Öğe Catalytic and biological activities of homoleptic palladium(II) complexes bearing the 2-aminobenzothiazole moiety(Elsevier, 2021) Dayan, Serkan; Tercan, Melek; Özdemir, Fethi Ahmet; Aykutoğlu, Gürkan; Özdemir, Namık; Şerbetçi, Zafer; Dinçer, Muharrem; Dayan, OsmanThe palladium(II) complexes PdL1-3, bearing bi-dentated Schiff base ligands (L1-3) were synthesized and characterized by FT-IR, NMR and single crystal-XRD techniques, and the structural, spectroscopic and electronic properties were obtained using the B3LYP density functional method (DFT). The fabricated complexes were used as catalysts in the reduction of some organic pollutants (4-nitrophenol (4-NP), Rhodamine B (Rh B) and methylene blue (MB)) in water at an ambient temperature. The PdL3 complex was recorded as the best catalyst compared to the other complexes and the highest conversion rates were in the order of MB > RhB > 4-NP. Also, the antimicrobial and antifungal activities of all the compounds (ligands and complexes) and the cytotoxic effects on DU-145 and SH-SY5Y cells were investigated. The PdL1-3 complexes show cytotoxic effects, especially against the SH-SY5Y cells. All the synthesized com- pounds showed moderate antimicrobial and antifungal properties.Öğe Catalytic and biological properties of palladium(II) complexes with bidentate Schiff base ligands(John Wiley and Sons Ltd, 2023) Dervişoğlu, Gökhan; Özdemir, Fethi Ahmet; Özdemir, Namık; Şerbetçi, Zafer; Dayan, Osman; Kaya Özgür, GizemIn this study, we synthesized and characterized Schiff base ligands (S1–3), which contained sulfonamide/sulfonate groups, and their corresponding Pd(II) complexes (K1–3). We also introduced these complexes into Al2O3-supported materials (M1–3) using the impregnation method. Following the structural characterization, we proceeded to evaluate the performance of the supported materials in a series of degradation and reduction reactions of involving organic pollutants. These assessments were conducted with the intention of exploring their potential as catalysts in aqueous environments in the presence of NaBH4. The study's findings present novel approaches to develop effective catalysts for reducing/degrading organic pollutants in aqueous environments. The M2 catalyst showed excellent results for dye mixing after 90 s. Additionally, we investigated the antibacterial and cytotoxic properties of the synthesized compounds. The outcome also suggests that these synthesized compounds exhibit potential antibacterial and cytotoxic properties.Öğe Synthesis, catalytic, cytotoxic, and antibacterial properties of new Ru(II) and Pd(II) complexes bearing bidentate Schiff base ligand(Taylor and Francis Ltd., 2021) Selvi, Gizem; Özdemir, Fethi Ahmet; Aykutoğlu, Gürkan; Özdemir, Namık; Şerbetçi, Zafer; Dinçer, Muharrem; Dayan, OsmanIn the present study, new Ru(II) and Pd(II) complexes with sulfonated bidentate Schiff base ligand were synthesized and structurally characterized by NMR, FT-IR, MS spectroscopic methods. Additionally, the solid-state structure of the Schiff base ligand was determined with a single crystal-XRD technique. Then, the antibacterial properties and in vitro cytotoxicity of the synthesized compounds were investigated. Also, the catalytic activities of the Ru(II) and Pd(II) complexes were examined comparatively for the degradation of Eosin Yellow.Öğe Yeni Rutenyum Boyalar: Güneş Pilleri için Deneysel ve Teorik Araştırma(2016) Dayan, Osman; Bilici, Ali; Şerbetçi, Zafer; Özdemir, Namık[Abstract Not Available]
