Özet
Bu çalışmada sülfo grubu içeren, 3-aminobenzensülfonikasit’in 2,5-
dihidroksibenzaldehit ve 3,4-dihidroksibenzaldehit ile kondenzasyon reaksiyonu
sonucu sırasıyla L
I
(sodium(Z)-3-((2,5-dihydroxybenzylidene)amino)benzenesulfonate
ve L
II (sodium(Z) 3((3,4-dihydroxybenzylidene)amino)benzenesulfonate) olmak
üzere suda çözünebilen iki farklı yeni Schiff Bazı ligandı ve Cu(II), Co(II), Ni(II) ve
Zn(II) metal kompleksleri sentezlendi. Sentezlenen bu Schiff bazı ligandlarının ve metal
komplekslerinin kimyasal yapıları erime noktası tayini, elementel analiz, FT-IR ve 1HNMR teknikleriyle karakterize edildi. Sentezlenen L
I
ve L
II
ligandlarının elektrokimyasal
davranışları dönüşümlü voltametri tekniği ile incelendi. Elektrot yüzeyleri, su temas açısı
ölçümü, taramalı elektron mikroskobu (SEM), atomik kuvvet mikroskobu(AFM),
ferrosen ve potasyum hekzasiyanoferrat (III) redoks probları varlığında dönüşümlü
voltametri tekniği ile karakterize edildi. Yalın GC, LI
/GC ve LII/GC yüzeyleri arasındaki
farklılıkları karşılaştırmak amacıyla yapılan karakterizasyon sonucu elde edilen veriler
değerlendirildi. Elektrokimyasal analizlerden elde edilen sonuçlar ile Schiff baz
ligandlarına ait teorik hesaplamalar (DFT) karşılaştırıldı. Sentezlenen Schiff bazı ligandı
ve metal komplekslerinin suda çözünebilme özelliğinden yararlanılarak yeşil kimya
alanındaki tüm çalışmalarda kullanılması mümkündür.
In this study, as a result of condensation reaction of 3-aminobenzenesulphonic acid containing sulfo group with 2,5 dihydroxybenzaldehyde and 3,4- dihydroxybenzaldehyde, (L I (sodium(Z)-3-((2,5dihydroxybenzylidene)amino) benzenesulfonate) ve L II (sodium(Z) 3((3,4-dihydroxybenzylidene)amino)benzenesulfonate) two different water-soluble Schiff Base ligands and metal complexes were synthesized. The chemical structures of these synthesized Schiff base ligands and metal complexes were characterized by melting point determination, elemental analysis, FT-IR and 1H NMR techniques. The electrochemical behavior of the synthesized LI and LII ligands was investigated by the alternating voltammetry technique. Electrode surfaces were characterized by water contact angle measurement, scanning electron microscopy (SEM), atomic force microscope (AFM), ferrocene and potassium hexacyanoferrate (III) redox probes in the presence of alternating voltammetry technique. The data obtained as a result of the characterization were evaluated in order to determine the differences between the plain and modified surfaces and to discuss the effects of the positions of the functional groups in the structure of Schiff base ligands. The results obtained from the electrochemical analyzes were compared with the theoretical calculations (DFT) of Schiff base ligands. It is possible to use the synthesized Schiff base ligand and metal complexes in all studies in the field of green chemistry by utilizing their water solubility feature.
