Electrochemical synthesis of poly(3-thiophene acetic acid) nanowires with water-soluble macromolecule templates

Abstract

The interactions between template molecules and monomers play a key role in the formation of PTAA nanowires.

Synthesis of Calixarene-Capped Silver Nanoparticles for Colorimetric and Amperometric Detection of Mercury (HgII, Hg0)

“…39 The 3-thiophene acetic acid ring of ThC exhibited bands at 1457 and 763 cm –1 , which are due to C=C and Cα–H of the ring, respectively. 40 The 1 H NMR spectra of the compound ThC are shown in Figure S4 (Supporting Information), which exhibited two doublets at δ 4.23 and 3.54 ( J = 13.54 and 13.54 Hz) for the Ar–CH 2 –Ar methylene protons, suggesting that the compound exists in cone conformation in the solution. 41 The aromatic protons of the calix unit appeared as two doublets and two triplets at δ 7.18 (d, J = 7.54 Hz), δ 7.06 (d, J = 7.61 Hz), δ 6.89 (t, J = 7.60 Hz), and δ 6.75 (t, J = 7.52 Hz), respectively, which supports the cone conformation of the calix unit.…”

Optimal strategy based on radiation chemistry for facile and direct synthesis of poly(3-thiophene acetic acid) polymers in water and dichloromethane

“…31 In this context, poly(3-thiophene acetic acid), PTAA, as one of the most important polythiophene derivative members, is an excellent and practical conducting polymer due to its various interesting properties such as high conductivity, good thermal and environmental stability, and biocompatibility. 33 The particular importance and usefulness of this conjugated material result from the presence of the carboxyl acid moiety all along the polymer chains. PTAA polymers are appropriate for the preparation of nanocomposites based on conjugated polymers and metal oxides, in particular PTAA-Fe 3 O 4 nanocomposites.…”

“…As a consequence, by the way of electrochemical methods, PTAA can't be produced in water and is mainly electropolymerized in organic media such as boron triflouride diethyletherate (BFEE) and trifluoroacetic (TFA). 33,[41][42][43] Therefore, with this in mind and based on our previous radiation chemistry-based methodologies, we report here for the first time the use of two different radiolytic routes to induce the oxidative polymerization of 3-thiophene acetic acid (TAA) in a one step synthesis, starting from monomers dissolved either in water or in dichloromethane and without using oxidizing agents or any prior esterification (Scheme 1). In this work, we present a simple way to synthesize and then to modulate the morphological nanostructures of PTAA conducting polymers (PTAA H 2 O and PTAA CH 2 Cl 2 ) thanks to the use of oxidizing species generated from g-radiolysis of water and dichloromethane solvents.…”

Micro/nanostructures of PANI obtained in the presence of water soluble polymers and their electrochemical sensing properties

“…Water-soluble macromolecules, such as HEC, 21 PAM, and Cs 20 are chosen to be the template because of HEC, PAM and Cs molecules have chain shaped structures with many -OH groups and -NH 2 groups, these groups can interact through hydrogen bonding interactions with -NH 2 groups of aniline monomers. 20 Another kind of PANI nanostructure is produced by the polymerization of aniline monomers in the presence of poly(acrylic acid) (PAA). 2 (inset) and no wire is observed on the surface of the lm.…”
