The role of donor units in band gap engineering of donor–acceptor conjugated polymers Haciefendioglu, Tugba; Yıldırım, Erol (2025-07-01) Most used 60 distinct electron-donating units have been modelled, analyzed, and compared using density functional theory (DFT) for tetramer structures in the form (D–B–A–B)4 with fixed acceptor and bridge units, where D, A...
A combined experimental and computational study of electron transfer in the light harvesting perylenediimide-poly(p-phenylene) supramolecular dyad El-Khouly, Mohamed E.; Kobaisy, Ahmed M.; Yıldırım, Erol; El-Shafei, Ahmed (2025-06-01) A novel supramolecular dyad, composed of the electron-accepting N,N’-di(2-(trimethylammoniumiodide) ethylene) perylenediimide (TAIPDI) and the electron donating electron-donating poly[2,5-bis(3-sulfonatopropoxy)-1,4-phenyl...
The Role of Polyisobutylene-Bis-Succinimide (PIBSI) Dispersants in Lubricant Oils on the Deposit Control Mechanism Özdemir, Erhan; Kan, Esra; Guo, Binbin; Pashkovski, Eugene; Agiral, Anil; Yıldırım, Erol (2025-04-01) Molecular modeling calculations for the design and improvement of next-generation additives for motor oils have reached a level that can support and improve experimental results. The regulation of insoluble sludge nanopart...
Enantioselective Addition of 1,3,5,7-Tetramethyl-BODIPYs to Isatins by Bifunctional Quinine-Based Squaramides Dündar, Esra; Isik, Murat; Yıldırım, Erol; Tanyeli, Cihangir (2025-01-01) This work describes the development of the first enantioselective addition reaction between 1,3,5,7-tetramethyl-BODIPYs and isatin derivatives. The reaction utilizes bifunctional quinine/squaramide organocatalysts and affo...
Design and performance of sulfur and selenium-substituted triarylboron D3-A TADF emitters for OLED applications Karakurt, Oğuzhan; Demirgezer, Elif Fatma; Daştemir, Murat; Cakmaktepe, Semih Can; Miranda-Salinas, Hector; Aksoy, Erkan; Danos, Andrew; Monkman, Andrew; Yıldırım, Erol; Çırpan, Ali (2024-11-01) This study presents the design, synthesis, and comprehensive theoretical and photophysical analysis of two new D3-A type thermally activated delayed fluorescence (TADF) emitters for organic light-emitting diode (OLED) appl...
Theoretical investigation on graphene induced self-alignment of donor-acceptor structures Haciefendioglu, Tugba; Aytemiz, Muhammet E.K.; Korhan, Hamza; Yıldırım, Erol (2024-06-20) Non-covalent functionalization of graphene (Gr) with conducting polymers (CPs) improves the electrical and mechanical properties of both materials owing to the noncovalent π-π stacking interaction between the surface and t...
Multiscale Modeling Approach to Understand Mechanism of Deposit Control by Sulfonate-Based Lubricant Detergents Özdemir, Erhan; Kan, Esra; Guo, Binbin; Pashkovski, Eugene; Agiral, Anil; Yıldırım, Erol (2024-01-01) Protecting the material surfaces from deposits and insoluble sludge particles extends the engine life and reduces waste. Lubricant detergents in engine oils are essential additive technologies that prevent deposit formatio...
