Poly(2,5-di-(2-thienyl)-furan) (PSOS) was synthesized via anodic polymerization of 2,5-di-(2-thienyl)-furan (SOS) in ethanol solution containing 0.2 M LiClO4 as supporting electrolyte. The electrochemical and spectroelectrochemical properties were investigated using electroanalytical and UV-vis spectroscopic techniques, respectively. The band gap of the polymer film was found as 2.22 eV and the film was successfully switched between black oxidized state and orange neutral state. Fluorescence and electrochemical impedance spectroscopy (EIS) studies were also performed.

Spectroelectrochemical investigation of the anodic oxidation of dibenzo-18-crown-6
Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2004-10-01)
Poly(dibenzo-18-crown-6) (poly-DB18C6) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as the solvent and tetrabutylammonium tetrafluoroborate (TBABF(4)) or tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in situ ESR and in situ UV-Vis spectroscopic techniques. Spectroelectrochemical (SPEL), properties and thermal analysis of the resulting po...
Electrochemical copolymerization and characterization of dianilines linked by polyether bridge with aniline
TİRKEŞ, SEHA; Önal, Ahmet Muhtar (Springer Science and Business Media LLC, 2010-04-01)
Copolymer of aniline and triethylene glycol bis(o-aminophenyl) ether was synthesized by constant potential electrolysis. Cyclic voltammogram of the copolymer films recorded in the monomer-free electrolytic solution revealed that the redox behavior of the films approaches to that of poly(triethylene glycol bis(o-aminophenyl) ether) with increasing amount of triethylene glycol bis(o-aminophenyl) in the feed ratio. Copolymerization was investigated by in situ recording the changes in the electronic absorption ...
Syntheses of electroactive layers based on functionalized anthracene for electrochromic applications
Yıldırım, Ahmet; Tarkuc, S.; AK, MESUT; Toppare, Levent Kamil (Elsevier BV, 2008-05-30)
A new monomer (DTAT) was synthesized via linking 3,4-ethylenedioxythiophene (EDOT) on anthracene. The polymer, P(DTAT) was electrosynthesized by anodic oxidation of the corresponding monomer in 0.1 M LiClO4 acetonitrile (ACN) solution. The optical properties, the absorption spectra and the kinetics, were examined. Spectroelectrochemical analysis showed that P(DTAT) has an electronic band gap (due to pi-pi* transition) of 1.57 eV at 776 nm.
Surfactant modified zinc borate synthesis and its effect on the properties of PET
Baltaci, Berk; ÇAKAL, GAYE ÖZGÜR; Bayram, Göknur; Eroglu, Inci; Özkar, Saim (Elsevier BV, 2013-08-01)
Zinc borate was prepared from the reaction of zinc oxide and boric acid in the absence or presence of cumene terminated poly(styrene-co-maleic anhydride), PSMA, added as a surfactant at varying concentrations (0.1-1 wt.% of water) to the reaction medium to investigate its effect on the growth and agglomeration of particles during reaction. Synthesized zinc borates were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) in comparison to unmodifie...
Polystyrene-b-poly(2-vinyl phenacyl pyridinium) salts as photoinitiators for free radical and cationic polymerizations and their photoinduced molecular associations
Taskin, Omer Suat; Erel Göktepe, İrem; Khan, Muhammad Alyaan Ahmed; Pispas, Stergios; Yağcı, Yusuf (Elsevier BV, 2014-07-01)
Polystyrene-b-poly(2-vinyl phenacyl pyridinium hexafluorophosphate) (PS-b-PVPP) was synthesized by reacting polystyrene-b-poly(2-vinyl pyridine) prepared by living anionic polymerization with phenacyl bromide followed by counter anion exchange reaction. The ability of PS-b-PVPP to act as a photoinitiator for both free radical and cationic polymerizations is demonstrated. In the free radical polymerization, the initiation step involves the decay of the excited state of the salt with homolytic bond rupture of...
