, and Raman modes of the C 60 layer adjacent to the gold surface that become IR-active due to disruption of the molecular symmetry of the adsorbate. 40−42 Following initial characterization, the C 60 -covered Au surface was exposed to a continuous source of ozone, and changes to the film were tracked with RAIRS.…”

“…For example, recent research indicates that ozone readily oxidizes C 60 in various solvents, including water. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] 26 However, definitive spectroscopic characterization of the PO has yet to be reported. Similar to C 60 , the PO of alkenes and other polycyclic aromatic hydrocarbons is known to be extremely short-lived.…”

“…In contrast to experiments at the gas–surface interface, condensed-phase reactions between C 60 and ozone have been explored by a number of groups. For example, recent research indicates that ozone readily oxidizes C 60 in various solvents, including water. − In 2000, Heymann et al detected and isolated an unstable intermediate that appeared during the ozonation of C 60 /toluene solutions. These researchers employed liquid chromatographic methods to help identify the intermediate as C 60 O 3 , the primary ozonide (PO) of C 60 .…”
