“…In supramolecules, the individual building blocks may be self‐assembled by covalent bonds, coordinate bonds and weak interactions like hydrogen bonds, π⋅⋅⋅π stacking interactions, halogen bonds, carbonyl⋅⋅⋅carbonyl interaction, etc . Coordination polymers, including metal organic frameworks, belong to a class of supramolecules in which the nodes are metal complexes and the linkers are bridging organic or inorganic ligands . Regarding inorganic bridging ligands, azide is a nice linker because it can coordinate to metal ions in various modes such as μ 1,1 ‐ (end‐on; commonly expressed as EO), μ 1,3 ‐ (end‐to‐end; commonly expressed as EE), μ 1,1,1 ‐, μ 1,1,3 ‐, μ 1,1,1,1 ‐, and μ 1,1,3,3 ‐ ,.…”
