A mesoporous metal-organic framework based on a shape-persistent macrocycle.
نویسندگان
چکیده
A mesoporous Zn-based metal-organic framework (MOF) was prepared from a shape-persistent phenylene ethynylene macrocycle functionalized with three -COOH groups. The rigid ligand has a ∼9 Å wide central cavity which serves as a predesigned pore. The macrocycles [π···π] stack into pairs, with their carboxylate groups connected via three Zn3O14C6H2 clusters. The resulting MOF has a void volume of 86%.

Mesoporous 2D covalent organic frameworks based on shape-persistent arylene-ethynylene macrocycles† †Electronic supplementary information (ESI) available: Experimental procedures, TGA, FT-IR, PXRD and NMR spectra of compounds. See DOI: 10.1039/c5sc00894h
Macrocycle-to-framework strategy was explored to prepare covalent organic frameworks (COFs) using shape-persistent macrocycles as multitopic building blocks. We demonstrate well-ordered mesoporous 2D COFs (AEM–COF-1 and AEM–COF-2) can be constructed from tritopic arylene-ethynylene macrocycles, which determine the topology and modulate the porosity of the materials. According to PXRD analysis a...
متن کاملHighly Effective Dual Transition Metal Macrocycle Based Electrocatalyst with Macro-/Mesoporous Structures for Oxygen Reduction Reaction
Metal macrocycle based non-noble metal electrocatalysts (NNMEs) with highly efficient oxygen reduction reaction (ORR) activity, good stability, and excellent resistance to the methanol cross-over effect have been regarded as one of the most important alternatives for Pt or Pt based alloys, which are widely used in fuel cells. However, the expensive price of most metal macrocycles hinder further...
متن کاملMetal-organic framework materials as nano photocatalyst
Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...
