Metal-carbon bond metal-organic frameworks with permanent porosity

The main coordinate bonds used in constructing metal -organic frameworks (MOFs) are metal-nitrogen (M-N), metal-oxygen (M-O), and metal-sulfur (M-S) bonds, but the metal-carbon (M-C) bonds are yet to be used as the linkages. Here, two iso-reticular crystalline MOFs connected by M-C bonds are reported. Combining various characterization methods, the structures of the two M-C bond MOFs (MC-MOFs) were investigated. MC-MOFs both exhibit three-dimensional (3D) rigid skeletons with uniform one-dimensional (1D) channels, and the specific areas are 640 and 960 m(2) g(-1) semiconductive, presenting potentials as photoelectric materials or photocatalysts. , respectively. More interestingly, the two MC-MOFs are
