Polymerization of new aniline derivatives: synthesis, characterization and application as sensors

Abstract

This work is focused on modifying aniline monomers with various characteristics that allows one to study the effect of the substituent on the respective polymer.

Earth-abundant and environmentally benign Ni–Zn iron oxide intercalated in a polyaniline based nanohybrid as an ultrafast photodetector

“…This shows the degree of electron delocalization as well as the material's electrical conductivity. 55 Furthermore, the presence of a benzene ring is compatible with the bands corresponding to the out-of-plane deformation vibrations of C-H bonds in the range of 800-700 cm −1 . 55 The region below 1000 cm −1 represents the vibrations between the ions present in the crystal lattices and the spinel structure of NZF, giving two prominent metal-oxygen (M-O) absorption bands.…”

“…The deconvolution of the N 1s core-level spectrum yielded two large peaks at 399.10 and 401.60 eV, which represent the imine and amine groups, respectively. 55 As shown in Fig. 4g, there are strong peaks for –N, –N+, and N–H with binding energies of 399.86, 401.28, and 401.98 eV, respectively.…”

“…48,50 The oxidation state of Fe was 3+ due to the satellite features of Fe 2p. 48,50 [52][53][54][55] The sp 2 (CvC) peak of the NZF-PANI nanohybrid was noticeably more intense, which could be due to the polyaniline expanded-conjugation network. The deconvolution of the N 1s core-level spectrum yielded two large peaks at 399.10 and 401.60 eV, which represent the imine and amine groups, respectively.…”

“…4g, there are strong peaks for -Nv, -N+, and N-H with binding energies of 399.86, 401.28, and 401.98 eV, respectively. 52,55 The presence of sulfur is also seen due to the APS and p-TSA used in the polymerization of PANI. 52,56 The peak positions of sulfur with binding energies of 168-169 eV for the sulfate group and 170.02 eV for thiosulphates are shown in Fig.…”
