In this report, we highlight the synthesis and optical and electrochromic properties of dibenzothiophen-S,S-dioxide and 3-hexylthiophene based polymers. For this purpose a novel dibenzothiophen-S,S-dioxide and 3-hexylthiophene bearing, donor-acceptor-donor type monomer (THSO(2)) was synthesized through Stille cross-coupling reaction. THSO(2) was electrochemically polymerized in tetrabutylammonium hexafluorophosphate- dichloromethane couple. Furthermore, THSO(2) was subjected to electrochemical copolymerization in the presence of 3-hexylthiophene both potentiodynamically and potentiostatically. The resulting homopolymer and copolymers were characterized by means of cyclic voltammetry, FTIR, spectroelectrochemistry and kinetic studies. Depending on the synthesis conditions, the polymers exhibited optical band gaps ranging from 2.23 to 2.60 eV. Moreover, a highly soluble, fluorescent homopolymer was achieved using FeCl(3) as the oxidant. The polymer provides several properties to be used in organic electronic applications.

Solution Processable Benzotriazole, Benzimidazole and Biphenyl Containing Conjugated Copolymers for Optoelectronic Applications Kaya Deniz, Tuğba; Çırpan, Ali; Department of Polymer Science and Technology (2012) The synthesis and optoelectronic properties of biphenyl based conjugated copolymers with varying acceptor units in the polymer backbone were investigated. The well known Donor-Acceptor Theory was used to establish the synthetic pathway for the structural modifications. Solubility issues regarding biphenyl polymer was solved by copolymerizing with soluble units. For this purpose; poly 4-(biphenyl-4-yl)- 4’-tert butylspiro[benzo[d]imidazole-2,1’-cyclohexane] (P1), poly 4-(biphenyl-4-yl)- 2- dodecyl-2H-benzo[d...
Soluble Alkyl Substituted Poly(3,4-Propylenedioxyselenophene)s: A New Platform For Optoelectronic Materials Atak, Samed; Icli-Ozkut, Merve; Önal, Ahmet Muhtar; CİHANER, ATİLLA (Wiley, 2011-10-15) Optical and electrochemical properties of regiosymmetric and soluble alkylenedioxyselenophene-based electrochromic polymers, namely poly(3,3-dibutyl-3,4-dihydro-2H-seleno pheno [3,4-b][1,4]dioxephine) (PProDOS-C(4)), poly(3,3-dihexyl-3,4-dihydro-2H-selenopheno[3,4-b][1,4]dioxephine) (PProDOS-C(6)), and poly(3,3-didecyl-3,4-dihydro-2H-selenopheno[3,4-b][1,4]dioxephine) (PProDOS-C(10)), are highlighted. It is noted that these unique polymers have low bandgaps (1.57-1.65 eV), and they are exceptionally stable ...
Impact modified polyamide-organoclay nanocomposites Işık, Işıl; Yılmazer, Ülkü; Department of Chemical Engineering (2007) The effects of melt state compounding and addition order of ethylene-butyl acrylate-maleic anhydride (E-BA-MAH), ethylene-glycidyl methacrylate (E-GMA), ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer and/or three types of organoclays (Cloisite® 15A, 25A and 30B) on morphology, thermal, mechanical and dynamic mechanical properties of polyamide-6 are investigated. XRD patterns show that the interlayer spacing for Cloisite® 15A remained unchanged; however it increased for the organoclays ...
Preparation and characterization of thermally stable organoclays and their use in polymer based nanocomposites Abdallah, Wissam; Yılmazer, Ülkü; Department of Chemical Engineering (2010) The present study was aimed at exploring the purification and modification of montmorillonite rich Turkish bentonites by organic salts and their subsequent effects on the morphology (X-diffractometry, transmission electron microscopy, scanning electron microscopy), melt flow index, mechanical (Tensile, Impact) and especially thermal stability (thermal gravimetric analysis, differential scanning calorimetry) properties of polymer/organoclay nanocomposites with and without an elastomeric compatibilizer. The b...
SYNTHESIS OF A NEW ELECTROCHROMIC POLYMER BASED ON TETRAPHENYLETHYLENE CORED TETRAKIS CARBAZOLE COMPLEX AND ITS ELECTROCHROMIC DEVICE APPLICATION Carbas, Buket Bezgin; Odabas, Serhat; Turksoy, Figen; Tanyeli, Cihangir (2016-03-01) Poly-1,1,2,2-tetrakis(4-9H-carbazol-9-yl)phenyl)ethene P(TCP) was successfully synthesized by electrochemical oxidation of corresponding monomer, namely, 1,1,2,2-tetrakis(4-9H-carbazol-9-yl)phenyl)ethene (TCP) using dichloromethane as the solvent and tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte.
