A novel series of hybrid monomers containing furan and fluorene units, namely 2-(2-(furan-2-yl)-9H-fluoren-7-yl)furan (FFF), 2,7-di(furan-2-yl)-9H-fluoren-9-one (FOF) and 2-(2-(furan-2-yl)-9,9-dihexyl-9H-fluoren-7-yl)furan (FHF), was synthesized and their electrochemical polymerization was achieved via potential cycling. Optical and electrochemical properties of the polymers, poly(2-(2-(furan-2-yl)9H-fluoren-7-yl)furan (PFFF), poly(2,7-di(furan-2-yl)-9H-fluoren-9-one) (PFOF) and poly(2-(2-(furan2-yl)-9,9-dihexyl-9H-fluoren-7-yl)furan) (PFHF), were investigated and it was found that polymer films exhibited quasi-reversible redox behavior (E-p(ox) =0.92V for PFFF, E-p(ox) = 1.08V for PFOF and E-p(ox) = 0.99V for PFHF) accompanied with a reversible electrochromic behavior, yellow to dark blue for PFFF, orange to green for PFOF and orange to green for PFHF. Their band gap values (E-g) were found to be 2.49, 2.32 and 2.61 eV for PFFF, PFOF and PFHF, respectively.

Synthesis of conducting block copolymers and their use in the immobilization of invertase and polyphenol oxidase enzyme
Kıralp, Senem; Kıralp, Senem; Department of Chemistry (2004)
A new thiophene derivative containing menthyl group (MM) was synthesized and polymerized via chemical and electrochemical methods. Polymers obtained and MM itself were used to synthesize copolymers with pyrrole under conditions of constant potential electrolysis. Cyclic Voltammetry, thermal analysis and scanning electron microscopy analyses were performed for the characterization of samples. Immobilization of invertase and polyphenol oxidase enzymes was performed in the matrices obtained via copolymerizatio...
Synthesis and characterization of thiophene functionalized polystyrene copolymers and their electrochemical properties
Sahin, E; Camurlu, P; Toppare, Levent Kamil; Mercore, VM; Cianga, I; Yagci, Y (Wiley, 2005-12-01)
Thiophene functionalized polystyrene samples (TFPS) were synthesized by atom transfer radical polymerization (ATRP) of styrene, followed by Suzuki coupling with 3-thiophene (Th) boronic acid. Conducting graft polymer of TFPS with thiophene was achieved at 1.5 V in tetrabutylammonium tetrafluoroborate/dichloromethane (TBAFB/DM) by electrochemical methods. Spectroelectrochemical analysis of the resulting copolymers [P(TFPS-co-Th)] reflected electronic transitions at 449, 721 and 880 nm, revealing pi - pi* tra...
Synthesis and polymerization of new D-A-D type monomers bearing fluorinated benzothiadiazole acceptors and their optoelectronic applications
Boztaş, Yalçın; Önal, Ahmet Muhtar; Department of Chemistry (2022-5-11)
In this study, a new series of alkylenedioxythiophene (ProDOT) type monomers bearing substituted and unsubstituted benzothiadiazole acceptor units was synthesized, and the resulting derivatives were characterized by using NMR spectroscopy, elemental analysis and HRMS techniques. The monomers were polymerized by electrochemical polymerization method. The electrochemical and optical properties of monomers and their corresponding polymers were thoroughly investigated in detail to elucidate how the number of fl...
Synthesis and electrochemical properties of a new benzimidazole derivative as the acceptor unit in donor-acceptor-donor type polymers
OZELCAGLAYAN, Ali Can; SENDUR, Merve; AKBASOGLU, Naime; APAYDIN, Dogukan Hazar; Çırpan, Ali; Toppare, Levent Kamil (2012-04-15)
A new benzimidazole unit, 4'-(tert-butyl)spiro[benzo[d]imidazole-2,1'-cyclohexane] was synthesized and coupled with different donor units like 3-hexylthiophene and 3,4-ethylenedioxythiophene (EDOT) via Stille coupling. The donor-acceptor-donor (D-A-D) type monomers, 4'-(tert-butyl)-4,7-bis(4-hexylthiophen-2-yl)spiro[benzo[d]imidazole-2,1'-cyclohexane] (BIHT) and 4'-(tert-butyl)-4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)spiro[benzo[d]imidazole-2,1'-cyclohexane] (BIED) were electrochemically polymerize...
Synthesis and characterization of a polybenzoxazine from a difunctional amine and a trifunctional phenol
Kaya, Şafak; Tinçer, Teoman; Department of Polymer Science and Technology (2009)
Synthesis of a polymer with benzoxazine units in the main chain backbone by a trifunctional phenol, a difunctional amine, and paraformaldehyde was achieved. Thermal, mechanical and spectroscopic characterization and the viscosity properties of the synthesized polymer were studied. In the first step of this study, a fast and feasible method for the synthesis of the benzoxazine precursors was developed since some methods mentioned in the literature about the synthesis of the benzoxazine derivatives last long ...
