New electroluminescent cyano-substituted phenylenevinylene (PV) monomeric and oligomeric chromophores, 1–3, were synthesized by Knoevenagel condensation and investigated in terms of their photoluminescence (PL) and electroluminescence (EL) behavior. All show PL emission maxima between 463 and 471 nm in solution with quantum efficiencies of 0.65, 0.46 and 0.68, respectively. EL maxima in an LED configuration ITO/PEDOT–PSS/1–3/Ca–Al were 507, 518 and 551 nm with luminance efficiencies 0.01, 0.05 and 0.02 cd/A, respectively.

Both anodically and cathodically coloring electrochromic polymer based on dithieno[3,4-b,3 ',4 '-e]-[1,4]-dithiine
Sahin, E; Camurlu, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01)
In this study poly(dithieno[3,4-b,3',4'-e]-[1,4]-dithiine) (PDTH) was synthesized potentiodynamically in both p- and n-doping domains in 0.1 M tetrabutylammonium tetrafluoroborate/acetonitrie/borontrifluoride ethylether (8:2, v/v). Resulting homopolymer was characterized via cyclic voltammetry, FTIR and UV-vis Spectroscopy. PDTH revealed both anodically and cathodically coloring electrochromic behavior, upon p-and n-doping, respectively. Spectroelectrochemistry analysis of p-doped polymer, reflected electro...
Synthesis of New Thienylene Pyrrole Monomers and Their Electropolymerizations
Eken, Serap; Carbas, Buket Bezgin; Akdağ, Akın; Önal, Ahmet Muhtar (The Electrochemical Society, 2014-01-01)
In this study, four new 2,5-dithienylpyrroles (SNS) 1-(3-fluoro-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-FPTP), 1-(3-chlorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-ClPTP), 1-(3-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-BrPTP) and 1-(4-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (p-BrPTP) containing meta and para substituted benzene ring at the nitrogen atom were synthesized via Paal-Knorr condensation of 1,4-di(2-thienyl)-1,4-butanedione with corresponding halo-substituted anilines. The mon...
A CONDUCTING COMPOSITE OF POLYPYRROLE .1. SYNTHESIS AND CHARACTERIZATION
SELAMPINAR, F; Akbulut, Ural; YALCIN, T; SUZER, S; Toppare, Levent Kamil (Elsevier BV, 1994-02-01)
A conducting composite of polypyrrole was prepared via electrochemical methods. A polyamide was used as the insulating matrix polymer. The characterization of the composite was done by FT-IR, SEM, TGA, DSC and pyrolysis studies. Conductivity and solubility studies together with spectroscopic methods reveal that H bonding exists between the two polymers and a possible grafting to a certain extent.
THE INFLUENCE OF WATER ON THE ELECTROCHEMICAL POLYMERIZATION OF 3-ACYLPYRROLES
VOIGT, M; ROHDE, N; HALLENSLEBEN, ML; Toppare, Levent Kamil (Elsevier BV, 1993-03-22)
Several poly(3-acylpyrrole)s have been studied by cyclic voltammetry. The influence of some common impurities like water and cyanide present in the solvent-electrolyte system on the redox behavior of the polymer films were emphasized. Due to the presence of such impurities we have also observed changes in the macroscopic properties of the films such as their electrical conductivities. There is enough evidence that the amount of such impurities can be correlated to the degree of the so called overoxidation p...
DERIVATIVES OF POLY(PYRROLE) WITH DECONJUGATED CARBONYL SUBSTITUENTS IN BETA-POSITION
VOIGT, M; GEISSLER, U; HAASE, V; VOIGT, B; HALLENSLEBEN, ML; Toppare, Levent Kamil (Elsevier BV, 1993-03-22)
Four omega-(3-pyrrolyl)esters were investigated by cyclic voltammetry, electron microscopy and conductivity measurements. The corresponding poly(pyrrole) derivatives exhibit enhanced conductivities compared to poly(3-acylpyrrole)s, and their electrochemical behavior resembles that of poly(3-alkylpyrrole)s rather than the poly(3-acylpyrrole) derivatives. Ester saponification occurring during electropolymerization was examined by gas chromatography.
