© 2022For the preparation of conjugated polymers having targeted band gaps, absorption, and optoelectronic properties, the Donor-Acceptor (D-A) approach has been one of the most convenient methods. We synthesized four new conjugated polymers, bearing selenophene and thieno[3,4-c]pyrrole-4,6-dione (TPD) for this study via Suzuki Stille Polycondensation. The effect of selenophene that was inserted as π-bridge and the introduction of a second TPD unit into the polymer backbones through random polymerization were investigated. Optoelectronic properties of the polymers were analyzed via electrochemical and spectroelectrochemical studies. The study reveals the effects of TPD and selenophene moieties on absorption and band gaps of the polymer and provides a concise approach for the preparation of D-A conjugated polymers.

Effect of structural isomerism and polymer end group on the pH-stability of hydrogen-bonded multilayers Erel Göktepe, İrem; Demirel, A. Levent (2011-09-15) Association of tannic acid (TA) with structurally isomeric poly(N-isopropylacrylamide) (PNIPAM) and poly(2-isopropyl-2-oxazoline) (PIPOX) has been examined at surfaces to understand the effect of different molecular arrangements in a polymer repeating unit of structural isomers on the construction and pH-stability of hydrogen-bonded multilayers. Films were fabricated using layer-by-layer (LbL) technique through hydrogen-bonding interactions primarily between carbonyl groups of neutral polymers and hydroxyl ...
Effect of Alkyl Derivatization on Several Properties of N-Halamine Antimicrobial Siloxane Coatings Kocer, Hasan B.; Akdağ, Akın; Ren, Xuehong; Broughton, R. M.; Worley, S. D.; Huang, T. S. (American Chemical Society (ACS), 2008-10-01) Variation of alkyl substitution at position 5 on the hydantoin ring of a series of N-halamine siloxane derivatives has been employed to better understand the biocidal activities of these compounds for use in preparing antimicrobial coatings. The alkyl derivatization of the hydantoin ring at its 5 position, while an essentially constant chlorine loading is maintained at the I position, has shown that there is little dependence of the antimicrobial efficacy against Escherichia coli O157:H7 on the alkyl chain ...
Effect of carboxylic acid crosslinking of cellulose membranes on nanofiltration performance in ethanol and dimethylsulfoxide Konca, Kubra; Çulfaz Emecen, Pınar Zeynep (2019-10-01) Cellulose membranes were fabricated via phase inversion using 1-ethyl-3-methylimidazolium acetate as solvent and acetone as volatile cosolvent. 1,2,3,4-butanetetracarboxylic acid was used to partially crosslink the hydroxyl groups of cellulose, thereby changing mechanical properties of the membranes and the interactions with solvents, ethanol and dimethyl sulfoxide, and solutes. Rejection of dyes of similar size, Bromothymol Blue, Rose Bengal and Crystal Violet were shown to correlate inversely with sorptio...
Effect of Polymers on the Rheological Properties of KCl Polymer Type Drilling Fluid Kök, Mustafa Verşan (2005-05-01) In the course of this research, the effect of two polymers (xanthan gum and polyanionic cellulose) on the rheological properties of KCl/polymer type drilling fluids was investigated. Non-Newtonian drilling fluids are conventionally characterized by rheological models (Bingham Plastic, Power Law, Casson, Herchel-Bulkley and Robertson-Stiff). In this research, forty-five KCl/polymer data sets of varying compositions are prepared. Polymer addition to the system has affected the model and caused a variation of ...
Effects of oxidative functionalized and aminosilanized carbon nanotubes on the crystallization behaviour of polyamide-6 nanocomposites Kaynak, Cevdet (2014-04-01) The purpose of this study is to investigate effects of oxidative functionalized and aminosilanized carbon nanotubes on the (1) isothermal and (2) non-isothermal crystallization kinetics of polyamide-6 by DSC analyses, and (3) crystal structure of injection molded specimens by XRD analyses. Nanocomposites were compounded by using melt mixing technique via twin screw extrusion. Due to basically very effective heterogeneous nucleation effect, both increasing amount and surface functionalization of carbon nanot...
