STUDIES ON CHARACTERISTICS AND CONDUCTIVI TY OF 1,3,6,11,13,18,28,31-OCTABROMOFULLERENE-C-60 LB FILMS

The molecular behavior of the substituted fullerene 1, 3, 6, 11, 13, 1 8, 28, 31-octabromofullerene (C60Br8) on the air-water interface is de scribed, It is shown that the high-quality LB films of the compound ca n be constructed onto a variety of solid substrates, An ESR observatio n exhibits a signal with g = 2.002 4 and Delta H = 2 X 10(-4) T due to C-60(+). Electronic absorption spectra show several strong bands from 224 to 570 nm, the maximum band is at the position of 570 nm, The ele ctrical conductivity studies suggest that the conductivity is dependen t on the layer numbers of LB film and temperature, The thermal activat ion energy is 0.285 eV.
