“…5a shows the changes in the absorption spectrum of P(B1) in an AN/LiClO 4 solution under various applied potentials. As the polymer devices oxidized, the intensities of their p-p* transitions decreased, and their charge carrier bands at approximately 800-900 nm increased because of polaron formation [39]. However, in this study any p-p* The p-p* transitions related to P(B1) was observed at 320 nm, and also polaron and bipolaron band formations at 400 nm and 670 nm, respectively.…”

“…For P(B1) maximum contrast (%T) and switching time were measured from Fig. 6 as 43% and 4 s for 670 nm by stepping the potential between 0.0 and +1.2 V with a residence time of 5 s. The stability of the redox states during the scans is the most property for an electro-active polymer to be useful in constructing new electrochromic devices [32,33,35,39,48]. Additionally, the ability of a material to exhibit a noteworthy color change is important for electrochromic applications.…”

Conjugated polymers have attracted widespread interest during the last three decades, because of their useful electronic properties. In this paper we discuss semi-conductive properties of the conjugated polymers with phenylhydrazono (C 6 H 5 -NH-N=C-(R/H)-) pendent groups, such as poly(phenoxy-imine)s and poly(phenoxy-ketimine)s. These polymers were found to possess the conductivity of 10 -3 -10 -2 S/cm. It is supposed that high conductivities of the polymers are due to their phenylhydrazono type structures with π-conjugation with participation of the nitrogen atoms in polymer side groups.Keywords: Conjugated polymers; Semi-conductive polymer; Poly(phenoxy-imine) s; Poly(phenoxy-ketimine)s; Oxidative coupling polymerization; Gel permeation chromatography Poly(phenoxy-imine)s and Poly(phenoxy-ketimine)s: Toward New Semiconductive Polymeric Materials 2/6Copyright: ©2017 Demir literature (As can be seen in Supplementary Information, (Table 1-3). They can be seen that the highest conductivity values belong to poly(4-PHMP) and poly(3-PHEP). This is because of the polyconjugated structures of the polymers with phenylhydrazono pendent groups that increase electrical conductivity values. Having this feature, these polyphenols step forwards in comparison with other imine-substituted polyphenols. The results obtained in this study are compatible with the values in literature. *: These data demostrated the maximum (or saturated) conductivity after iodine doping. 2/6 Poly(phenoxy-imine)s and Poly(phenoxy-ketimine)s: Toward New Semiconductive Polymeric Materials 5/6Copyright: ©2017 Demir Further work is being carried out in our laboratory to synthesis and characterization of other polyphenols containing phenylhydrazono pendent groups and to investigation of their properties such as conductivity and some properties. These results will be published soon in a full paper. AcknowledgementThe author thanks Dr. Ilkay Ozaytekin for measuring the electrical conductivity. Conflict of InterestNone.

Synthesis and electrochromic properties of epoxy materials containing triphenylamine units

et al. 2015

A series of novel aromatic epoxy resins are prepared from the epichlorohydrin (ECH) and di(4-hydroxybenzylideneamino) triphenylamine (DHB-TPA) monomers, which are synthesized from different triphenylamine (TPA)-containing diamines and phydroxybenzaldehyde. FT-IR, 1 H NMR and UV-Vis absorption spectra are employed to characterize the chemical structures of the polymers. All the polymers are amorphous, soluble in a variety of common organic solvents. The thermal properties of the polymers are investigated by thermogravimetric analysis (TGA) indicating good thermal stabilities compared with conventional epoxy resins on behalf of the introduction of aromatic TPA groups. All the polymers exhibit excellent reversibility of electrochromic characteristics by continuous cyclic scans between 0 and 2.0 V with the color changing from green to blue. The polymers also display photoelectrical response. The above properties prove that the series of polymers exhibit high thermal stability, excellent reversibility of electrochromic characteristics and photoelectric behaviours, which can be prospective candidates as electrochromic materials and photoelectrical conversion materials.
