PHOTOTRANSFORMED C-60 POWDER AND FILM SYNTHESIZED IN TOLUENE, BENZENEAND CARBON-DISULFIDE SOLVENTS

C-60 dissolved in toluene, benzene and carbon disulfide respectively, yielded a brown precipitate upon exposure to ultraviolet radiation. A thin him was deposited on a silicon substrate when dipped in each of t he solutions. Further examination of this deposit revealed: (1) the su bstance to be amorphous by TEM observation; (2) No oxygen was detected by Auger electron spectroscopy; (3) Absorption peaks produced by FT-I R differed from those of pristine C-60, solid-state photopolymerized C -60 and high-pressure polymerized C-60; (4) The same substance was obt ained for each of the three solvents; (5) The substance obtained is pr esumably a new photopolymerized C-60 solid.
