“…There are several other reports where ILs have been employed as a solvent to dissolve single-walled carbon nanotubes, 32 fullerenes, 33 and metallomesogens. 34 High performance liquid chromatography (HPLC) Ionic liquids have been incorporated in two different ways for improving chromatographic separations using HPLC. These include using the ILs as additives to the mobile phase or immobilizing them to the stationary phase.…”

Ionic liquids (ILs) have drawn considerable interest for their use in various analytical techniques including chromatography, extractions, and mass spectrometry. This is largely due to the flexibility in tuning the physicochemical properties of ILs. There has been a significant increase in the number of publications over the last decade in which ILs have been employed as a chromatographic stationary phase, extraction solvent, or sorbent material in various preconcentration techniques. This review article highlights the recent advancements in the use of ILs in separation science including gas chromatography, high-performance liquid chromatography, capillary electrophoresis, extraction and microextraction techniques as well as mass spectrometry.

“…To evaluate the thermal stability of DFP, thermogravimetric (TG) analysis was carried out on a LCT-2 TGA analysis instrument (Beijing Optical Instrument Factory, Beijing, China). 25,26 A 25 mg sample was heated from 40 C to 700 C at a rate of 10 C min À1 under a dynamic nitrogen atmosphere. The result revealed that both of the DFPs had a similar initial decomposition temperature, which began to decompose slightly at 380 C. However, with temperature increases, DFP-8 began to show a more dramatic weight loss, e.g., when the decomposition of DFP reached 20% of the original quality, the temperature of DFP-8 was much lower than that of DFP-15 by 30 C (Fig.…”

In this work, a new polycyclic phenyl grafted polysiloxane called DFP-15 (15.1% 3,4-2(trifluoromethyl phenyl)-2,5-diphenyl phenyl) was synthesized by the Diels-Alder reaction of tetraphenyl cyclopentadienone monomer containing trifluoromethyl groups with methyl vinyl polysiloxanes composed of 18% methyl vinyl and 82% dimethyl groups. A second chemical called DFP-8 was also prepared for comparison purposes. The thermal stability was evaluated by thermogravimetric analysis, and the results revealed that both of the DFPs had similar thermal stability, and they began to decompose slightly at 380 C. Subsequently, the copolymers were coated on fused silica capillary columns by static coating and used as a stationary phase and were characterized. The column efficiencies of the DFP-15 and DFP-8 columns were 3960 plates per m (k ¼ 1.90, naphthalene) and 3740 plates per m (k ¼ 1.74, naphthalene), respectively. The excellent film-forming ability in the inner surface of the fused silica capillary columns was proven by the analysis of Grob reagent. Furthermore, the selectivity of the novel stationary phases for analytes, including substituted benzene isomers and polycyclic aromatic hydrocarbons, was evaluated. This work suggests that both of the stationary phases have great potential for further development and application.

“…was obtained from Polymicro (Phoenix, AZ, USA). The GC separation column was prepared according to the procedures published previously [30]. Briefly, a solution of equal amount of 1-benzyl-3-methylimidazolium trifluromethanesulfonate (BeMIM-TfO) (1%, w/v) and polycatenar oxazoline copper(II) complex [Cu(S-C 12 ) 2 ] (1%, w/v) in dichloromethane was introduced into the column under constant pressure of 0.101 MPa.…”
