“…This is the case in which the C 2 atom is bonded to another carbon atom, suggesting the coupling at the 1,2-position. Additionally, we observed [17,18]; the polymer structure with coupling at the 2,2-3,3 positions has also been proposed though its structure was not addressed in Scheme 1 [17,19]. Fig.…”

“…First and second peak correspond to p-p* transition and n-p* transition while the third one is due to polaronic excitations (effect of doping). 37 On the other hand, PIn synthesized by microwave (using APS) consists of similar absorption peak and almost same position [cf. Figure 3 .…”

A facile and rapid enhanced microwave-assisted route for one-pot synthesis has been developed to polymerize indole moiety using two different oxidizing agents for 60 s exposure at 30 6 1 C. As-synthesized conducting polyindoles, obtained by varying the synthesis process and oxidant, have been well characterized by various techniques. UV-vis, FT-IR, and NMR have been used for their structural analysis while gel permeation chromatography, thermogravimetric analysis, and conductivity measurement to evaluate their enhanced properties and to perform a comparative study. Morphological texture of polyindole synthesized via different techniques has studied by scanning electron microscopy analysis. PIn synthesized by KIO 3 (microwave synthesis) exhibit interconnecting texture which may be due to high level of supersaturation of solution under the influence of microwave irradiation. Thereafter, electrical property of spin-coated thin film of polyindole is examined using four probe method and Al metal/semiconducting material Schottky junction. Microwave-assisted polymer shows better performance for Schottky devices due to difference in charge transport, morphological texture, and distribution of M n . The PIn synthesized via microwave irradiation with better charge transport across the metal/polymer interfaces shows the potential of this technique for synthesis of such polymers with enhanced electronic properties.

Polyindole (PIn) nanoparticles were synthesized through an emulsion polymerization technique in this study and then examined as an anhydrous semi‐conducting electro‐responsive material. Their surface morphology and chemical structure were observed with high‐resolution scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. When dispersed in silicone oil, the electrorheological (ER) properties of the PIn particles were examined using a rotational rheometer with both steady shear and oscillatory tests under various applied electric field strengths with direct observation using an optical microscope. Flow curves of shear stress as a function of shear rate were well fitted using the Cho‐Choi‐Jhon model. Dielectric analysis was also performed to examine the permittivity and loss factor in relation to the ER effect. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46384.
