Conducting Polymers

Abstract

Surprisingly, a large number of important topics in electrochemistry is not covered by up-to-date monographs and series on the market, some topics are even not covered at all. The series Monographs in Electrochemistry fills this gap by publishing indepth monographs written by experienced and distinguished electrochemists, covering both theory and applications. The focus is set on existing as well as emerging methods for researchers, engineers, and practitioners active in the many and often interdisciplinary fields, where electrochemistry plays a key role. These fields will range -among others -from analytical and environmental sciences to sensors, materials sciences and biochemical research.Information about published and forthcoming volumes is available at

Preparation of sulfur pigments based on the interaction of sulfur with aniline

“…A sulfur alloy with calcium oxide in various molar ratios was added to a pre-prepared solution of aniline hydrochloride. Then, with constant stirring, a solution of ammonium persulfate (n(C 6 H 5 NH 2 ): n((NH 4 ) 2 Quantitative determination of sulfur in organic substance. A sample of the material is weighed, placed in a round-bottomed flask, 3 drops of 4% NaOH solution are added and 10 ml of 30% hydrogen peroxide is added.…”

“…Illustration of delocalization (polaron lattice) of the emeraldine state: [2] Another application of these high surface area materials is to act as functional scaffolds for inorganic nanoparticles. The facile and reversible oxidation and reduction of polyaniline allows the polymer https://doi.org/10.26577/2218-7979-2017-10-1-78-83 to behave as either an oxidizing agent or a reducing agent when combined with different materials.…”

Synthesis of Soluble Polythiophene Partially Containing 3,4-Ethylenedioxythiophene and 3-Hexylthiophene by Polycondensation

“…The mixture was poured into sat.aq. NH 4 Cl and extracted with CHCl 3 . The extract was then successively washed with water.…”

Surfactant Formulations for Water-Based Processing of a Polythiophene Derivative

“…However, as is the case with many discoveries in chemistry and materials science, there are other individuals with which the identification and preparation of conjugated polymers can be first attributed. In 1862, for example, at the College of London Hospital, aniline was oxidized in a sulfuric acid solution by Henry Letheby to obtain a partially conductive material, most likely what is known today as a conjugated polymer, polyaniline (Inzelt, 2012). In electrochemical experiments, Dr. Letheby observed a green-colored precipitate forming at the anode that turned colorless after reduction and this material piqued his curiosity.…”

“…The absorption spectrum of a CP is thus dependent on the distribution of transition energies from the HOMO to LUMO of the excited electrons. Depending on the circumstances, the fate of an exciton in the CP can be one of three outcomes: it can relax thermally (1), it can re-emit the photon resulting in fluorescence or phosphorescence (2), or it can dissociate into distinct 7 hole and electron charge-carriers (3) (Inzelt, 2012). Exciton dissociation is the working mechanism by which photovoltaics produce a potential, and the opposite of the mechanism by which light-emitting diodes produce light, this will be discussed in more detail later in the chapter.…”
