Two-Dimensional Conductive Metal–Organic Frameworks Based on Truxene

Two dimensional conductive metal–organic frameworks (2D cMOFs) have been widely applied as electrocatalysts, electronic devices, and sensors. In addition, their intrinsic electronic properties could be efficiently tuned via varying the conjugated linkers. Herein, we report a novel 2D cMOF based on c...

Description
Summary:Two dimensional conductive metal–organic frameworks (2D cMOFs) have been widely applied as electrocatalysts, electronic devices, and sensors. In addition, 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 ions via the energy economical interfacial reaction. This 2D cMOF was obtained as a brilliant black powder and showed a bulk electrical conductivity of 3.5 × 10–3 S cm–1 at 30 °C. Additionally, the cMOF-modified glassy carbon electrode could act as an electrochemical sensor for sensing paraquat with a limit of detection at 4.1 × 10–8 M (S/N = 3). The accession of truxene-Cu to the cMOF family would shed new light on the impact of the organic conjugated linker and broaden the scope of cMOFs’ applications.
