dc.description.abstractBu çalışmada, bazı aromatik ve karbosiklik heterosiklik aldehitlerle 1,3-dimetilbarbitürik asidin Knoevenagel kondensasyonu ile bir seri merosiyanin boyarmaddesi sentezlendi. Bileşiklerin yapıları FT-IR, 1HNMR ve UV-VIS spektrumları ile aydınlatıldı. Boyarmaddelerin absorpsiyon spektrumları üzerine sübstituentlerin ve heterohalkaların etkisi incelendi. Ayrıca bileşiklerin absorpsiyon spektrumları çeşitli çözücüler içinde kaydedildi. Genel olarak, elektron veren sübstitüent içeren karboksiklik aldehitlerden elde edilen boyarmaddeler pozitif solvatokromizm gösterdi.
dc.description.abstractIn this study, a range of merocyanine dyes has been synthesized by Knoevenagel condensation of 1,3-dimethylbarbituric acid with some aromatic carbocyclic and heterocyclic aldehydes. The structure of compounds was confirmed by FT-IR, 1H NMR and UV-VIS spectra . The effecct of substituent and heterorings on absorption spektra of the dyes were investigated . In addition, absorption spektra of the dyes were recorded in various solvents. Ingeneral, the dyes prepared from electron donating substituted carbocyclic aldehydes showed a positive solvatochromism.en_US
