“…Despite these advantages, the main drawback of PPy is its poor solubility in most common solvents which restricts its processability and makes it difficult to study optical and morphological properties of this polymer in solution phase. [28][29][30][31][32] An alternative route to enhance the solubility and processability of PPy is utilization of surfactant molecules as electrostatic stabilizers. A first approach toward increasing the solubility of PPy is to substitute pyrrole monomer at either carbon 18,19 or nitrogen 20,21 atoms and then polymerize the new derivatives into PPy.…”

Electrostatic stabilization concept based on an anionic surfactant, dodecylbenzenesulfonate (DBS -), was applied to prepare soluble and fluorescent polypyrrole (PPy) nanoparticles. The effect of N-substitution as well as synthesis conditions, i.e. surfactant to monomer mole ratio and oxidant addition type (one-step or multi-step) on the size, molecular weight, structure and spectroscopic properties of polymer nanoparticles was evaluated. PPy nanoparticles synthesized at surfactant to monomer mole ratio of 0.20:1 and five-step addition of oxidant show the most intense fluorescence, narrowest particle size and lowest molecular weight. FT-IR, UV-vis, XPS and ICP-OES confirmed that surfactant molecules are incorporated into the polymer structures. The synthesized polymer nanoparticles were classified into two categories based on their conductivities in solution phase and ICP-OES measurements: the indissociable polymer nanoparticles (PPy) which contain only anion dopant surfactants and dissociable polymer nanoparticles, poly N-methyl pyrrole (NmPPy) and poly N-phenyl pyrrole (NphPPy), which contain anion dopant and hydrophobically attached surfactant molecules. The experimental results of conductometry, XPS, ICP-OES and GPC were combined to propose polymer unit structures for all the synthesized polymer nanoparticles. The UV-vis and fluorescence measurements in different solvents were used to gain insight into the dipole moments of excited and ground states of polymer nanoparticles. Finally the potential application of the polymer nanoparticles in fluorescence sensors was investigated by recording their response to various chemical species and found that polymer nanoparticles have structure dependent sensing behaviors. PPy and NmPPy nanoparticles show the most sensitive response to C=S containing and nitro-aromatic compounds respectively, while NphPPy nanoparticles exhibit a selective and profound response to Fe +3 ion. The results of this work will benefit the scientists who are working on the synthesis and basic studies on soluble polymer materials and design of advanced fluorescence sensors.

“…By the inclusion of ketonic resin segments, PPy possessed T g and solubility 8. The same method was used to prepare soluble and conductive silicone tegomer/PPy copolymers 9. In this study, the effects of different types of ketonic resins on the conductivity, solubility, and thermal behavior of PPy/resin copolymers were investigated.…”

ABSTRACT:The chemical polymerizations of pyrrole in the presence of acetophenone and formaldehyde, cyclohexanone, acetaldehyde, and formaldehyde, cyclohexanone and formaldehyde, cyclohexanone, resorcinol, and formaldehyde, cyclohexanone and lignosulfonate formaldehyde, and cyclohexanone, pyrrole, and formaldehyde were accomplished with Ce(IV) salt in acetonitrile solutions. The roles of the resin type, the addition order of the reactants, and the concentrations of the pyrrole and resin on the solubility and conductivity of the resulting products were investigated.The cyclohexanone-acetaldehyde-formaldehyde resin/ polypyrrole copolymer had the highest solubility in dimethylformamide. The conductivity and solubility of the copolymers could be controlled by the Ce(IV)/pyrrole/resin molar ratio.

“…These copolymers have better solubility, 6 higher conductivity, 6,7 and higher contact angle values. 5,6 Besides, the electroinduced oxidative copolymerization of NVCz with methyl ethyl ketone-formaldehyde resin was studied and the copolymerization yield was found to be almost 10 times higher than the yield obtained by the redox polymerization method for the same Ce 41 concentration. 8 Electrolysis of NVCz solution usually coats the electrode surface with a green conducting PNVCz.…”

The redox system of ceric ammonium nitrate (Ce 41 ) and a,x-dihydroxy polydimethylsiloxane (DH.PDMS) was used to polymerize N-vinyl carbazole (NVCz) to produce poly(N-vinylcarbazole)-b-a,x-dihydroxy polydimethylsiloxane(PNVCz-b-DH.PDMS). The ratio of NVCz/ceric salt/DH.PDMS has an important effect on the properties of formed copolymers. White insulating PNVCz-b-PDMS copolymers with high fluorescence intensity are produced if the ratio of ceric salt/ NVCz is below 0.2. Green conductive PNVCz-b-PDMS copolymers are produced if this ratio is well above 0.
