Conducting polymers have gained great interest recently due to their fascinating properties such as; solution processability, easy band gap alternation via structural modification, low cost and flexibility. Conducting polymers have variety of application fields like solar cells (OPVs), electrochromic devices, biosensors and light emitting diodes. Up to date, the donor-acceptor (D-synthesis of conducting polymers to obtain low band gap polymers for desired applications. Recently, quinoxaline and benzodithiophene units are widely used for donor and acceptor type aromatic heterocycles to achieve low band gap polymers. Herein, a novel multifunctional quinoxaline and benzodithiophene comprising polymer, namely poly[5-(5-(4,8-bis ((2-ethylhexyl)oxy) benzo[1,2-b:4,5-b']dithiophen-2-yl) selenophen-2-yl)-2,3-bis (3,4-bis(octyloxy)phenyl)-8-(selenophen-2-yl)quinoxaline], with selenophene-bridge was synthesized. The resulting polymer was characterized with electrochemical, spectroelectrochemical and electrochromic studies. The polymer exhibited low oxidation potential at 0.76 V with 1.74 eV optical band gap and multichromic redox states. These properties make the polymer a good candidate for electrochromic applications.

Synthesis and characterization of water soluble polymer stabilized transition metal(0) nanoclusters as catalyst in hydrogen generation from the hydrolysis of sodium borohydride and ammonia borane
Metin, Önder; Özkar, Saim; Department of Chemistry (2010)
Metal nanoclusters exhibit unique properties which differ from their bulk materials, owing to the quantum size effects. For example, the catalytic activity of transition metal nanoclusters generally increases with decreasing particle size. However, nanoclusters tend to be fairly unstable with respect to the agglomerate into bulk metal in solution and thus special precautions have to be taken to avoid their aggregation or precipitation during the preparation of such nanoclusters in solution. In order to obta...
Synthesis of uniformly distributed single- and double-sided zinc oxide (ZnO) nanocombs
Yıldırım, Özlem Altıntaş; Liu, Yuzi; Petford-Long, Amanda K. (Elsevier BV, 2015-11-15)
Uniformly distributed single- and double-sided zinc oxide (ZnO) nanocomb structures have been prepared by a vapor-liquid-solid technique from a mixture of ZnO nanoparticles and graphene nanoplatelets. The ZnO seed nanoparticles were synthesized via a simple precipitation method. The structure of the ZnO nanocombs could easily be controlled by tuning the carrier-gas flow rate during growth. Higher flow rate resulted in the formation of uniformly-distributed single-sided comb structures with nanonail-shaped t...

Noble metal incorporated MCM-41 based nanostructured mesoporous materials have attracted the attention of material researchers in recent years. Sorption characteristics of MCM materials can be improved by surface modification techniques. Besides surface modification, metal nanoparticles can also be produced within the pores of mesoporous materials. MCM-41 can act as host for several metal nanoparticles such as palladium. The present study is focused on the synthesis of Pd-MCM-41 nanocomposite catalytic mate...

Büyükyağcı, Arzu; Aras, Leyla; Department of Chemistry (2004)
Incorporation of monoacetylferrocene to the sulfonated polystyrene ionomers imparted some changes in the properties of sulfonated polystyrene. Sulfonation was carried out by acetic anhydride and concentrated sulphuric acid. The sulfonation reaction and the degree of sulfonation were determined by analytical titration and adiabatic bomb calorimeter . For this purpose, sulfonated polystyrene (SPS) samples with varying percentages of sulfonation were prepared between 0.85% and 6.51%. Monoacetyl ferrocene was u...

Zinc oxide (ZnO) nanostructures have attracted considerable attention in many electrical, optoelectronic and magnetic applications due to their unique properties originating form characteristic wide band gap and large exciton binding energy of ZnO. Electrical, optical and magnetic properties of ZnO nanostructures strongly depend on their size and morphology. Therefore, there has been a strong interest in the synthesis of ZnO nanostructures with well-controlled size and shape. These synthesis approaches shou...
