Polycatenation tuned microporosity of two metal–tris(4′-carboxybiphenyl)amine frameworks with multilayer structures†
Abstract
By employing a nanosized tris(4′-carboxybiphenyl)amine ligand to assemble with Zn2+ ions, a novel trilayer network (FIR-37) and an unprecedented 2D → 3D microporous polycatenation framework (FIR-38) based on unusual tetralayers have been synthesized and structurally characterized. FIR-38 shows permanent porosity with a Langmuir surface area of 1408.4 m2 g−1.
