Abstract

In this study, where 2-amino-1,3,4-thiadiazole and 5-mercapto-2-amino-1,3,4-thiadiazole compounds were used as starting materials, five new azo dyes were synthesized using 3-amino-5-methyl pyrazolone, 3-amino-1-phenyl-5-methyl pyrazolone, and barbutyric acid as coupling components. 1H-NMR and FT-IR spectroscopic methods determined the molecular structures of the synthesized compounds. In addition, UV-Vis and absorption spectra of the synthesized compounds were taken, and their solvatochromic properties were investigated. As a result of absorption studies, positive solvatochromism was observed in the synthesis compounds.

Özet

2-amino-1,3,4-tiyadiazol ve 5-merkapto-2-amino-1,3,4-tiyadiazol bileşiklerinin başlangıç maddesi olarak kullanıldığı bu çalışmada; 3-amino-5-metil pirazolon, 3-amino-1-fenil-5-metil pirazolon ve barbütirik asitin kenetleme bileşenleri olarak kullanıldığı beş yeni azo boyarmadde sentezlenmiştir. Sentezlenen bileşiklerin moleküler yapıları 1H-NMR, FT-IR spektroskopik yöntemleri ile belirlenmiştir. Ayrıca, sentezlenen bileşiklerin UV-Vis. absorpsiyon spektrumları alınmış ve solvatokromik özellikleri incelenmiştir. Absorpsiyon çalışmaları sonucunda, sentezlenen bileşiklerde pozitif solvatokromizm gözlenmiştir.
