A new N-halamine precursor, 3-(2,3-dihydroxypropyl)-7,7,9,9-tetramethyl- 1,3,8-triazaspiro[4.5]decane-2,4-dione (TTDD diol), was synthesized and bonded onto cotton fabrics. Fabrics with variable amounts of chlorine loading were prepared by using several concentrations of TTDD diol. A second N-halamine precursor, 3-(3-triethoxysilylpropyl)-7,7,9,9-tetramethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione (TTDD siloxane), was also synthesized and bound to cotton for comparison purposes. The coated cotton fabrics contained two types of N-Cl moieties after chlorination of the amine and amide groups. Swatches with variable chlorine loadings were challenged with Staphylococcus aureus and Escherichia coli O157:H7 as a function of contact time. The biocidal test results showed that the chlorine loadings and surface hydrophobicities influenced the antimicrobial efficacies. The chlorinated swatches have also been employed to oxidize the simulant of chemical mustard to the less toxic sulfoxide derivative.

Fused conjugated structures for organic electronics Cevher, Şevki Can; Çırpan, Ali; Department of Chemistry (2019) In the first application, to investigate the organic light emitting diode device performances three different polymers were synthesized in which fused phenantroimidazole ring was combined with benzotirazole based polymeric backbone. P1 incorporated electroluminescent device exhibited superior performance. The highest luminance efficiency for P1 based device was 3.01 cd/A with a luminance value of 140,180 cd/m2. In the second part, monomer M1 was synthesized and functionalized from ketone (M1) to oxime (M2) ...
Synthesis, spectroscopic and electrochemical studies of perylene containing conjugated copolymers Bayseç, Şebnem; Toppare, Levent Kamil; Yılmaz, Levent; Department of Polymer Science and Technology (2013) The synthesis , spectroscopic and electrochemical properties of a series of donor-acceptor (DA) type polymers by changing the donor unit (thiophene, dithienopyrrole) polymer backbone were investigated.The synthesized CoP1 and CoP2 were designed to investigate the effect of copolymerization and insertion of perylene tetracarboxylic dimide (PDI) on the structure of benzotriazole (BTz) based polymers. For CoP1 1,7-dibromo-perylene diimide,4,7-dibromo-2-dodecyl-2H-benzo[d][1,2,3]triazole and 2,5 bis(tributylsta...
Synthesis and characterization of conjugated polymers with polyhedral oligomeric silsesquioxane pendant groups Ertan, Salih; Kaynak, Cevdet; Cihaner, Atilla; Department of Polymer Science and Technology (2017) In this thesis, a series of monomers covalently bonded to polyhedral oligomeric silsesquioxane (POSS) pendant group was designed and synthesized. POSS group is a hybrid organic-inorganic nanostructure with 1 to 3 nm diameter. POSS which has a cage structure is mainly composed of silicon (Si) (at vertices) and oxygen (O) (in the middle of the edge). POSS nanostructure can be modified through the vertices with organic functional groups. POSS groups provide different properties, such as thermal robustness, mec...
Preparation of a conducting flexible material from silane coupling agent and hydroxyl terminated polybutadiene rubber by hydrolysis and condensation Karatas, Y; Toppare, Levent Kamil; Tincer, T (Informa UK Limited, 2003-01-01) Synthesis and characterization of a flexible polymer produced from silane coupling agent (SCA) and hydroxyl terminated polybutadiene (HTPB) were performed. Mechanical properties of chemically and electrochemically prepared conducting composites synthesized from this polymer were investigated. Conductivities of the composites were also measured. Polypyrrole enhanced the mechanical properties of the chemically prepared conducting composite. Doping with iodine greatly changed the conductivity of the composite....
Highly Conjugated Thiophene Derivatives as New Visible Light Sensitive Photoinitiators for Cationic Polymerization Aydogan, Binnur; Günbaş, Emrullah Görkem; Durmus, Asuman; Toppare, Levent Kamil; Yağcı, Yusuf (2010-01-12) A visible light sensitive photoinitiator system for the cationic polymerization of typical monomers, e.g. of oxiranes such as cyclohexene oxide, of vinyl ethers such as n-butyl vinyl ether, and of other vinyl monomers such its N-vinylcarbazole, using highly conjugated thiophene derivatives is described. The cationic polymerization of these monomers was initiated at room temperature upon irradiation in the visible region (lambda(inc) = 480 nm) in CH2Cl2 solutions with 4,7-di(2,3-dihydrothieno[3,4-b][1,4]diox...
