Two Dimensional Electrically Conductive Metal-Organic Frameworks

Metal-organic frameworks( MOFs) are a class of crystalline porous materials formed by self-assembly of metal ions or clusters and organic ligands through coordination bonds. Due to the high porosity and functional designability. MOFs have found wide applications of which make them widely used in various fields. However. most traditional MOFs have poor conductivity. which severely restricts their development in electrical related fields. In recent years. electrically conductive MOFs. especially two dimensional electrically conductive MOFs (2D ECMOFs). have attracted a great deal of research attention due to their semiconducting or metallic properties closely-related to their unique pi-pi stacking and pi-d conjugation structures. which have great application potentials in electrical and energy related fields such as sensors. electronics. electrocatalysts. batteries. and supercapacitors. In this review. the recent progress in conducting mechanisms. structures. synthesis strategies and applications of 2D ECMOFs are summarized and highlighted. Furthermore. future challenges and opportunities based on the current research status are prospected.
