First-principles studies of electrophilic molecules on the carbon nanotubes

Park S., Kong K-J, So H-M, Buh G-H, Lee J-O, Chang H., Korea Research Institute of Chemical Technology, KR

Recently we have reported that some electrophilic molecules, such as 2,4,6-triphenylpyrylium tetrafluoroborate (2,4,6-TPPT) and 1,3-benzodithiolylium tetrafluoroborate (1,3-BDYT), preferentially interact with metallic single-walled carbon nanotubes (SWNTs). It resulted in selective suppression of conductance in metallic carbon [...]
