Negative stain TEM characterization of Zn8R4 arrays. (a) Single Class I nanotube with tubular (bottom) and frayed (top) segments. (b and c) 2D reconstructions of tubular (b) and frayed (c) regions of a single nanotube. The crystallographically characterized 2D arrangement of Zn8R4 molecules are superimposed onto the TEM reconstructions. The slight mismatch between the crystallographic model and TEM reconstruction in (b) is likely due to the curved nature of the 2D arrays which is, to some extent, accounted for by the curvature of the tubes.
