Abstract
C-60 biphenyl derivatives were synthesized, and their structures were chara cterized by FT-LR,H-1 NMR and FD-MS. It was found that the products are mix ture of C-60(biphenyl)(x) and C-60(biphenyl)(x)C-60 x = 3-7. The molecular images of C-60(biphenyl)(x) and C-60(biphenyl)(x)C-60 were directly observe d by scanning tunneling microscope. The Z-scan technique was used to measur e the third-order optical nonlinearity of the C-60 derivatives; chi((3)) = 2.3 X 10(-5) esu. (C) 2000 Elsevier Science Ltd. All rights reserved.
