Methyl viologen neutral MV. 1. Preparation and some properties

Interfacial redox centers as origin of color switching in organic electrochromic device

“…Viologen is an organic compound for potential use in flexible electrochromic devices due to its activity in reversible redox reaction and excelent electron accepting nature. In other words, Viologens [9], [11][12][13][14] are reducible materials used in solid-state electrochromic devices, which may undergo one-or two-electron reductions. [9], [11][12][13][14] Ease of processing and use have stimulated intensive research into the electrochromic properties of viologens.…”

Photopolymerization of Methyl Methacrylate with Methyl Viologen-Na2S2O4-CCl4 in Aqueous-Organic, Two-Phase System

“…MV, however, could not be isolated from the polymerization system because of its unstability. 10 In order to clarify whether MV + · reacts with 780 CC1 4 or not before the disproportionation reaction the dark-polymerization was carried out under the same conditions as that of the photopolymerization. In these conditions, however, MMA did not polymerize at all.…”

Dye-Sensitized Molecular Charge Transfer Complexes: Magnetic and Conduction Properties in the Photoexcited States of Ni(dmit)2 Salts Containing Photosensitive Dyes

“…It is the unique feature common to these salts that the crystals most developed along the cation-anion interactions, in contrast to other Ni(dmit) 2 semiconducting salts. It is often the case with the Ni(dmit) 2 salts that their crystals mostly develop in parallel with the Ni(dmit) 2 sheets or columns in which the Ni(dmit) 2 anions closely interact with each other.…”

“…As the conducting and magnetic properties of these salts are expected to be governed by the Ni(dmit) 2 anions, resistivity should be measured in the direction where the anions aggregate themselves to form conduction pathways of columns or sheets. However, in these salts, the dimensions of the single crystals in such directions were too small to carry out electrical measurements, suggesting that the interactions between the anions are not so large compared with other intermolecular interactions.…”

“…Some kind of aromatic amines and bipyridyl derivatives have attracted attention in various research fields for a long time as photosensitive dyes, which exhibit strong reducing or oxidizing abilities under irradiation [1][2][3][4][5][6][7][8]. Accordingly, they induce charge transfer (CT) between adjacent chemical species and the dyes in the photoexcited states in both solution and solid.…”
