Apolar Solvent

Triflic acid dispersed in an apolar solvent exhibited a superior doping effect and stability on carbon nanotube electrodes. The carbon nanotube electrode-based perovskite solar cells exceeded the metal electrode-based counterpart in terms of efficiency.

The Stability

Photodynamic therapy is an emerging treatment of tumor diseases. The complexes with γ-cyclodextrins (γ-CD) and fullerenes or their derivatives can be used as photosensitizers by direct injection into cancer cells. Using molecular mechanics and molecular dynamics methods, the stability and the geometry of the 2:1 complexes [(γ-CD)2/C70] are investigated analyzing the differences with the analogous C60 complexes, studied in a previous theoretical work and experimentally found to be much less efficient in cancer therapy. The inclusion complex of γ-CD and C70 has a 2:1 stoichiometry, the same as C60, but is significantly less stable and displays an unlike arrangement. In vacuo, mimicking an apolar solvent, the complex is compact, whereas in water the two γ-CDs encapsulate C70 forming a relatively stable complex by interacting through their primary rims, however exposing part of C70 to the solvent. Other higher-energy complexes with the γ-CDs facing different rims can form in water, but in all cases part of the hydrophobic C70 surface remains exposed to water. The stability and arrangement of these peculiar amphiphilic inclusion complexes having non-covalent interactions in water can be an important key for cancer therapy to enhance both the solubilization and the fullerene insertion into liposomes or cell membranes.

Solvation of lauric acid [CH3(CH2)10COOH] has been investigated in different solvents (apolar, polar-aprotic, and protic solvents) by infrared absorption and Raman scattering in a large molar ratio range in order to investigate the intermolecular interactions between fatty acids and molecules of different types of solvents. Temperature effects on these mixtures have also been investigated between 24 and 95°C. We have especially concentrated on the carbonyl stretching region (between 1600 and 1800 cm−1), the hydroxyl stretching region (between 2500 and 3600 cm−1), and the C-H stretching region (2800–3000 cm−1). Chloroform behaves, with respect to lauric acid, almost as an apolar solvent. In acetone and in DMSO, a dynamical equilibrium between both cyclic dimers and H-bonded lauric acid molecules with solvent molecules seems to occur, the proportion of the two species depending on the lauric acid concentration. Cyclic dimers appear for a lauric acid: DMSO molar ratio x > 0.5 ( x > 0.2 in acetone). In alcohols, cyclic dimers are present from x &thkap, 0.2. For x < 0.2, two different complexes exist, in contrast with results from recent literature. These may be monosolvate and disolvate complexes. When the alcohol is deuterated, exchange between hydroxyl groups of both components is observed. Finally, Raman scattering appears as a powerful tool to clarify IR spectra in the case of solvated carboxylic acids.
