Two-Dimensional Conductive Metal-Organic Frameworks Based on Truxene

Two dimensional conductive metal-organic frameworks (2D cMOFs) have been widely applied as electro-catalysts, electronic devices and sensors. And their intrinsic electronic properties could be efficiently tuned via varying the conjugated linkers. Herein, we report a novel 2D cMOF based on complexation of 2, 3, 7, 8, 12, 13-hexahydroxyl truxene and copper ion via the energy economical interfacial reaction. This 2D cMOF was obtained as a brilliant black powder and showed bulk electrical conductivity of 3.58ｘ10-3 S cm-1 at 30 oC. Additionally, the cMOF modified glassy carbon electrode could act as electrochemical sensor towards paraquat with LOD at 4.1ｘ10-8 M (S/N = 3). The accession of truxene-Cu to the cMOF family would shed new light on the impact of organic conjugated linker, and broaden the scope of cMOFs’ applications.
