Unique ZnII coordination entanglement networks with a flexible fluorinated bis-pyridinecarboxamide tecton and benzenedicarboxylates

Abstract

Entangled nets in coordination compounds with both self-penetrating and interpenetrating structural features have been first constructed by using a flexible bis-pyridinecarboxamide and isophthalate or 5-methylisophthalate. Distinct entangled systems showing both 3-fold interpenetration and polyrotaxane can also be obtained by altering the 5-substituents of isophthalate.

Ultrasound Assisted NucleophilicCyclization of Tetrafluoroterephthalonitrile: An Efficient Way to Fluorine‐Containing Heterocycles

“…The introduction of fluorine atoms into MOFs can adjust the coordination arrays, the host organizations and the cavities, exhibiting high density gas uptake and extraordinary hysteretic sorption of H 2 abilities . We also have reported some novel MOFs with 2D and 3D networks using tetrafluoroterephthalic acid, a derivative of a , as the ligand …”

Bismuth(III) Complexes Based on Bis(triazol) Ligands: Effect of Fluorine Substitution on the Structure and Catalysis for the Polymerization of Glycolide

“…[13] Detailed studies of the effect of fluorinated and nonfluorinated ligands on the structures and properties of metal-organic crystalline materials were performed. [14][15][16][17] To further extend this research, two flexible bis(triazol) derivatives were chosen in this work (see Scheme 1), namely nonfluorinated 1,4-bis[ (1,2,4- www.zaac.wiley-vch.de ARTICLE more, comparative catalytic activities of both complexes in the bulk ROP of glycolide are described.…”

ChemInform Abstract: Ultrasound Assisted Nucleophilic Cyclization of Tetrafluoroterephthalonitrile: An Efficient Way to Fluorine‐Containing Heterocycles.

“…[2] Tetrafluoroterephthalonitrile a is a very important organic intermediate. [5][6][7][8] In continuation of work on developing new MOFs with fluorine-containing organic ligands, recently, we focused on the synthesis of ligand c, which could be obtained via condensation reaction between tetrafluoroterephthalonitrile and ethylenediamine under certain conditions. For example, it can be hydrolyzed and then reduced to form 2,3,5,6-tetrafluoro-1,4benzenedimethanol, which is the key intermediate for the preparation of pesticide tefluthrin.…”
