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.

Synthesis of a new monomer, 2,5-bis-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1-phenyl-1H-pyrrole (ENE), from pyrrole, iodobenzene and 3,4-ethylenedioxythiophene (EDOT), and its electropolymerization are reported. ENE was oxidized at a low oxidation potential (0.45 V vs. Ag/AgCl) and successfully electropolymerized in acetonitrile containing 0.1 M NaClO4 and LiClO4 electrolyte mixture. The resulting polymer, P(ENE), revealed five distinctive colors upon doping, which indicated that the polymer is multichro...
Multichromic polymers of benzotriazole derivatives: Effect of benzyl substitution
Yigitsoy, Basak; Karim, S. M. Abdul; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2011-02-01)
Two electroactive monomers 1-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTA) and 2-benzyl-4,7-di(thiophen-2-yl))-2H-benzo[d][1,2,3]triazole (BBTS) were synthesized with satisfactory yields. The effect of substitution site on electrochemical and optical properties was investigated with cyclic voltammetry and spectroelectrochemical studies. Results showed that position of pendant group alters the electronic structure of the resulting polymer causing different optical and electrochemical behavi...

Icli, Merve; Cihaner, Atilla; Oenal, Ahmet A. (Elsevier BV, 2007-11-01)
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 electrochem...
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 ...
Synthesis and spectroelectrochemical characterization of multi-colored novel poly(3,6-dithienylcarbazole) derivatives containing azobenzene and coumarin chromophore units
Yigit, Deniz; Hacioglu, Serife O.; GÜLLÜ, Mustafa; Toppare, Levent Kamil (Elsevier BV, 2016-04-01)
Azobenzene and coumarin units bearing four novel 3,6-linked thiophene-carbazole-thiophene type electroactive monomers were synthesized in order to observe the effects of strong chromophore units on the electrochemical and spectroelectrochemical behaviors of resulting pi-conjugated conducting polymers (PTCbzAz, PECbzAz, PTCbzCo and PECbzCo). Electronic and optoelectronic properties of all polymers were investigated by cyclic voltammetry and in situ spectroelectrochemical studies, and their oxidation potentia...
