Abstract
In this study, N,N’-(dodecane-1,12-diyl)bis(2,4-dichlorobenzamide) and N,N’- (dodecane-1,12-diyl)bis(4-bromobenzamide) as new bis-benzamides were syn- thesized by reaction of 1,12-diaminododecane and two different acyl chloride compounds in 88% and 92% yield, respectively. Their molecular structures were characterized using 1H NMR, 13C NMR and FT-IR techniques. Antibacterial activities of the synthesized compounds were screened against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 strains. Moreover, pho- tophysical properties of the products in CH Cl and CHCl were investigated us- 2 2 3 ing UV-vis spectroscopy. The compound 3a exhibited positive solvatochromism about 31 nm by increasing of solvent polarity. Bu çalışmada, 1,12-diaminododekan ve iki farklı açil klorür bileşiğinin reaksiyonu ile N,N'-(dodekan-1,12-diil)bis(2,4-diklorobenzamid) ve N,N'-(dodekan-1,12-diil)bis(4-bromobenzamid) olmak üzere yeni bis-benzamidler sırasıyla %88 ve %92 verimle sentezlendi. Moleküler yapıları 1H NMR, 13C NMR ve FT-IR teknikleri kullanılarak karakterize edildi. Sentezlenen bileşiklerin antibakteriyel aktiviteleri Staphylococcus aureus ATCC 25923 ve Escherichia coli ATCC 25922 suşlarına karşı tarandı. Ayrıca, CH2Cl2 ve CHCl3 içindeki ürünlerin fotofiziksel özellikleri UV-vis spektroskopisi kullanılarak incelendi. Bileşik 3a, çözücü polaritesinin artmasıyla yaklaşık 31 nm'de pozitif solvatokromizm gösterdi.Keywords
