Redox intercalation

Investigation of these properties should be one of the significant directions of future development of these compounds, especially worthwhile are the exploration of the possibility of removing the templates from the channels of the hon-eycomb-like material [Tl5(Ti2Cl9)][(Nb6Cli204)3(Ti3CL. )2] and the studies of this and other oxychloride materials as hosts in redox intercalation processes.

Chemical reagents can also be used to carry out redox intercalation reactions. Alkali metals in liquid ammonia and organometallic reagents such as n-butylhthium were among the earliest used. Other chemical reagents can be used to provide different effective activities of the alkali metal relative to the pure metal. A convenient sununary, developed for comparison of the reduction potentials for some common lithium reagents and common host lattices, is shown in Figure S. ... 

Reactions with Lewis bases are the other major class of redox intercalation reactions that have been explored with the FeOCl lattice. Pyridine, for example, reacts with FeOCl to form two compounds, (py)i/4FeOCl and (pyji/sFeOCl. Reactions of FeOCl with ammonia and alkylamines are among the earliest reported intercalation reactions of compounds with neutral layers. ...

A demonstrated method to insert polymer chains into host structures is by in-situ intercalative polymerization of a monomer using the host itself as the oxidant. FeOCl is one of the most convenient redox-intercalation hosts for a great variety of molecules including conducting polymers. The in-situ intercalative polymerization of pyrrole, 2,2 -bithiophene and aniline in the interlayer space of this material has been reported. The resulting intercalation compounds are composed...
