Two new furan and benzochalcogenodiazole based monomers, namely 4,7-di(furan-2-yl) benzo[c][1,2,5]-selenadiazole (FSeF) and 4,7-di(furan-2-yl) benzo[c][1,2,5]thiadiazole (FSF), were designed and synthesized via a donor-acceptor-donor approach. The monomers were electrochemically polymerized via potentiodynamic or potentiostatic methods. The monomers and their polymers exhibited lower oxidation potentials (1.16 V and 1.06 V for monomers; 0.93 V and 0.80 V for polymers vs. Ag/AgCl) and red shifts of the whole dual-band absorption spectra upon moving from S to Se. Intramolecular charge transfer properties of the monomers and the polymers were demonstrated by using electroanalytical and optical methods. Also, the polymers PFSeF and PFSF were multicolored at different redox states and have low band gaps of 1.43 eV and 1.61 eV, respectively.

A novel multielectrochromic copolymer based on 1-(4-nitrophenyl)-2,5-di(2-thienyl)-1H-pyrrole and EDOT Varis, Serhat; Ak, Metin; Akhmedov, Iris M.; Tanyeli, Cihangir; Toppare, Levent Kamil (2007-05-01) Copolymer of 1-(4-nitrophenyl)-2,5-di(2-thienyl)-1H-pyrrole (NTP) with 3,4-ethylene dioxythiophene (EDOT) was electrochemically synthesized and characterized. Resulting copolymer film has distinct electrochromic properties. It has five different colors (light red, red, light grey, green, and blue). At the neutral state lambda(max) x value due to the pi-pi* transition was found to be 550 nm and E-g was calculated as 1.6 eV. Double potential step chronoamperometry experiment shows that copolymer film has good...
Alkyl-end phenanthroimidazole modification of benzotriazole based conjugated polymers for optoelectronic applications Cevher, Şevki Can; Keles, Duygu; Hızalan, Gonul; Toppare, Levent Kamil; Çırpan, Ali (2018-10-01) A new triazoloquinoxaline and benzodithiophene based copolymer was synthesized to investigate its electrochemical, optical and photovoltaic behaviors. According to the polymer design, combination of two acceptor units (benzotriazole and quinoxaline) which contribute imine bonds to the structure and a triazoloquinoxaline unit for enhancing electron accepting ability was pursued. As a result of electrochemical studies, the copolymer PTQBDT has a low lying HOMO energy level as −5.23 eV which increases the chem...
Efficient benzodithiophene and thienopyrroledione containing random polymers as components for organic solar cells Azeri, Ozge; Aktas, Ece; Istanbulluoglu, Cagla; Hacioglu, Serife O.; CEVHER, ŞEVKİ CAN; Toppare, Levent Kamil; Çırpan, Ali (2017-12-20) Benzodithiophene and thienopyrroledione containing two random copolymers were designed and synthesized. Electrochemical and optical studies prove that these copolymers could be candidates for organic solar cells applications. The HOMO and LUMO values were determined using cyclic voltammetry as -5.53 and -3.43 eV for P1 and -5.54 and -3.53 eV for P2, respectively. The optical band gaps of the polymers were calculated as 2.10 and 2.01 eV using UV-VIS spectroscopy for P1 and P2, correspondingly. Bulk-heterojun...

Conducting graft copolymers of pyrrole and thiophene with random copolymers of methyl methacrylate and 3-methylthienyl methacrylate Guner, Y; Toppare, Levent Kamil; Hepuzer, Y; Yagci, Y (2004-08-01) Random copolymers of 3-methyl thienylmethacrylate and methyl methacrylate were synthesized via free radical polymerization. Electro-copolymerizations of random copolymers with thiophene and/or pyrrole were carried out in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB), water-p-toluene sulfonic acid (PTSA) solvent-electrolyte couples. Oxidative polymerization of thiophene functionalized random copolymer was also achieved by constant current electrolysis and chemical polymerization. The characteriza...
