Synthesis, Structure, and Characterization of a New Metal‐Organic Framework containing Meso‐Helices

Abstract

The new metal‐organic framework [Cd(bqdc)(phen)]n (1) (bqdc = 2, 2′‐biquinoline‐4, 4′‐dicarboxylate, phen = 1, 10‐phenanthroline) was hydrothermally synthesized by hetero‐ring carboxylate ligand and N‐containing auxiliary ligand. The structure of 1 was determined by single‐crystal X‐ray diffraction analysis and further characterized by elemental analyses, IR spectroscopy, X‐ray powder diffraction, and TG analysis. Single‐crystal X‐ray structural analysis shows that complex 1 is an infinite two‐dimensional framework containing aesthetic meso‐helix. These two‐dimensional coordination networks are interconnected through aromatic π–π stacking and C–H···O hydrogen bonding interactions to afford a 6‐connected (412.63) three‐dimensional supramolecular architecture. Furthermore, the photoluminescent property of complex 1 was studied.

Design and synthesis of coordination polymers with chelated units and their application in nanomaterials science

“…MOF with [CdL(phen)] n unit is hydrothermally synthesized using heterocyclic 2,2 0 -biquinoline-4,4 0 -dicarboxylate ligand (L) and N-containing ancillary ligand. 156 The complex is innite 2D framework networks containing aesthetic meso-helix, which are linked with formation of 6-connected 3D supramolecular architecture through aromatic p-p stacking and C-H/O-Hbonds interactions.…”

Synthesis and electrocatalytic performance of phosphotungstic acid-modified Ag@Pt/MWCNTs catalysts for oxygen reduction reaction

“…The cage structure has some pores that allow oxygen-containing materials to move freely and improve the contact area among reactants [27]. Thus, Keggin-structured HPW has attracted many researchers' attention due to its unique physicochemical characteristics [28][29][30][31][32]. For instance, Xiang et al prepared a composite membrane combination HPW with Nafion, and the maximum power density of the composite membrane increased by 26 % over the cell performance of pristine Nafion under the same conditions.…”

Prussian Blue Analogue Mesoframes for Enhanced Aqueous Sodium-ion Storage

“…Besides the great success achieved on the molecular/atomic scale, the structure design on a mesoscale (10~1000 nm) has recently been recognized as a promising choice [16][17][18][19]. By downsizing of a bulk crystal, the volume ratio of the surface units to the bulk units can be increased significantly, leading to a coupling effect from the bulk structure and the surface units [17,20,21]. For instance, the meso-sized coordination polymers can accommodate guest molecules still, but their phase-change type would be changed owing to the suppressing effect of the surface energy [14,[22][23][24].…”
