Plasma Polymerization of 2-Iodothiophene

Abstract

Continuous wave rf plasma polymerization of 2-iodothiophene has been studied using X-ray photoelectron spectroscopy (XPS), X-ray absorption near-edge spectroscopy (XANES), and Fourier transform infrared spectroscopy (FTIR). The variation in plasma polymer stoichiometry and the extent of monomer fragmentation are found to be critically dependent upon the electrical discharge power.

Doping of polythiophene by microwave plasma deposition

“…Many polyheterocyclic aromatic compounds having good thermal stabilities and high electrical conductivities could also be added to the list of organic conducting polymers. Polythiophene (PTh) [6] is one of the polyheterocyclics widely studied and plasma polymerization methods have also been utilized for their synthesis to alleviate problems associated with insolubility of PTh in most organic solvents [7][8][9][10][11][12][13][14][15][16][17] which usually result in difficulties in the processing stage. PTh exhibits high electrical conductivity upon doping, therefore, potential applications exist in many areas including sensors, organic light emitting diodes, solar cells, applications requiring photonic and conductive properties and polymeric batteries.…”

Polymerization of halogenated anilines by plasma

“…Particularly, one important studied area has been the mechanisms of the electric charge motion along the polymers promoted by the halogenated dopants. Many doping strategies have been studied in this context, including experimental and theoretical works on polymers with halogens bonded to the aromatic rings 10–15…”

Photochemical conversion of 2,5-diiodothiophene condensed on substrates to oligothiophene and polythiophene thin films and micro-patterns

“…For the samples prepared by other direct deposition methods, multiple sulfur species due to dissociation of C -S bond or aliphatic carbons are often observed [11,12]. In a similar photochemical work carried out with a high-intensity UV laser at a low temperature in a rough vacuum, about 30% of the C -S bonds are broken and considerable carbonyl defects are formed Fluorescence microscope image of the photochemically produced patterns on a melt-cast polyethylene film.…”
