A short review on the synthesis, characterization, and application studies of poly(1-naphthylamine): a seldom explored polyaniline derivative

Synergistic Performance of Sonolytically Synthesized Poly(1‐naphthylamine)/TiO2 Nanohybrids: Degradation Studies of Amido Black‐10B Dye

“…To overcome this problem, researchers have focused on designing conducting polymer sensitized semiconductor oxides which have shown improved photocatalytic performance Conducting polymers such as polyaniline (PANI), polypyrrole (Ppy), polythiophene (PTh), poly(1‐naphthylamine) (PNA), poly(o‐toluidine) (POT), polycarbazole (PCz) are well investigated for their excellent photo‐physical, photo‐chemical, electrochemical and structural properties. When combined with semiconductor nanoparticles, they act as charge reservoirs and prevent the recombination of photogenerated electron/hole pairs …”

Effect of structural factors on the physicochemical properties of functionalized polyanilines

“…In fact, leucoemeraldine contains no oxidized nitrogen atoms, therefore its conductivity is low, 10 À8 to 10 À10 S cm À1 . 109 During oxidation and with an increase in the number of charge carriers, the electrical conductivity increases. Emeraldine, a stable semioxidized form of PANI, has high conductivity (10-100 S cm À1 ).…”

“…27 The absorption maxima of poly-ortho-phenylenediamine are shied relative to those of PANI towards shorter wavelengths due to the steric effect of the functional group. 85,109,110 The hypsochromic shi of the maxima in the spectra of poly-metaaminophenol and poly-ortho-phenylenediamine, despite the strong electron-donating effect, occurs because they exist in the form of a ladder-type structure, which decreases the degree of conjugation of the polymer chain, similarly to the majority of PANI derivatives.…”

Synthesis of novel poly(1‐naphthylamine)‐silver nanocomposites and its catalytic studies on reduction of 4‐nitrophenol and methylene blue

“…Even though PAni and PNA belong to the same family of polyaromatic amines, their chemical and physical properties are different owing to the difference in their polymer backbone. Being a PAni derivative, PNA possesses all advantages like ease of synthesis, tunable redox properties, pH‐sensitive electrochromic properties, and easy doping‐dedoping characteristics . A major limitation of PAni is its low thermal stability and poor processability, which can be improved by introducing substituents on the ring …”
