[Abstract]:Metal-Organic frameworks (MOFs) is a new porous organic-inorganic hybrid material with large specific surface area, high porosity, easy adjustment of pore size and functional interface. It has potential applications in many fields, such as gas storage, adsorption and separation, sensing, catalysis and life science. In this paper, a series of organic ligands with carbazole as parent have been synthesized, and their supramolecular self-assembly chemistry with transition metal ions has been studied. Thirteen unreported coordination compounds have been obtained by solvent-diffusion to solvothermal assembly. Their structures were characterized by IR X-ray single crystal diffraction, powder diffraction and elemental analysis. The physical and chemical properties of some compounds were studied. One, 12 carbazole-bridged organic ligands, L1-L12, which were substituted by ether bonds, were synthesized by solvent-diffusion and solvothermal method to obtain 8 stable coordination compounds. Secondly, several novel electrode materials were prepared by using compound 1. By adjusting the assembly conditions, the micronanocrystallization of the Co-III-MOF was realized, and the uniform morphology of nano-scale Co (鈪，
