Synthesis, characterization, and electrochromic properties of conducting poly(hexanedioic acid bis-(2-thiophen-3-yl-ethyl ester) and its copolymer with thiophene

2004-10-14
Hexanedioic acid bis-(2-thiophen-3-yl-ethyl) ester (HABTE) was synthesized via the reaction of 3-thiophene ethanol with adipoyl chloride. Resulting monomer was electrochemically homopolymerized in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, in acetonitrile/borontrifloride ethylether solvent mixture (8:2, v/v). Copolymerization in the presence of thiophene was achieved in TBAFB/AN. Resulting homo and copolymers were characterized via CV, FTIR, DSC, TGA, SEM, and UV-vis Spectroscopy. Spectroelectrochemistry analysis of homopolymer, P(HABTE), reflected electronic transitions at 385, 600, and 900 nm, revealing pi-pi* transition, polaron, and bipolaron band formation, respectively. Switching ability of the homopolymer was evaluated by a kinetic study upon measuring the %T at the maximum contrast point, indicating that PHABTE is a potential material for electrochromic devices.

A new dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and butanedioyl dichloride. Electrochemical behavior of this monomer, succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) was studied. Homopolymerization was achieved by chemical and constant Current electrolysis methods. Copolymerization of SM with thiophene was performed by constant potential electrolysis in acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) and dichloromethane (DCM)-TBAFB, solvent-electroly...

A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(perfluorophenyl)-2,5-di(2-thienyl)-1H-pyrrole (FPTPy). The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1-NMR) and fourier transform infrared (FTIR). Polymer of FPTPy was also synthesized via potentiostatic electrochemical polymerization in acetonitrile (AN)/NaClO4/LiClO4 (0.1 M:0.1 M) Solvent-electrolyte couple. Characterizations of th...

Poly(2-(N-pyrrolyl)ethylvinylether) (poly(2-NEVE)) was synthesized from poly(2-chloroethylvinylether) (poly(2-CEVE)) via phase catalysis reaction. Graft copolymers of PPy/poly(2-NEVE) were synthesized by electrochemical methods. The chemical structure of poly(2-NEVE) was investigated by several spectroscopic and thermal methods. Graft copolymers were characterized by means of FTIR, Differential Scanning Calorimetry (DSC), Thermal Gravimetry Analysis (TGA), Scanning Electron Microscope (SEM). Conductivities ...

Zinc borate was synthesized from the reaction of zinc oxide and boric acid in the absence or presence of seven different water soluble additives. Additive concentration and zinc oxide particle size were varied to investigate their effect on the growth kinetics of zinc borate particles. Zinc borate particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Samples taken from the reaction mixture during the synthesis were analyzed for dete...
Synthesis of a regular polymer containing pseudo-polyether cages
Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2005-04-20)
A new compound consisting of 2-thienyl units linked by polyether bridge has been synthesized and its electrochemical polymerization was performed via constant potential electrolysis (CPE) in an electrolytic solution containing 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)) dissolved in CH3CN. Chemical polymerization was carried out using FeCl3 as oxidizing agent. It is found that both methods gave the same polymer product without any cleavage of the polyether bridge between thiophene (Th) rings. Al...
