EDOT/3,4-Ethylenedioxythiophene Description

?

Spectroscopic and electrochemical studies of the oligomers revealed some general dependencies of their electronic properties on the total number and position of EDOT groups. It was the number of consecutive EDOT units rather than total number of these units which was found to have the most profound effect on electronic energy gap and conjugation length. This influence originates from the especially strong planarization induced in the conjugated backbone by the incorporation of EDOT units.

?

In contrast, incorporation of thiophene units was found to result in loss of the conformational stabilization. This phenomenon was analyzed using the natural bond orbital computational approach, which revealed the predominantly hyperconjugative nature of the EDOT-induced conformational stabilization. Whereas shorter oligomers, in agreement with the general consensus, were found to be inert toward electrochemical polymerization due to low reactivity of electrochemically generated cation radical and dication species, the longest oligomer showed an unprecedentedly efficient electropolymerization to yield a stable thin film of an electroactive polymer.

3,4-ethylenedioxythiophene(EDOT) application

?

3,4-Ethylenedioxythiophene is used as a monomer to synthesize the conductive polymers and used as a reductant in the one-pot synthesis of gold nanoparticles from chloroauric acid, as starting material used in palladium-catalyzed mono and bis-arylation reactions and in the synthesis of conjugated polymers and copolymers, with potential optical applications. It is also used in redox activity, electroactivity and conductivity.

?

Thiophene, also known as thiofuran, is a cyclic compound containing four carbon atoms and one sulphur atom in a ring. It is a toxic, flammable, highly reactive, colorless liquid insoluble in water (soluble in alcohol and ether) and melts at 38 C, boils at 84 C. It is used as a solvent and chemical intermediate. Its derivatives are widely used in manufacturing dyes, aroma compounds and pharmaceuticals. They are used as monomers to make condensation copolymers.

?

Due to extended pi-electron cloud overlaps, organometallic molecules or aromatic oligometers such as anthracene exhibit semiconductor properties. Conductive polymers have extended delocalized bonds that creates electrical conductivity when charge carriers generated make positive charges (holes) and negative charges (electrons) move to opposite electrodes. Doping is the intentional impurities in a pure semiconductor to generate charge carriers. The transportation of charges is responsible for fluorescence and electrical energy. These can form well-ordered thin crystalline films. Organic semiconductors have some merits of self radiation, flexibility, light weight, easy fabrication, and low cost. Organic electroluminescence materials have lead to the rapid development of photovoltaic and display devices such as organic solar cells, biosensitizers, OLED(Organic Light Emiting Diode), OTFT(Organic Thin Film Transistor), Wearable Display, and e-Paper. Some examples of organic electroluminescence materials are:
# Oligomer Electro Luminescence Materials # 8-hydroxyquinoline aluminum
# Anthracene
# Pentacene
# Penyl substituent cyclopentadiene derivatives
# Phthaloperinone derivatives
# Perylene derivatives
# Rubrene

# Polymer Electro Luminescence Materials # Polyanilines
# Poly(p-phenylenevinylene)s
# Poly(thiophene)s
# Poly(alkylfluorene)s
# Poly(acetylene)s


3,4-Ethylenedioxythiophene is a monomer for the manufacture of conjugated polymer [ poly(3,4-ethylenedioxythiophene)] for the applications of redox activity, electroactivity, and conductivity.
