摘要: Ligands with flexible conformations add to the structural diversity of metal–organic frameworks but, at same time, pose a challenge design and prediction. Representative examples include Zr-tetracarboxylate-based MOFs, which afford assorted structures for wide range applications, but also complicate control. Herein, we systematically studied formation mechanism series (4,8)-connected MOFs by altering substituents on different positions organic linkers. Different ligand rotamers give rise three types flu, scu, csq topologies. A combination experiment molecular simulation indicate that steric hindrance dictates resulting MOF structures. Additionally, controllable was successfully implemented linkers effects specific positions.
