1-Alkenyl-3-methylimidazolium trifluoromethanesulfonate ionic liquids: Novel and low-viscosity ionic liquid electrolytes for dye-sensitized solar cells

Dye-sensitized Solar Cells (DSCs) based on ruthenium complex N719 as sensitizer have received much attention due to their affordability and high efficiency. However, their best performance is only achieved when using volatile organic solvents as electrolyte solutions, which are unstable under prolonged thermal stress. Thus, we developed a new series of 1-alkenyl-3-methylimidazolium trifluoromethanesulfonate ionic liquids used as robust DSC electrolytes. These ionic liquids exhibit low viscosity, high conductivity, and thermal stability. The implementation of 1-but-3-enyl-3-methyl-imidazolium trifluoromethanesulfonate, [ButMIm]OTf, into DSCs gave the best photovoltaic performance. The results are fairly comparable to those reports for other popular ionic liquid electrolytes currently used in DSC field. An insightful discussion on the relationship between the structure of these new ionic liquids and the J-V characterization as well as electrochemical impedance measurement of DSCs will give more interesting information. The results are useful for large-scale outdoor application of DSCs.

Synthesis and thermophysical characterization of novel azide functionalized imidazolium based ionic liquids

Several new monocationic and unsymmetrical dicationic azide functionalized ionic liquids (ILs) were synthesized. FT-IR, 1H NMR, 13C NMR and elemental analyses were applied to identify the molecular structure of these compounds. The density of these ionic liquids was measured too. Unsymmetrical dicationic ionic liquids had higher density than monocationic analogues. The shear viscosity of a dicationic ionic liquid ((1-(2-azido-3-methyl-3H-imidazole-1-ium) propyl)-3-vinyl-3H-imidazole-1-ium di-dicyanamide) and its corresponding monocationic analogue were also measured. Further thermal behaviour and heat capacity of this dicationic ionic liquid were investigated by TGA and DSC techniques. TGA analysis suggested that the decomposition temperature increases with increasing the heating rate and unsymmetrical dicationic ionic liquid has good thermal stability (up to 502.4-533.6 K) and heat capacity (298-343 K).

Dimethyldioxirane (DMDO) as a valuable oxidant for the synthesis of polyfunctional aromatic imidazolium monomers bearing epoxides

Conventional organic salts represent a new paradigm in many areas of research. Despite their great potential, an improvement in their physicochemical properties requires the chemical modification of their intrinsic structure. Thus, an efficient pathway was developed for the preparation of polyfunctional imidazolium monomers incorporating aromatic rings and terminal epoxides which presented a real synthetic challenge. In this work, we describe the reactivity of various oxidizing agents to develop a strong, clean and powerful methodology to generate epoxidized salts. Various reaction conditions for the formation of the epoxides were investigated such as the role of the cation and the counterion as well as the influence of an aromatic and/or aliphatic linker chain. Finally, we have evaluated the thermal properties of these new polyfunctional salts by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).

Low viscosity azide-containing mono and dicationic ionic liquids with unsaturated side chain

A new class of azide-functionalized monocationic and unsymmetrical dicationic ionic liquids (ILs) with low viscosity and high liquid range was synthesized. All of the synthesized ILs, were characterized by FT-IR, 1HNMR, 13CNMR spectroscopies and elemental analysis. Some thermophysical properties including melting point, density, shear viscosity, decomposition temperature and heat capacity of the unsymmetrical dicationic azide functionalized IL with dicyanamide (DCA) were measured. To find the unique and general features of this dicationic IL, its properties were compared with the ones of the similar monocationic ILs. The results showed that the shear viscosity, density, thermal stability and heat capacity of the unsymmetrical dicationic IL are higher than monocationic analogues. In addition we found that the shear viscosity for the synthesized unsymmetrical dicationic IL containing azide group and DCA anion is 83.9?cP whereas the shear viscosities for other dicationic ILs reported in the literature are higher than 240?cP.

Ion-Tagged Oligonucleotides Coupled with a Magnetic Liquid Support for the Sequence-Specific Capture of DNA

The isolation of specific nucleic acid sequences is a major bottleneck in molecular diagnostics. Magnetic beads/particles are typically used as solid supports for the capture of DNA targets to improve sample throughput but aggregate over time resulting in lower capture efficiency and obstruction of liquid handling devices. Herein, we describe a particle-free approach to sequence-specific DNA extraction using a magnetic liquid support and ion-tagged oligonucleotide (ITO) probes. ITO conjugates were synthesized with the highest yields ever achieved for the radical thiol-ene coupling of a substrate and oligonucleotide. In addition to distinguishing nucleotide mismatches, the ITO and magnetic liquid-based approach was more sensitive than a commercial magnetic bead-based method for the capture of target DNA from a pool of interfering genomic DNA.

Bifunctional hydrophobic ionic liquids: Facile synthesis by thiol-ene "click" chemistry

We describe the facile, robust and orthogonal fabrication of a structurally comprehensive library of hydrophobic trimethoxysilyl-functionalized ionic liquids with C7-C15 thioether spacer, using thiol-ene "click" chemistry. The synthesized ionic liquids displayed very low glass transition temperatures, high thermal stability and were hydrophobic in character. And the ability to serve as surface coating agents was tested by immobilizing them on the surface of iron oxide supermagnetic nanoparticles and the organic loadings were quantified.

Synthesis and thermal characterization of mono and dicationic imidazolium pyridinium based ionic liquids

A series of monocationic and dicationic ionic liquids, in which each ionic liquid is associated with dicyanamide anion, are synthesized. The molecular structures of these compounds were identified by 1H-NMR, FT-IR and CHN analysis. Thermal behaviors of these ionic liquids were also investigated by thermogravimetry (TGA). The results suggested that all new ionic liquids have reasonable thermal stabilities, however, dicationic ionic liquids show more thermal stability than monocationics.
