3,4-Ethylenedioxythiophene-quinoxaline based polymer electrode for symmetric supercapacitors on rigid and flexible platforms Cansu Ergun, Emine Gul; Önal, Ahmet Muhtar (2025-12-30) The increasing demand for lightweight, flexible, and reliable energy storage devices drives the exploration of advanced electrode materials for supercapacitors. Conjugated donor-acceptor polymers are promising candidates b...
Hydroxyapatite-Supported Nickel(0) Nanoparticles: A Cost-Effective and Efficient Electrocatalyst for Oxygen Evolution Reaction in Alkaline Media Demir Arabacı, Elif; Akbayrak, Serdar; Önal, Ahmet Muhtar; Özkar, Saim (2025-04-01) Water splitting for hydrogen production is a crucial technology for sustainable energy alternatives. The oxygen evolution process (OER) poses a considerable problem owing to its sluggish kinetics. This study examines the e...
Effect of EDOT contribution on the electrochromic and capacitive properties of edot-carbazole based electrochromic polymer: Electrochromic and supercapacitor device applications Cansu Ergun, Emine Gul; Önal, Ahmet Muhtar (2025-01-10) 3,4-ethylenedioxythiophene (EDOT) based donor-acceptor-donor (DAD) type conjugated polymers generally have extraordinary electrochromic properties due to the excellent nature of the EDOT unit. This work investigates the el...
Electrochromic, Capacitive, and Electrocatalytic Performance of TEMPO Anchored EDOT-SN(T)S-EDOT Electrode Nemutlu, Begüm; Eker, Emre Fatih; Önal, Ahmet Muhtar; Cansu Ergun, Emine Gul; Tanyeli, Cihangir (2025-01-01) Conjugated polymers bearing TEMPO units are successfully used as catalysts for the selective oxidation of primary alcohols. Moreover, such polymers should exhibit satisfactory capacitive properties for energy storage appli...
Fluorine atom effect in D-A-D type conjugated small molecules and polymers Önal, Ahmet Muhtar; Çakal, Deniz; Boztaş, Yalçın (2024-07-24) A new series of monomers in the donor-acceptor-donor array was synthesized by coupling of mono- and difluorinated benzothiadiazole (BT) acceptor units with didecyl-substituted 3,4-propylenedioxythiophene (ProDOT (P)) donor...
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, ...
Synthesis and Characterization of a Luminol Based Chemiluminescent Trimeric System Kesimal, Busra; Balci, Burcu; Çakal, Deniz; Önal, Ahmet Muhtar; Cihaner, Atilla (2023-01-01) A luminol based chemiluminescent trimeric system, namely 2,3-dihydro-5,8-di(thiophen-2-yl)phthalazine-1,4-dione (T2B-Lum), bearing thiophene rings as donor units and 2,3-dihydrophthalazine-1,4-dione as an acceptor unit was...
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...
The Utilization of Iridium Nanoparticles Impregnated on Metal Oxides (Ceria, Titania, and Zirconia) with a Simple and Ecologically Safe Synthesis Approach in Oxygen Evolution Reactions Akbayrak, Merve; Önal, Ahmet Muhtar (2022-07-01) © 2022 The Electrochemical Society (“ECS”). Published on behalf of ECS by IOP Publishing Limited.Oxygen evolution reactions (OERs) have sluggish kinetics, which limits the hydrogen generation from the electrolysis of water...
