“…Electrodepositions of poly(3,4-dimethoxythiophene) (PDMT), poly(3,4-dipropyloxythiophene) (PDPT), poly(3,4-dioctyloxythiophene) (PDOT) and poly(3,4-ethylenedioxy-thiophene) (PEDOT) were carried out from solutions containing 0.05 M monomer and 0.1 M TBAPF 6 as the supporting electrolyte. The working electrodes were cycled from À0.6 to 1.1 V for PDMT, 1.05 V for PDPT and 1.05 V for PDOT or within the range from À1.3 to 1.0 V for PEDOT, at a scan rate of 40 mV s À1 .…”

“…Polythiophene and its derivatives undergo both p-and n-doping and therefore, this class of polymers has been widely considered for use in supercapacitors [1][2][3], microelectrochemical transistors [4,5], batteries [6,7], etc. The electrochemical doping consists in the creation of positive or negative charges along the polymer backbone (oxidation and reduction, respectively) with simultaneous insertion of charge compensating counter ions and it is manifested in spectral, mass and conductivity changes of the polymer.…”

“…[8] The chemical oxidative polymerization of pyrrole is very important as it is a more feasible route for producing polypyrrole on a large scale. In the last two decades, many efforts have been made to enhance the electrical properties and air stability of PPy using chemical oxidative polymerization with oxidizing agents such as ferric chloride, [8a-b,9] Chlorine (used to prepare granular-type PPy), [10] copper (II) perchlorate, [11] ferric tetrafluoroborate, [12] ferric sulfate, [13] and hexacyanoferrate (used to produce highly conducting PPy), [14] ferric perchlorate [15] and Cu(BF 4 ) 2 (used to produce improved PPy), [16] and colloidal dispersions of surfactant-stabilized polypyrrole prepared with ammonium persulfate, [17] pyridinium chlorochromate, tetraethylammonium tetrafluoroborate, [18] and ammonium ferric sulfate.…”

Summary: Benzoyl peroxide is used as an oxidizing agent for the first time in the synthesis of conducting polypyrrole. Synthesis of polypyrrole is commonly performed by chemical oxidative polymerization using water‐soluble oxidizing agents. In this work, polypyrrole was prepared using organic solvent‐soluble benzoyl peroxide as an oxidizing agent in the presence of p‐toluenesulfonic acid (p‐TSA) and sodium lauryl sulfate (SLS) surfactant via the inverted‐emulsion‐polymerization technique. During polymerization, SLS is converted to dodecyl hydrogensulfate (DHS) and incorporated on to polypyrrole along with p‐TSA dopant, indicating SLS is acting as emulsifier as well as dopant. The influence of synthesis conditions such as the duration of the reaction, the temperature, the concentration of the reactants, etc., on the properties of polypyrrole was investigated to determine the optimum conditions for the synthesis of polypyrrole salt. Polypyrrole was obtained in a reaction time of 1 h with high yield (154 wt.‐% with respect to pyrrole used) and good conductivity (2 S · cm−1). The conductivity of polypyrrole‐salt was found to be nearly the same even after seven months of storage at ambient temperature (1.7 S · cm−1). magnified image

The synthesis, spectral properties, and electropolymerization of hybrid gold nanoparticle core/carbazole dendron shells are reported. Ligand exchange of short‐chain alkane thiol stabilized Au‐NP is compared with direct synthesis using peripheral carbazole dendron ligands. Optical spectra, light scattering, TEM, and electron diffraction data confirm size, polydispersity, and composition. The direct synthesis route yields higher carbazole surface functionality. Higher dendron generation yields larger carbazole species on the surface. The advantage of a larger Au‐NP core is highlighted in terms of conformational mobility and electropolymerizability to form π‐conjugated polycarbazole species. Absorption and fluorescence shift is observed with the electropolymerized film. magnified image
