“…[1][2][3] One class of these polymers is polyphenols, which contain active hydroxyl (-OH) groups that are synthesized by enzymatic polymerization 4,5 or oxidative polycondensation methods. 6,7 Oxidative polycondensation is advantageous in that this process can offer simple and mild reaction conditions when compared with other methods. Many researchers have been trying to improve the properties of polyphenols by adding functional groups to their structures.…”

The chemical synthesis of a new type of polyphenol was achieved by oxidative polycondensation of 4-((2-phenylhydrazono)methyl) phenol (4-PHMP). The polymerization of 4-PHMP was performed using sodium hypochlorite and air (O 2 ) as oxidizing agents in an aqueous alkaline medium under various polymerization conditions. The molecular weight of the polymer was determined by gel permeation chromatography, and the polymeric structure was characterized by elemental analysis, ultraviolet-visible, Fourier transform infrared and nuclear magnetic resonance techniques. In addition, thermal and electrochemical properties of the synthesized compounds were investigated. According to electrochemical measurements, the polymer had a low band gap (E g 0 ¼ 1.52 eV) and appeared to be an interesting candidate for solar-cell 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.

The oxidative polycondensation of 2-methylquinolin-8-ol (2-MQ) has been accomplished by using H 2 O 2 oxidant in aqueous alkaline medium. Optimum reaction conditions of the oxidative polycondensation and the main parameters of the process were established. At optimum reaction conditions, yield of the products was found to be 32.0%. The structures of the obtained monomer and oligomer were confirmed by FT-IR, UV-vis, 1 H-NMR, 13 C-NMR and elemental analysis. The characterization was made by TG-DTA, using size exclusion chromatography (SEC) and solubility tests. The FT-IR, 1 H-NMR and 13 C-NMR data shows that the polymerization proceeded by the C-C coupling of ortho and para positions according to -OH group of 2-MQ. The molecular weight distribution values of the product were determined by SEC. The number-average molecular weight (M n ), weight-average molecular weight (M w ) and polydispersity index (PDI) values of O-2-MQ were found to be 1980, 3312 and 1.681 for H 2 O 2 oxidants, respectively. Thermal analysis results of O-2-MQ demonstrated to be stability against thermal decomposition. Thermal analyses of 2-MQ-Cd, 2-MQ-Co, 2-MQ-Cu, 2-MQ-Zn, O-2-MQ-Cd, O-2-MQ-Co, O-2-MQ-Cu, and O-2-MQ-Zn monomer/oligomer-metal complex compounds were investigated in a N 2 atmosphere between 15 -10008C.
