摘要：

[GRAPHICS] Tetrahedrally shaped nanoscale molecules 18-20 were synthesized from the corresponding tetraiodide by a series of Sonogashira coupling reactions. Three of the sulfur-containing termini are intended for eventual binding to a gold-coated conventional AFM tip, while the fourth terminus scans the sample. AFM images of 19 demonstrate that the molecule is sufficiently large and rigid to be imaged by a conventional AFM tip.
