Can thiophene be polymerized?
Recently, Lee et al. reported that thiophene in aqueous media can be effectively polymerized using iron (III) chloride (FeCl3) as a catalyst and hydrogen peroxide as an oxidant. Polythiophene nanoparticles with a narrow size distribution can be quantitatively obtained under ambient atmospheric conditions.
What is oxidative polymerization?
Chemical oxidative polymerization (COP) is used for synthesis of polymers (oligomers) from aromatic compounds such as aniline, pyrrole, phenols, diphenyl sulfide, thiophenols, and thiophene. ( 1) The monomers used in COP are characterized by pronounced electron donor properties with high oxidation tendency. (
Is thiophene conjugated?
Thiophene-Based Conjugated Polymers for Light-Emitting Diodes: Effect of Aryl Groups on Photoluminescence Efficiency and Redox Behavior | Macromolecules.
Which heteroatom is present in thiophene?
Thiophene is a sulphur containing heterocycle which resembles benzene in its chemical and physical properties.
How do you polymerize?
polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
What is electrochemical polymerisation?
Electrochemical polymerization or electropolymerization is based on the deposition of the polymer onto the surface of a solid electrode material. This occurs through a generally accepted mechanism that involves the formation of cationic radical by the oxidation of the monomer on the solid electrode material.
Is thiophene an organic compound?
Thiophene is a monocyclic heteroarene that is furan in which the oxygen atom is replaced by a sulfur. It has a role as a non-polar solvent. It is a mancude organic heteromonocyclic parent, a member of thiophenes, a monocyclic heteroarene and a volatile organic compound.
Is thiophene a derivative of benzene?
Thiophene was discovered as a contaminant in benzene. It was observed that isatin (an indole) forms a blue dye if it is mixed with sulfuric acid and crude benzene. The formation of the blue indophenin had long been believed to be a reaction of benzene itself.
Is thiophene a heterocyclic compound?
The aromatic five-membered heterocycles all undergo electrophilic substitution, with a general reactivity order: pyrrole >> furan > thiophene > benzene. Some examples are given in the following diagram.
Which pharmacological effect is produced by thiophene derivatives?
In medicine, thiophene derivatives shows antimicrobial [6], analgesic and anti-inflammatory [7], antihypertensive [8], and antitumor activity [9] while they are also used as inhibitors of corrosion of metals [10] or in the fabrication of light-emitting diodes in material science [11].
