Abstract

Since the isolation of graphene, many 2D materials either inorganic or organic have been studiedaspromising candidates for applications inelectronics, catalysis and others. Some of these materials are monolayers comprising a single element or materials with different atoms alternating in the same layer, or even layers containing molecules coordinated to metal ions, the later also called 2D Metal-Organic-Framework (MOFs) nanosheets.1An increasing recent interest have been focus on 2D MOF nanosheets, due to their unique properties originated from their ultrathin thickness and large surface area with highly accessible active sites.1The preparation of 2D MOF nanosheets can be performed either by a top-down exfoliation method, where the weak interlayer interactions can be broken into single-or few-layered MOF nanosheets, or by a bottom upapproach following a direct synthesis from metal ions and ligands, restricting the growth in one of the directions.1In this work we present a new 2D MOF nanosheet based on a curcuminoid ligand (CCMoid)and zinc ions. In mygroup, we design CCMoidmolecules2, organic conjugated species, which possess a central β-diketone moietyand twoterminal aromatic groups,which can possessfunctional groupsto further coordinate. We specialized on the modification of curcuminoidligands for several objectives, suchas single-molecule electronic studies and use of SAMs of such CCMoidson devices.3,4Here, Figure 1 shows the structure of the new 3-pyCCMZn(NO3)2D-MOF, where the layeredstructure is depicted bydifferent colors. Ourstudies show that we are capable of generating new homogenous 2-micron crystalline samples byredissolvingthe crystals. Our goals are the organization of such structures on different substrates (electrodes) and the study of their electronic features.
