DescriptionAs the power source of modern society, petroleum and related products are playing important role in chemistry and environment. Basically, light aromatics and C6 paraffines are crucial parts of petrochemical industry. Effective and economic separation of those hydrocarbons from the mixture of isomers or homologous series remains a difficult problem for oil company. Metal organic frameworks (MOFs) or coordination polymers (CPs) would be the potential candidate to this problem due to the porosity and stability. In this work, a novel flexible dual-ligand MOF, Zn-atz-bpda was synthesized and it exhibits very interesting adsorption behavior toward hydrocarbons. The framework can be very easily made by solvothermal reaction of aminotriazole ligand and dicarboxylate ligand with zinc ions. Introducing of triazole ligands enhance the stability and certainty of the MOF. Single crystal XRD unveiled the pillared-layered structure and the distorted aromatic rings might be crucial for the flexibility of Zn-atz-bpda. The structure of Zn-atz-bpda remained robust in organic solvent and acidic solutions and it displayed interesting adsorption properties to aromatic and C6 hydrocarbons. The mechanism and flexibility of it might be a new strategy for designing MOFs with higher performance.
