Abstract

Metal-organic nanotubes (MONTs) are tunable porous 1D materials that are envisioned to be complementary to carbon nanotubes for anisotropic applications. To date, characterization of MONTs relies on single crystal X-ray diffraction (SCXRD) to determine structure and composition. This requires crystals on the micrometer regime, effectively rendering bulk 3D materials. By tracking the growth of a MONT as a function of time with liquid-cell transmission electron microscopy (LCTEM), TEM, and SCXRD, it was possible to ascertain that the material in the bulk phase matches the nanomaterial in terms of molecular structure. This result allowed for the first measurements of finite bundles of MONTs on the nanometer scale. By employing in situ LCTEM, a time course of the formation of small bundles of MONTs could be acquired which provided mechanistic information on MONT formation which is of utility in reaction optimization and applications development.
