Electrochemical switching in anthraquinone-substituted carbon-pivot lariat ethers and podands: chain length effects in geometric and electronic cooperativity

Characterization of Anthraquinone-DerivedRedox Switchable Ionophores and Their Complexes with Li+, Na+, K+, Ca+, and Mg+Metal Ions

“…The transport ability of these ionophores has been increased in their reduced state because the anion and dianion are formed [21] as a result of reduction, and ionophores act as better carrier, which is clearly evident from Figure 6. In oxidized state, ionophore V 1 shows no transport but V 2 transports detectable amount of metal ions because the closer proximity of side chains provides a large number of binding sites.…”

Anthraquinone-based extended dendritic monomers: electrochemical comparisons

“…Half-wave potentials, E 1/2 (mV), for 1, 3, 4, and 5 at 298 K Compound It is well known [20][21][22] that anthraquinones and their derivatives undergo two sequential reversible electron-transfer reactions in aprotic solvents at 25 • C. Depending on the electron-withdrawing or -releasing character of the substituents attached to the anthraquinone, the measured half-wave potentials have been shown to vary within a relatively large potential window [23][24][25][26]. The half-wave potentials of the related redox active monomers 1, and 3-5 were measured ( Fig.…”

Novel 9,10-Bis(1,3-dithiol-2-ylidene)-9,10- dihydroanthracene Derivatives Bridged by a Crown Ether Unit at the 1,8-Positions: A New Type of Redox-switchable Hosts Undergoing Reversible Structural Changes

“…A diol (7) was synthesized in 40% yield from 1,8-dihydroxyanthraquinone (6) in two steps, 5 and the hydroxyl groups of 7 were protected as THP ether groups to give 8. Wittig-Horner reactions of 8 afforded biscondensation products (10a,b) in 54 and 24% yields, respectively, along with 9a,b.…”
