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.

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...
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 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...

Apaydın, Doğukan Hazar; Toppare, Levent Kamil; Department of Polymer Science and Technology (2012)
Three new azobenzene containing conjugated monomers were designed and synthesized. Resulting monomers were characterized by means of 1H NMR and 13C NMR techniques. Monomers (E)-1,2-bis(4-(thiophen-2-yl)phenyl)diazene (M1), (E)-1,2-bis(4-(4-hexylthiophen-2-yl) phenyl) diazene (M2) and (E)-1,2-bis(2-fluoro-4-(4-hexylthiophen-2-yl)phenyl) diazene (M3) were electrochemically polymerized using cyclic voltammetry to give polymers P1, P2 and P3. The polymers were subjected to spectroelectrochemical and kinetic stu...
Electrochromism in multichromic conjugated polymers: Thiophene and azobenzene derivatives on the main chain
Apaydin, Dogukan Hazar; Akpinar, Hava; Sendur, Merve; Toppare, Levent Kamil (2012-01-15)
Novel donor-acceptor-donor type polymers containing azobenzene group in polymer backbone chains were synthesized and their electrochromic properties were investigated. To increase the strength of the acceptor unit, fluorinated azobenzene containing donor-acceptor-donor type polymer was also synthesized. Cyclic voltammetry and spectroelectrochemistry studies showed that poly((E)-1,2-bis(4-(4-hexylthiophen-2-yl)phenyl)diazene) (P2) and poly((E)-1,2-bis(2-fluoro-4-(4-hexylthiophen-2-yl)phenyl) diazene) (P3) we...
