Redox chemistry of substituted benzenes: the one-electron reduction potentials of methoxy-substituted benzene radical cations

Synthesis, DNA-binding and photocleavage studies of ruthenium complexes [Ru(bpy)2(mitatp)]2+ and [Ru(bpy)2(nitatp)]2+

“…The redox potentials for the ground and excited states (estimated from the lowest limit of the DE 00 energy, i.e., the emission maximum) of the two complexes together with similar complexes are compared in Table 1. The redox potential of the excited states were 1.21 V and 1.29 V for complexes 1 and 2, respectively, which is higher than the oxidative potential of guanine 1.13 V [55], indicating that both complexes can generate oxidative damage to DNA. However, the redox potentials for the excited states should be regarded as approximation because the orbitals involved in the spectroscopy and electrochemistry are different.…”

Radiation Chemistry in Chemically Amplified Resists

“…158,[161][162][163][164][165][166][167][168] The absorption maxima of radical cations of phenol and p-cresol are at 440 and 430 nm, respectively. 169) The radiation chemistry of the model compounds for protected PHS such as methoxybenzene (anisole), methoxytoluene, and dimethoxybenzene has also been intensively investigated using pulse radiolysis, [170][171][172][173] photolysis, 174,175) chemical oxidation, [176][177][178] and electrochemical methods. 179,180) Radical cations of p-methoxytoluene are observed at 440 175) and 450 nm 174) in acetonitrile and at 460 nm in 1,2-dichloroethane.…”

“…172) Those of methoxybenzene are observed at 430 nm in water. 170,171,173) The deprotonation of radical cations of these model compounds has also been investigated. 162,175,178,[181][182][183] The pK a of the dimethoxytoluene radical cation is 0.45 in acetonitrile.…”

Understanding the redox shuttle stability of 3,5-di-tert-butyl-1,2-dimethoxybenzene for overcharge protection of lithium-ion batteries

“…Redox shuttle additives have been proposed for overcharge protection of secondary lithium-ion batteries for decades [1][2][3][4][5][6]. Generally, the redox shuttle molecule can be reversibly oxidized and reduced at a defined potential slightly higher than the endof-charge potential of the positive electrode.…”
