Abstract

m ÖZET Bu çalışmada, bileşikler iki aşamada sentezlendi. Birinci aşamada anilin, 4- metilanilin, 4-etilanilin, 4-tert-bütilanilin, 4-nitroanilin, 4-floranilin, 4-kloranilin, 4- bromanilin ve 4-metoksianilin diazolanıp, fenol ve 2,6-dimetilfenol ile kenetlenerek karşılık gelen 4-hidroksiazobenzen türevleri elde edildi. İkinci aşamada ise 4- hidroksiazobenzen türevi boyarmaddeler, akriloil klorür ile etkileştirilerek karşılık gelen akriloil türevleri sentezlendi. Sentezlenen boyarmaddelerin saflık kontrolleri ince tabaka kromatoğrafisi ve erime noktası ile gerçekleştirildikten sonra yapılan UV-VIS, İR, 'H-NMR, 13C-NMR teknikleri kullamlarak incelendi, ayrıca tek kristalleri hazırlanabilen bileşiklerin moleküler yapılan X-ışınlan difraksiyon yöntemiyle de belirlendi. Anahtar Kelimeler: Azo, diazen, boyarmadde, akriloil, akriloiloksi, 4- hidroksiazobenzen ve akriloil türevleri, polimerleşebilen azo bileşikleri

IV ABSTRACT In this study, compounds have been synthesised in two steps. In the first step, aniline, 4-methylaniline, 4-ethylaniline, 4-tert-butylaniline, 4-nitroaniline, 4- floroaniline, 4-chloroaniIine, 4-bromoaniline, and 4-methoxylaniline have been diazotized and their diazonium salts inunediately have been coupled with phenol and 2,6-dimethylphenol. In the second step, 4-hydroxyazobenzene derivatives were treated with acryloyl chloride and corresponding acryloyl derivatives were obtained. After the purity control of dyes synthesized by thin layer chromatography and melting points determination, the structures of these compounds have been determined by employing UV-VIS, IR, 'H-NMR, 13C-NMR spectroscopic techniques. In addition, single crystals of the same compounds were prepared and structures were investigated by X-Ray crystallographic studies. Key Words: Azo, diazen, dyes, acryloyl, acryloyloxy, azo dyes, 4-hydroxyazobenzene derivatives and their acryloyloxy derivatives, polymeryzable azo dyes.
