“…This unique process, according to their features, namely potential values comparable to the two monoelectronic peaks observed in solution, its fashion (large separation of peaks and width) and the slow kinetics behavior, could be related to the formation of not only aminyl radical cations, but also dications. 29,30 Besides, the electrochemically p-doped film would be somehow stabilized by delocalization of the electron density as a result of solid state surrounding and the favored planarity of the m-MTDATA's cores in LB film state (i.e. improved electron conjugation).…”

Here we report on the electroactivity properties of Langmuir-Blodgett (LB) films of the hole-transport molecule 4,4',4''-tris[3-methylphenyl(phenyl)amino] triphenylamine (m-MTDATA). Fairly stable Langmuir films at the air-water interface are accomplished, despite the non-amphiphilic character of the molecule. The reflection-absorption infrared spectroscopy (RAIRS) and Fourier transform infrared (FT-IR) analysis revealed that the molecules arrange with no neat preferential orientation, in agreement with the amorphous glassy nature of this starburst molecule. However, there is a tendency of the molecules to organize in a more planar conformation due to the intermolecular stacking induced by the LB technique. On the other hand, the fundamental electrochemistry (by cyclic voltammetry, CV) of the films is also analyzed. The CV studies of both solution and films reveal that both the solid state and the electrolyte's anions clearly affect the m-MTDATA's electroactivity, exhibiting a unique and broad redox process instead of the two reversible oxidations observed in solution. The oxidization mechanism is discussed. Finally, the spectroelectrochemistry studies evidence that the oxidization of the films leads to new absorption bands, among which the emerging bands in the NIR region ascribed to intervalence charge transfer (IVCT) between the generated aminyl radical cations should be pointed out.

“…The use of a weakly polar noncoordinating solvent or solvent mixture like kerosene [18], toluene [16,19] or 1,2-dichlorobenzene [12,13] for electrode modification was rather rare. For instance, voltammetry of 1,3,5-tris [4-[(3-methylphenyl) phenylamino]phenyl]-benzene dissolved in toluene droplets deposited on the electrode surface exhibits some anion sensitivity in the presence of nitrate or perchlorate anions [18]. In our earlier study we reported that voltammetry of the electrode modified with t-butylferrocene in toluene shows no ion sensitivity due to expulsion of an electrogenerated cation into the aqueous solution [16].…”

Voltammetry of Mn(III) Porphyrin in Trihexyl(tetradecyl)‐phosphonium Tris(pentafluoroethyl)trifluorophosphate Supported Toluene in Contact with an Aqueous Electrolyte

Voltammetry of manganese tetraphenylporphyrinato chloride in trihexyl(tetradecyl)phosphonium tris(pentafluoroethyl)trifluorophosphate solution in toluene reveals its unexpectedly low diffusion coefficient. UV-vis spectra confirm significant Cl À exchange with large phosphate anion at the axial position of the complex. Experiments performed with a glassy carbon electrode covered by a liquid film of the same solution and immersed in an aqueous electrolyte solution show a peak potential dependence on the nature and concentration of the aqueous electrolyte anion described by a Nernst type equation. Electron transfer is followed by anion expulsion where the anion effect results from the lability of the axial coordination site of the porphyrin and from spontaneous ion exchange.
