Anion intercalation

This approach finds experimental support in FTIR measurements of the oxidation of PANI in organic solvents which indicate an anion intercalation mechanism for the second oxidation step. However, the IR findings may also be interpreted as support for the formation of a protonated imine structure... 

In the case of Ni(OH)2 and conductive polymer electrodes, solvent and anions intercalate into the electrode at anodic potentials. Electrochemical quartz crystal microbalance (EQCM) is a useful technique for monitoring the ingress and egress of solvent and anions in these materials. 

Single-walled carbon nanotubes SWNT anion intercalation. 

In the following cycles, the CV pattern does not show anymore the 4.15V anodic potential threshold, indicating a lowering of the anion intercalation overpotential. 

New anodic and cathodic peaks appear which indicates some degree of reversibility of the anion intercalation. Figure 5 and Figure 6 show the... 

Fig. 14.4 Schematic diagram showing the three-dimensional and two-dimensional solvated and unsolvated cationic and anionic intercalation compounds S = Solvent [23].

Many kinds of anion-intercalated LDHs have been prepared by precipitation at low supersaturation, including [19,24-27], NOa [28],... 

It was found that 23% of Co " was oxidized to Co ". The conversion of a brucite-like material to an LDH structure was observed in response to an increase in O2 partial pressure. Anionic species, such as NO3, were intercalated between the brucite-type layers of LDHs and the extent of anion intercalation increased as a function of O2 partial pressure.

Oxidation yields lamellar anion intercalation compounds that, again, depending on the electrolyte, may be solvated. Solvated anion compounds are formed, e.g., in acids, HA (HA = solvent), and in propylene carbonate (PC) electrolytes binary anion compounds can be obtained, e.g., in SOjClF electrolytes. ... 

A-TRISPHAT anion intercalates between two cationic complexes providing a onedimensional supramolecular chain. To our knowledge this example represented the first direct observation of chiral recognition between the A-TRISPHAT and any chiral organometallic species at least in the solid state. We also feel that this resolution originates from supramolecular control.
