and 1-butyl-4-methylpyridinium salts (∼115 °C). The salts were thermally stable up to 180 °C [decomposition of an oligo(ethylene glycol) chain] and contained variable amounts of water. The flexible oligo(ethylene glycol) chains contributed to the waxy state of salts. The solubility of the salts was determined for 76 solvents that are commonly used in organic chemistry. Generally, the solubility increased
A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A− form) in non-aqueous media. The anion loading of the AER (OH− form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A− form) method in organic solvents was

identifying ion interactions leading to higher melting points of the halide salts with respect to the [PF6]–salts. The changes in hydrogen bonding, C–H⋅⋅⋅π, and van der Waals interactions have been analyzed with respect to anion, functional groups, and the symmetry of the cation to establish interdependence with the compound’s physicochemical properties. It has been observed that the cation–anion interactions
The synthesis and characterization of a new member of the pillar[5]arene family carrying a paramagnetic side-arm based on the 2,2,6,6-tetramethylpiperidine N-oxide (TEMPO) moiety has been achieved by the Huisgen-type CuAAC reaction. The possibility of exploiting the proposed pillar[5]arene as a host in paramagnetic rotaxane-like structures was tested in the presence of charged guests and confirmed
