Abstract

A chain nickel coordination polymer with the chemical formula [Ni(iptp) 2 (SDA) 2 (H 2 O) 2 ] n , the central ion Ni(II) is in a six-coordinated coordination environment, which coordinates with two N atoms from two different iptp respectively, and coordinates with two different H 2 Two O atoms of SDA coordinate with O atoms on two water molecules to form NiO 4 N 2 octahedral configuration. The synthetic method is as follows: weigh 4-(imidazol-1-yl) phenyl-4,2':6',4 "-terpyridine, 4,4'-stilbene dicarboxylic acid and Add nickel chloride into the solvent, stir and dissolve completely; adjust the pH value to 9-11; put it into the reactor to seal, put in the iron sleeve, tighten it, and react at a constant temperature of 160°C until the end; take out the reactor to cool, and filter , the filtrate was naturally volatilized at room temperature to obtain green blocky crystals.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a chain nickel coordination polymer [Ni(iptp)2(SDA)2(H2O)2]n and a synthesis method thereof. Background technique [0002] At present, in terms of the synthesis of complexes, the synthesis and properties of complexes constructed with carboxyl-containing organic compounds as the main ligand are the most widely studied. Carboxyl-containing organic ligands have the characteristics of diverse coordination modes, and are the most commonly used organic ligands for the synthesis of complexes. Furthermore, carboxyl-containing organics are excellent ligands for the design and synthesis of new materials and functional supramolecular structures due to their potential to form hydrogen bond donors and acceptors. Compared with general carboxyl-containing organic ligands, rigid aromatic polycarboxylic acid ligands have a fixed skeleton structure, are not prone to steric deformation, and have a control...
