Copolymer of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) with N-methylpyrrole (NMPy) was synthesized by potentiostatic electrochemical polymerization in acetotiitrile-tetrabutylammonium tetrafluoroborate solvent-electrolyte couple. The chemical structures were confirmed via Fourier transform infrared spectroscopy (FTIR), cyclic voltammetry (CV), and UV-vis spectroscopy. Electrochromic and spectroelectrochemical properties of poly(TAPE-co-NMPy) [P(TAPE-co-NMPy)] were investigated. Results showed that the copolymer revealed color change between light yellow and green upon doping and dedoping of the copolymer, with a moderate switching time. Furthermore, as an application, dual-type absorptive/transmissive polymer electrochromic device (ECD) based on poly(TAPE-co-NMPy) and poly (3,4-ethylene dioxythiophene) (PEDOT) have been assembled, where spectroelectrochemistry, switching ability, stability, and optical memory of the ECD were investigated. Results showed that the device exhibited good optical memory and stability with moderate switching time. (c) 2006 Wiley Periodicals, Inc.

BINGÖL, Bahar; GÜNER, Yusuf; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2005-08-01)
Thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) monomer was synthesized via reaction of thiophen-3-yl acetyl chloride with 4-pyrrol-1-yl phenol. Homopolymers were achieved by using electrochemical and chemical polymerization techniques. Copolymers of TAPE with bithiophene or pyrrole were synthesized by potentiostatic electrochemical polymerization in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couple. The chemical structures were confirmed by both Nuclear Magnet...

A new polythiophene derivative was synthesized by electrochemical oxidative polymerization of 2,5-di( thiophen-2-yl)-1-(4-(thiophen-3-yl) phenyl)-1H-pyrrole (TTPP). The structure of the monomer was evaluated by H-1-NMR and FT-IR. The polymer (P(TTPP)) and its co-polymer with 3,4-ethylenedioxythiophene (P(TTPP-co-EDOT)) were synthesized via potentiostatic electrochemical polymerization. The resulting polymers were characterized by cyclic voltammetry (CV), FT-IR, SEM and UV-Vis spectroscopy, and conductivity ...
Synthesis and characterization of fully aromatic thermotropic liquid-crystalline copolyesters containing m-hydroxybenzoic acid units
Yerlikaya, Z; Aksoy, S; Bayramlı, Erdal (Wiley, 2001-10-01)
A series of fully aromatic copolyesters based on p-acetoxybenzoic acid (p-ABA), hydroquinone diacetate (HQDA), terephthalic acid (TPA), and m-acetoxybenzoic acid (m-ABA) were prepared by a modified melt-polycondensation reaction. The copolyesters were characterized by DSC, thermogravimetric analysis, H-1 NMR, polarized optical microscopy, X-ray diffraction, and intrinsic viscosity measurements. The copolyesters exhibited nematic liquid-crystalline phases in a broad temperature range of about 150 degreesC, w...

New pi-conjugated polymers containing dithieno(3,2-b: 2',3'-d) pyrrole (DTP) were successfully synthesized via electropolymerization. The effect of structural differences on the electrochemical and optoelectronic properties of the 4-[4H-dithieno(3,2-b: 2',3'-d) pyrrol-4-yl] aniline (DTP-aryl-NH2), 10-[4H-dithiyeno(3,2-b: 2',3'-d) pirol-4-il] dekan-1-amine (DTP-alkyl-NH2), and 1,10-bis[4H-dithieno(3,2-b:2',3'-d) pyrrol-4-yl] decane (DTP-alkyl-DTP) were investigated. The corresponding polymers were characteri...
TRANSPORT OF SODIUM-CHLORIDE, UREA, AND CREATININE THROUGH MEMBRANES DERIVED FROM METHYLMETHACRYLATE-CO-METHACRYLIC ACID AND ITS IONOMERS
BDAIR, A; ARAS, L; SANLI, O (Wiley, 1993-02-20)
Permeabilities of cast films of methylmethacrylate-co-methacrylic acid (MMA-MAA) and its 5% neutralized Na1+, Cs1+, Zn2+, Ba2+, and Al3+ ionomers for urea, sodium chloride, and creatinine were determined using a double (donor and acceptor) compartment cell. Film permeability was increased as the ionic potential decreased and it was more marked with urea as compared with sodium chloride and creatinine. Tensile properties of the above samples were also tested and variations in Young's Moduli were based on the...
