Poly(phenoxy-imine)s and Poly(phenoxy-ketimine)s: Toward New Semiconductive Polymeric Materials

Abstract

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.
