摘要

摘要:实验旨在阐明分子氧在富勒烯光解中的作用。在不同的实验条件下,研究了氧-富勒烯加合物在不同溶剂的富勒烯溶液和由这些溶液蒸发形成的微晶中的形成,以及它们的光解作用。结果证实,在这些体系中,氧在光解过程中的作用是矛盾的,并且高度依赖于富勒烯辐照发生的条件(光解辐射的波长和强度、溶剂分子的性质、溶剂-富勒烯-氧体系中是否存在附加分子等)。

The Role of the Oxygen Molecule in the Photolysis of Fullerenes
Abstract Experiments designed to clarify the role of molecular oxygen in the photolysis of fullerene are described. The formation of oxygen-fullerene adducts, both in fullerene solutions in various solvents and in micro-crystallites formed by evaporating these solutions, and their photolysis was studied under various experimental conditions. The results confirm that the role of oxygen in the photolysis process in these systems is ambivalent and highly dependent on the conditions under which the irradiation of the fullerenes occurs (wavelength and intensity of the photolyzing radiation, character of the solvent molecules, presence of additional molecules in the solvent-fullerene-oxygen system, etc.).
