“…In the FTIR spectrum, the peak at 796 cm -1 is due to out of plane bending vibration of C-H on para-disubstituted rings which is consistent with the proposed tetra-substituted benzene ring system [14,15]. The benzene ring connected at the para position with quinone diimine moieties and the out of plane bending vibration is evidenced by the presence of the absorption band at 830 cm -1 [16,17].…”

We report on the preparation, characterization and property evaluation of molecularly imprinted polyaniline nanoparticles that can be used for selective recognition of aldrin. Molecularly imprinted polyaniline (MI-PANI) nanoparticles were prepared by inverted emulsion polymerization using aldrin as a template and aniline as a functional monomer. Materials prepared were characterized using UV-VIS, FTIR and NMR for structural elucidation. Comparison of spectra data from UV-VIS, FTIR and NMR confirmed that aldrin was incorporated successfully into the polymer matrix. AFM and SEM were used to evaluate morphological characteristics. Both AFM and SEM revealed that the particles prepared were spherical in nature. The particle size was in range 60-100 nm for non-imprinted which increased to between 500-1500 nm for the imprinted. The surface morphology was observed to change from smooth to rough on incorporating aldrin molecules. Electrical properties were evaluated using a four-point probe coupled to a source meter. Non-imprinted materials showed an electrical conductivity of 4.149 S/cm that reduced to 0.546 S/cm in MI-PANI. The values of KD and Bmax were found to be 0.6 ng/L and 0.799 ng/L respectively. Adsorption characteristics of aldrin and DDT were investigated to ascertain the selectivity of the imprinted nanoparticles. The results showed the distribution coefficient of for DDT and Aldrin to be 0.76 ng/ng and 1.31 L/ng respectively. This is indicative that the imprinted nanoparticles had a stronger affinity for Aldrin than DDT.

“…The processable conducting polymers are generally prepared by aqueous colloidal dispersion in the presence of water‐soluble anion surfactants (acid dopants) and form ionic bonds with the acid dopants (Figure ) . Frequently used dopants include camphor sulfonic acid (CSA), p‐toluene sulfonic acid (p‐TSA), dodecylbenzene sulfonic acid (DBSA), polyvinyl sulfonic acid (PVSA), poly(2‐acrylamido‐2‐methyl‐1‐propane sulfonic acid) (PAMPS) and polystyrene sulfonic acid (PSS) . Fluorosurfactant such as perfluorooctane sulfonic acid (PFOS) and poly(perfluoroethylene perfluoroethersulfonic acid) (PFFSA) can also be used as acid dopants.…”

This review focuses on the importance and the key functions of anode interfacial layers based on conducting polymers in organic and organic–inorganic hybrid perovskite optoelectronics. Insertion of a buffer layer between electrode and semiconducting layers is the most common and effective way to control interfacial properties and eventually improve device characteristics, such as luminous efficiency in light‐emitting diodes and power conversion efficiency in solar cells. Conducting polymers are considered as one of the most promising materials for future organic and organic–inorganic hybrid electronics because of advantages such as a simple film‐forming process and ease of tailoring electrical and physical properties; as a result, using these polymers is compatible with the production of large‐area, low‐cost, and solution‐processed flexible optoelectronic devices. This review introduces the limitations of anode buffer layers based on conducting polymers and then we will provide recent research trends of material engineering to overcome these problems.

“…However, utilization of the bare glassy carbon electrode (GCE) has drawbacks that include low response, fouling, and low sensitivity. Consequently, chemically modified electrodes have been widely examined, including the use of carbon nanotubes (Luo et al 2008), gold nanoparticles (Chu, Han, and Zhang 2011), Fe2O3 , polymers ), composites , Fan et al 2011, Roy et al 2013, mobile crystalline material-41 (Thatshanamoorthy et al 2014), and hydroxyapatite (Mhammedi et al 2009). However, these materials have limitations that include low yield of the product, difficult preparation, high cost, low sensitivity, and poor precision.…”

A para-nitrophenol sensor based on a 5-sulfosalicylic acid doped polyaniline nanorods modified glassy carbon electrode is reported. The formation of 5-sulfosalicylic acid doped polyaniline was characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The electroactivity of the 5-sulfosalicylic acid doped polyaniline nanorods was studied by cyclic voltammetry and differential pulse voltammetry and high response was observed for the reduction of para-nitrophenol. The calibration curve for para-nitrophenol was linear from 6.7 × 10 6 M to 112.1 × 10 6 M. The sensitivity and limit of detection were 24 nA µM 1 and 3.2 × 10 6 M, respectively. The sensor was simple, inexpensive, and employed for the determination of para-nitrophenol in tap water with recoveries from 97.6 to 101.0%.
