Resumen:
In this chapter we describe a particular case of layer-by-layer (LbL) multilayer films
containing electrochemically or redox active components which can undergo
exchange of electrons with an underlying conducting substrate, and ion and solvent
exchange with the bathing electrolyte adjacent to the film.
In 1997 Laurent and Schlenoff [1] described the electrochemical response of
viologen groups in poly(styrenesulfonate)/poly(butanylviologen) LbL thin films and
Hodak et al. [2] showed the biosensor response to glucose with the enzyme glucose
oxidase (GOx) wired by ferrocene-derivatized poly-(allylamine) LbL multilayers.
Since then a large number of publications have described electrochemically
active polyelectrolyte multilayers (r-PEMs) including osmium pyridyl-bipyridyl
modified poly(allylamines) [315], poly(vinylpyridine) osmium complexes [16, 17],
ferrocene poly(allylamines [2, 1820], polyalkylviologens [2124], sulfonated polyaniline
[25], polythiophenes [26], polyoxo-metalates [2729], enzymes [2, 911, 16, 24,
3033] and redox proteins [3438], ferrocene-containing poly(amidoamine) dendrimers
[3944], Prussian Blue [4548], carbon nanotubes [49], metal nanoparticles [50],
and so on. The topic has been reviewed elsewhere [5153].
Electrochemically or redox active polyelectrolyte multilayers (r-PEMs) deposited on
conductive substrates (electrodes) and immersed in electrolyte solutions are of
particular interest since they have electron acceptors/donors that can exchange
electrons with the underlying conductive substrate and propagate redox changes along
the direction normal to the substrate. The charge imbalance due to the exchange of
electrons between the electrode and the r-PEM results in the transfer of charge across
the LbL layers and exchange of solvent and ions with the external electrolyte. In layered
thin films the stratified structure results in characteristic behavior and the fuzzy nature
of interpenetrated layers facilitates the transfer of charges along the film.films
