The effect of branched versus linear side chain on thieno[3,4-c]pyrrole-4,6-dione-based donor-acceptor-donor type monomers and their p- and n-dopable polymers Demir Arabacı, Elif; Çakal, Deniz (2023-08-08) The conjugated backbone has been the focus of the most research, while the structure of the side chains has received less attention. Here, we focus on making new donor–acceptor–donor (D–A–D) type conjugated monomers by bea...
Theoretical and experimental investigation of bridging atom effect on the fluorene and silafluorene based trimeric monomers and their corresponding polymers Demir Arabacı, Elif; Yıldırım, Erol; Önal, Ahmet Muhtar (2023-08-01) A series of monomers bearing fluorene and silafluorene with different bridging atoms and 3,4-ethylenedioxythiophene (EDOT) and 3,4-propylenedioxythiophene (ProDOT) as the donor units were synthesized via Stille coupling. T...
Effect of phthalimide and thieno[3,4-c]pyrrole-4,6,dione acceptors on π-conjugated donor-acceptor-donor monomers: Experimental and theoretical investigations of photophysical and electrochemical properties Çakal, Deniz; Demir Arabacı, Elif; Yıldırım, Erol; Cihaner, Atilla; Önal, Ahmet Muhtar (2023-06-29) In this study, two novel donor-acceptor-donor monomers were synthesized by coupling a phthalimide (PI) acceptor unit with thiophene (T) and ethylenedioxythiophene (EDOT (E)) donor units. These two novel PI-based monomers, ...
Side chain effect on the electrochemical and optical properties of thieno[3,4-c]pyrrole-4,6-dione based donor-acceptor donor type monomers and polymers Çakal, Deniz; Demir Arabacı, Elif; Yıldırım, Erol; CİHANER, ATİLLA; Önal, Ahmet Muhtar (2022-09-01) In organic pi-conjugated materials, side chains play great roles that impact far beyond solubility. In this work, we mainly focused on the synthesis of new donor-acceptor-donor (D-A-D) type conjugated monomers and their co...
Ceria Supported Nickel(0) Nanoparticles: A Highly Active and Low Cost Electrocatalyst for Hydrogen Evolution Reaction Demir Arabacı, Elif; Önal, Ahmet Muhtar; Özkar, Saim (2020-06-01) Herein, we report the development of a nickel-based catalyst obtained by reduction of Ni(2+)ions on the surface of ceria nanopowder using aqueous solution of NaBH4. The catalyst was characterized by X-ray diffraction (XRD)...
Ceria supported ruthenium(0) nanoparticles: Highly efficient catalysts in oxygen evolution reaction Demir Arabacı, Elif; Önal, Ahmet Muhtar; Özkar, Saim (2019-01-15) Ruthenium(0) nanoparticles were successfully prepared on the surface of ceria (Ru-0/CeO2) and used as catalysts on glassy carbon electrode (GCE) in oxygen evolution reaction (OER) from water electrolysis at room temperatur...
Titania, zirconia and hafnia supported ruthenium(0) nanoparticles: Highly active hydrogen evolution catalysts Demir Arabacı, Elif; Önal, Ahmet Muhtar; Özkar, Saim (Elsevier BV, 2018-12-01) Designing a cost-effective catalyst with high activity and stability for hydrogen evolution reaction (2H(+) + 2e(-) -> H-2) is a big challenge due to increasing demand for energy. Herein, we report the electrocatalytic act...
Nanoceria-Supported Ruthenium(0) Nanoparticles: Highly Active and Stable Catalysts for Hydrogen Evolution from Water Demir Arabacı, Elif; Önal, Ahmet Muhtar (American Chemical Society (ACS), 2018-02-21) Ruthenium(0) nanoparticles supported on nanoceria (Ru-0/CeO2) were prepared by reduction of Ru3+ ions on the surface of ceria using aqueous solution of NaBH4. The Ru-0/CeO2 samples were characterized by advanced analytical...
