“…The first stage corresponds to the loss of the solvent, water, and doping agent, the second one corresponds to the loss of the side alkyl substituent, and the third one characterizes the decomposition of the polymer chain skeleton. This thermal decomposition scheme is characteristic of the majority of PANI derivatives that have a side substituent . A sample of 2E3MPIn demonstrates two stages of thermal decomposition that start at 110 and 453 °C.…”

Intramolecular acid-catalyzed cyclization was suggested for the first time for a polyaniline derivative, namely, poly[2-(2-chloro-1-methylbut-2-en-1-yl)aniline] (PClPA), to give hitherto unknown poly(2-ethyl-3-methylindole) (2E3MPIn) in a high yield (81%). This is the first example of synthesizing a polymer of the indole series with 1,5-addition of monomeric units that are incorporated into the polymer structure. The physicochemical properties of the new polymer were studied. Its structure was confirmed by spectral methods and quantum-chemical calculations. The 2E3MPIn polymer showed good thermal stability compared to the starting PClPA polymer. A study of the photoluminescence of polymers showed that the emission spectrum of 2E3MPIn demonstrated a bathochromic shift (16 nm) and a considerable increase in the luminescence intensity in comparison to PClPA. The 2E3MPIn sample was found to possess photoconductivity. Irradiation of the polymer film increases the electrical conductivity by a factor of 2. The electrochemical properties obtained from the UV–vis spectrum and cyclic voltammograms suggest that 2E3MPIn has good electroactivity. A sample of 2E3MIn demonstrates a fine porous structure resembling a “sponge”. In addition, the PClPA and 2E3MPIn samples synthesized were used as sensitive materials in resistive moisture sensors. The 2E3MPIn polymer demonstrated a higher response than PClPA to changes in the environment humidity. The observed changes in the physicochemical properties of 2E3MPIn compared to PClPA confirm that the polyheterocyclization reaction occurs successfully and can be considered as an efficient way for synthesizing new functional polymers of the indole series.

“…The Co-N@NC catalyst demonstrated formylation of quinolones through transfer hydrogenation and formic acid dehydrogenation, revealing an enhanced H2 production rate along with selectivity and stability for transfer hydrogenation. The "produced water" formed as a byproduct during oil production is becoming an environmental problem by threatening public health 248 . These produced water contains several poisonous materials such as polycyclic aromatic hydrocarbons, organic acids, volatile hydrocarbons, bacteria, naturally occurring radioactive material (NORM), and heavy metals.…”

“…These produced water contains several poisonous materials such as polycyclic aromatic hydrocarbons, organic acids, volatile hydrocarbons, bacteria, naturally occurring radioactive material (NORM), and heavy metals. Polyindole nanoparticle-based electrorheological fluid (ER) proved the feasibility for reducing water production via conformance control technique, which makes the oil production operation more green, economical, and clean 248 . PIN nanoparticles were preferred due to the need for some unusual features regarding the size, synthesis method, and morphology to be applicable in an oil reservoir.…”
