The main classes of organic materials are as follows polyacetylene, polypyrrole, polyaniline, polyphenylene, and polythiophene. These materials share the characteristic that, on Ionic doping, electronic carriers are introduced into a delocalized ir system, rendering them very good conductors (98). As in the case of the oxides, this is a double-injection process, with counterions entering the poiymer structure. Several of the polymers can be produced by in situ electrochemical processes. Their microstructure is typicaiiy very dependent on preparation conditions. 

Some essential discoveries concerning the organization of the adsorbed layer derive from the various spectroscopic measurements [38-46]. Here considerable experimental evidence is consistent with the postulate that ionic surfactants form localized aggregates on the solid surface. Microscopic properties like polarity and viscosity as well as aggregation number of such adsorbate microstructures for different regions in the adsorption isotherm of the sodium dedecyl sulfate/water/alumina system were determined by fluorescence decay (FDS) and electron spin resonance (ESR) spectroscopic methods. Two types of molecular probes incorporated in the solid-liquid interface under in situ equilibrium conditions...
