B is doublesided tape and C is a protective sheet of paper. (3) The bilayer device with a protective film is removed from the electrode. (4) The protective sheet is peeled off and the bilayer is ready to work. (Reprinted from Handbook of Organic Conductive Molecules ami Polymers, H.S.

In 1979, the formation of conductive polypyrrole films by the electrochemical oxidation of pyrrole was reported for the first time This work has stimulated intense and fruitful research in the field of organic conducting polymers. Further important conductive polymers are polythiophene, polyaniline and polyparaphenylene. The development and technological aspects of this expanding research area is covered... 

The synthesis of thin films of organic conducting polymers on a nanometer scale is one of the challenges of nanotechnology. Electrochemical poly-... 

Transport of samples to the analytical laboratory presents the staff of organizations conducting field frials with the most difficult problem and is the area where many studies have failed as a result of samples being lost, defrosted, or shipped to the wrong place. The number of experiences and ill fortune that have befallen many Field Trial Managers are too many to mention.

Researchers have already been using ink jet systems to print several types of novel materials, some of which have been used to fabricate circuit electrodes and interconnects. The four main types of materials used are metallo-organics, conductive polymers, molten metals, and metallic nanoparticle suspensions.

Most organic acceptors used in the preparation of organic conducting materials belong to a class of polycyano compounds. The reasons are quite obvious if the unique properties of the cyano group are taken into account. It is a very strong acceptor and has a very small size with minimal steric strain. (Note the rod-shaped form of C N group.)... 

In the search for new organic conducting materials, x-ray structure determinations of fused 1,2,5-selenadiazoles and 1,2,5-thiadiazoles have been carried out. Compounds (25a) and (25b) are planar molecules possessing a two-fold axis and mirror plane. Short C=N S and C N Se contacts connect each molecule in the crystal with four neighbors, forming a virtually planar sheet network (Figure 7), The sheets stack to form infinite layers with face-to-face overlapping between... 

Besides CdS, many other semiconductors have been deposited by the SILAR technique as well as organic conducting polymers, such as polypyrrole and polyaniline. For representative references and to locate some groups working in this field, see Refs. 188-195. 

CASA is a major research and education organization that focuses on publicizing the economic and social costs of substance abuse and on developing and providing effective tools for prevention, treatment, and law enforcement. The organization conducts annual conferences and produces annual reports as well as surveys and research studies. 

Conductivity has been widely used to estimate the degree of ionization of the extracted species (8, 97, 98). In relation with the supramolecular organization, conductivity is also a simple and powerful technique for following the variation in the structure of the extractant solutions and thus the formation of a third phase. Measuring the conductivity of the solvent phase, used as sensor in chemical engineering, therefore also provides efficient and reliable warning of the approach of a third-phase transition.
