The anion exchange reaction of bis(isoquinoline) ionic liquids: self-assembly, crystal structures and thermal properties of ten novel d10 metal (Cu, Ag) halide/thiocyanate supramolecular polymers

(1‐Butyl‐4‐methyl‐pyridinium)[Cu(SCN)2]: A Coordination Polymer and Ionic Liquid

“…No μ 1,1 ‐coordination of the thiocyanate sulfur atom is found in (C 4 C 1 py)[Cu(SCN) 2 ], but exclusively μ 1,3 ‐coordination. Such a coordination mode has been first proposed on the basis of IR and Raman spectroscopic investigations,15 and has been confirmed later by X‐ray structure analysis in other compounds with non‐coordinating counterions 4. 5…”

“…Great synthetic efforts are spent to increase the solubility 3. Problems with solubility are even more severe in the case of coordination polymers with strong bridging ligands such as thiocyanate (SCN − ) 4. 5 The difficulties in processing such a one‐dimensional coordination polymer, which suffer frequently from low solubility, are an obstacle to the fabrication of devices and therefore limit the applicability of these compounds, despite their interesting properties.…”

“…Usually, extra capping ligands are used to block the additional coordination sites at the metal cation and to direct the synthesis towards the desired coordination mode and nuclearity 9–14. However, one‐dimensional homoleptic thiocyanato complexes could be obtained by using non‐coordinating counterions 4. 5 The resulting polymer is able to show luminescence and might also be a one‐dimensional semiconductor, because the local oxidation of copper(I) to copper(II) can be thought of as creating a hole, which might then migrate along the chain through a hopping mechanism.…”

Synthesis, structures and properties of two novel supramolecular polymers of Cu(I) with 1,1′-Bis(isoquinoline)-1,4-Phenyldimethylenyl

“…In this work, we have prepared BIQPM 2+ as molecular-based organized systems (MOS), for the generation of supramolecular self assembly. Compounds 1 and 2 reveal that different frameworks can be synthesized by using the same organic templates, on the other hand similar topological structures can be synthesized by using the different organic template, such as the compounds {(BIQHX) 2 [Cu 4 I 8 ]· DMF}) and {(BIQBT)[Cu 2 (SCN) 4 ]} n (BIQHX = 1,6-bisisoquinolinehexane, BIQBT = 1,4-bisisoquinolinebutane) [19]. From the above compounds we can see that the halide/thiocyanate groups have an important cooperative impact on the cation template effect.…”

A supramolecular metal-organic framework derived from bismuth iodide and 4,4′-bipyridinium derivative: Synthesis, structure and efficient adsorption of dyes

“…Although a host of applications that utilize the MOFs for the degradation of organic dyes have been explored, work about rapid dye adsorption of MOFs has been rarely reported [5b]. Supramolecular complexes are materials formed by monomeric components which are connected through noncovalent interactions (e.g., van der Waals, hydrogen bonding and coordinative interactions) [11][12]. Those structures contained channels based on the van der Waals interactions are still rare [13].…”
