Self-assembly of subnanometer-diameter single-wall MoS2 nanotubes

We report on the synthesis, structure, and self-assembly of single-wall sub nanometer-diameter molybdenum disulfide tubes, The nanotubes are up to hund reds of micrometers Long and display diverse self-assembly properties on di fferent Length scales, ranging from twisted bundles to regularly shaped "fu rry" forms. The bundles, which contain interstitial iodine, can be readily disassembled into individual 'molybdenum disulfide nanotubes. The synthesis was performed using a novel type of catalyzed transport reaction including C-60 as a growth promoter.
