Synthetic Principles for Bandgap Control in Linear pi-Conjugated Systems.

Color Control in π-Conjugated Organic Polymers for Use in Electrochromic Devices

When asked to explain the importance of the discovery of conducting polymers, I offer two basic answers: first they did not (could not?) exist, and second, that they offer a unique combination of properties not available from any other known materials. The first expresses an intellectual challenge; the second expresses a promise for utility in a wide variety of applications.

Semiconducting and Metallic Polymers: The Fourth Generation of Polymeric Materials (Nobel Lecture).

Electrochemical energy storage systems (batteries) have a tremendous role in technical applications In this review the authors examine the prospects of electroactive polymers in view of the properties required for such batteries Conducting organic polymers are considered here in the light of their rugged chemical environment: organic solvents, acids, and alkalis The goal of the present article is to provide, first of all in tabular form, a survey of electroactive polymers in view of potential applications in rechargeable batteries It reviews the preparative methods and the electrochemical performance of polymers as rechargeable battery electrodes The theoretical values of specific charge of the polymers are comparable to those of metal oxide electrodes, but are not as high as those of most of the metal electrodes normally used in batteries Therefore, it is an advantage in conventional battery designs to use the conducting polymer as a positive electrode material in combination with a negative electrode such as Li, Na, Mg, Zn, MeH{sub x}, etc 504 refs

Electrochemically Active Polymers for Rechargeable Batteries.

This article summarises the industrial applications of poly-(3,4-ethylenedioxythiophene)
				(PEDT, PEDOT). The basic chemical and physical properties of PEDT are discussed to outline the fundamentals which lead to PEDT as a highly valuable electric and electronic material. PEDT applications are reviewed depending on the two different ways of preparation: in situ polymerisation of the monomer, usually carried out by the user, and applying the prefabricated polymer in the form of its water-based complex with poly(styrene sulfonic acid). Several applications like antistatic coatings, cathodes in capacitors, through-hole plating, OLED's, OFET's, photovoltaics, and electrochromic applications are discussed in detail.

Poly(alkylenedioxythiophene)s—new, very stable conducting polymers

Electrochemical and spectroscopic characterization of polyalkylenedioxythiophenes

The invention relates to dispersions of polythiophenes made up of structural units corresponding to the following formula ##STR1## in which R 1 and R 2 independently of one another represent hydrogen or a C 1-4 alkyl group or, together, form an optionally substituted C 1-4 alkylene group, in the presence of polyanions, to the production of these dispersions and to their use for the antistatic treatment of plastic mouldings.

Polythiophene dispersions, their production and their use

The invention relates to new polythiophenes containing structural units of the formula ##STR1## in which A denotes an optionally substituted C 1 -C 4 -alkylene radical, their preparation by oxidative polymerization of the corresponding thiophenes and the use of the polythiophenes for imparting antistatic properties on substrates which only conduct electrical current poorly or not at all, in particular on plastic mouldings, and as electrode material for rechargeable batteries

Polythiophenes, process for their preparation and their use

Poly(3, 4-ethylenedioxythiophene) (PEDT) is a new polymeric organic conductor which, when combined with polystyrene sulphonic acid, produces a system that can be processed as an aqueous solution and yields effective antistatic coatings for films. The antistatic effect is achieved with coating weights of just a few mg PEDT/m2, resulting in films with a surface resistivity of 106 ω/□.
