Electrostatic interactions within mixed-valent compounds

Ferrocenyl‐Pyrenes, Ferrocenyl‐9,10‐Phenanthrenediones, and Ferrocenyl‐9,10‐Dimethoxyphenanthrenes: Charge‐Transfer Studies and SWCNT Functionalization

“…Contrary to smaller counter ions such as [PF 6 ] − or [Cl] − , [B(C 6 F 5 ) 4 ] − stabilizes highly charged species in solution and minimizes ion pairing effects . The shielding of the electrostatic interactions among the two redox sites is achieved by the ion pairing with the electrolyte's counter‐ion hence a minimization of this effect leads to an increase in the observed redox potential splitting . The voltammetry measurements were performed at 25 °C.…”

“…[74][75][76][77] The shielding of the electrostatic interactions among the two redox sites is achieved by the ion pairing with the electrolyte's counter-ion hence am inimization of this effect leads to an increasei nt he observed redoxp otential splitting. [78] The voltammetrym easurements were performed at 25 8C. All potentials are referenced to the FcH/FcH + redox couple.…”

Tailoring of the Frontier Orbital Character in Co2+/3+ Complexes with Triarylamine Substituted Terpyridine Ligands

“…The reference electrode was built from a silver wire inserted into a solution of 0.01 mol L ‐1 [AgNO 3 ] and 0.1 mol L ‐1 [ n Bu 4 N][B(C 6 F 5 ) 4 ] in acetonitrile, in a Luggin capillary with a Vycor tip. This Luggin capillary was inserted into a second Luggin capillary with a Vycor tip filled with a 0.1 mol L ‐1 of [ n Bu 4 N][B(C 6 F 5 ) 4 ] in acetonitrile, propylene carbonate and dichloromethane, respectively , , . The working electrode was prepared by polishing on a Buehler microcloth first with a 1 µm and then with a 1 / 4 µm diamond paste before every measurement.…”

Zwitterionic Mixed Valence: Internalizing Counteranions into a Biferrocenium Framework toward Molecular Expression of Half‐Cells in Quantum Cellular Automata

“…The bound CN À ion resulted in deeper parabolas with al arger energy gap, while the bound F À ion resulted in further changes in the parabola shape. The electronicm ixing coefficients [2] (a = H AB /u max )d ecreased in the order 1 + + > 1 + + -CN À > 1 + + -F À ( Table 2).…”

“…[1] By virtue of their simple structuresc ontaining two redoxs ites linked by a pbridge, mixed-valence (MV) molecular compounds are regarded as an essential platform for understanding ICT mechanisms at zero driving force (i.e.,i ntervalence charge transfer (IVCT)). [2,3] Althoughf undamental knowledge has deepened, [4] new concepts have been introduced to mixed valency.P hotoswitchable MV compounds have been developed to probe the electronicc oupling (H AB )a cross photoisomerizable bridgesf or conductivity control of molecularw ires, [5][6][7][8] and proton-coupled MV compounds with hydrogen-bonded bridges have emerged for investigation of the synchronized motion between an electron and ap roton. [9][10][11][12][13] In the contexto fh ost-guest chemistry, the effects of supramolecular interactions on IVCT properties have been reported for ac yclodextrin and crown ethers.…”
