Here we report the preparation of two solution processible polymers; poly(2-(5-(2-(2-octyldodecyl)-2H-benzo[d][1,2,3]triazol-4-yl)thiophen-2-yl)-5-(thiophen-2-yl)thiazolo[5,4-d]thiazole) (PBTTz) and poly(2-(5-(9,9-dioctyl-9H-fluoren-2-yl)thiophen-2-yl)-5-(thiophen-2-yl)thiazolo[5,4-d]thiazole) (PFTTz) which are multichromic electroactive polymers. PBTTz was synthesized via Stille coupling polymerization whereas PFTTz was synthesized via Suzuki coupling polymerization. Both polymers were coated on ITO slides and their electrochromic properties were investigated. The results of the PBTTz were also compared with a previously published polymer to investigate the linear and branched alkyl chain effect. The polymers were compared through their optical properties and UV-Vis spectroelectrochemistry.

Electrochemical synthesis of crowned conducting polymers : nature of radical cations in polymerization and mechanism of conductivity Cihaner, Atilla; Önal, Ahmet Muhtar; Department of Chemistry (2004) Poly(dibenzo-18-crown-6) (Poly(DB18C6)) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as solvent and tetrabutylammonium tetrafluoroborate (TBABF4) or tetrabutylammonium hexafluorophosphate (TBAPF6) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in-situ ESR and in-situ UV-VIS spectroscopic techniques. Spectroelectrochemical (SPEL) properties and thermal analysis of the resulting polymers h...
Pyrolysis mass spectrometry analysis of electrochemically grafted polyacrylonitrile with thiophene Oguz, Gulcan; Hacaloğlu, Jale; Önal, Ahmet Muhtar (2005-10-01) In this work, structural and thermal analyses of a polythiophene/polyacrylonitrile (PTh/PAN) sample, prepared by electrochemical polymerization of thiophene onto a poly(acrylonitrile) coated anode, have been performed by a direct insertion probe pyrolysis mass spectrometry technique. The evolution profiles of PTh based products from PTh/PAN showed nearly identical trends with those recorded during the pyrolysis of pure PTh. However, when PAN based products were considered, contrary to the trends observed fo...
Chain-extended bismaleimides .1. Preparation and characterization of maleimide-terminated resins Yerlikaya, Z; Oktem, Z; Bayramlı, Erdal (1996-01-03) Starting from aromatic diamines, a series of bismaleimides (BMIs) and maleimide-terminated structural resins were prepared in solution and characterized. Maleimide-terminated resins were prepared through Michael addition reaction with 3/2 molar ratio of bismaleimide and aromatic diamine as reactants. The structural analysis was performed by FTIR and H-1-NMR spectroscopy. Thermal properties are investigated by TGA, DTA, and DSC. Number-average molecular-weights of the resins were determined by cryoscopy. The...
Photovoltaic properties of benzotriazole containing alternating donor–acceptor copolymers: Effect of alkyl chain length Baran, Derya; Balan, Abidin; Stubhan, Tobias; Ameri, Tayebeh; Toppare, Levent Kamil; Brabec, Christoph J. (Elsevier BV, 2012-12) A series of variable alkyl chain length substituted donor-acceptor (D-A) conjugated polymers with thiophene ring as the donor and benzotriazole moiety as the acceptor has been investigated in bulk heterojunction solar cells. The optical and electrochemical properties showed that the absorption onsets and the energy levels of the copolymers were not affected by alkyl substitution revealing 1.9 eV of optical band gap. The morphologies of the blend film can be fine-tuned by increasing the chain length attached...
Novel poly(2,5-dithienylpyrrole) (PSNS) derivatives functionalized with azobenzene, coumarin and fluorescein chromophore units: spectroelectrochemical properties and electrochromic device applications Yigit, Deniz; Hacioglu, Serife O.; GÜLLÜ, Mustafa; Toppare, Levent Kamil (2015-01-01) Three novel 2,5-dithienylpyrrole (SNS) derivatives containing strong chromophore units such as azobenzene, coumarin and fluorescein were synthesized to investigate the effects of chromophore substituents on the electrochemical and spectroelectrochemical properties of resulting polymers. Electrochemical and optoelectronic characteristics of the homopolymers, poly(1-(2-(4-(phenyldiazenyl)phenoxy)ethyl)-2,5di(thiophen-2-yl)-1H-pyrrole) (PTPTAz), poly(4-(2-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)ethoxy)-2H-chrome...
