## Description

- description: Bis(diimino)metal complex nanosheets composed of metal ions and hexaaminobenzene
    ligands (MHABs) are fascinating two-dimensional materials which have been gaining
    significant attention as electrode materials and electrocatalysts owing to their
    electrical conductivities, redox properties, and porous structures obtained by
    the π-conjugated system and regular metal complex arrangement. Although electrochemical
    oxidation enables the simple and direct formation of MHABs on electrodes within
    a couple of minutes only, the obtained MHABs are relatively rough and of low crystallinity.
    This study investigated the effects of the applied potential during the synthesis,
    the type of base, and the concentrations of bases and building blocks on the synthesis
    of NiHAB nanosheets. Optical microscopy (OM), atomic force microscopy (AFM), Raman
    spectroscopy, X-ray photoelectron spectroscopy (XPS), and grazing-incidence X-ray
    scattering (GIXS) results revealed that a low oxidation potential, high concentration
    of the ammonia solution, and low concentration of the building blocks in the reaction
    solution provided a nanometre-thick NiHAB layer. Under the optimal reaction conditions,
    NiHAB nanosheets were successfully synthesized in a face-on orientation manner
    on gold electrodes using electrochemical oxidation methods. Furthermore, the anisotropic
    electrochemical synthesis of CuHAB was achieved under the optimised conditions.
    The mechanism of the MHAB growth process with an anisotropic orientation and nanometre
    thickness was proposed and attributed to the flat adsorption of π-conjugated oligomers
    composed of bis(diamino)metal moieties in a solution onto an electrode surface
    and the electrochemical oxidation and deprotonation of the adsorbates on the electrode.
