Abstract

Sunulan çalışmada, barbitürik asitten türevlendirilen
1,3-dimetil-5-(3,5-dimetilfenil)aminometilenbarbitürat ve
1,3-dimetil-5-(3,5-dimetilfenil)aminometilenbarbitürat bor diflorür kompleksi
başarılı bir şekilde sentezlenmiştir. Sentezlenen bileşiklerin yapısal
karakterizasyonları elementel analiz, ATR FTIR ve NMR spektroskopileri
kullanılarak yapılmıştır. Sentezlenen bileşiklerin lüminesans özelliğe sahip
oldukları mor ötesi ve görünür bölge absorpsiyon spektroskopisi ve floresans emisyon
spektroskopisi kullanılarak belirlenmiştir. Komplekste bulunan BF2
grubunun emisyon bandını kırmızı bölgeye kaydırdığı tespit edilmiştir. Elde
edilen bulgular yeni lüminesans bor bileşiklerinin sentezlenebilmesi için
barbitürat iskeletinin önemli bir potansiyele sahip olduğunu göstermiştir.

Synthesis, characterization of 1,3-dimethyl-5-(3,5-dimethylphenyl)aminomethylenebarbiturate boron difluoride complex and investigation of photophysical properties

Abstract

In the present study, 1,3-dimethyl-5-(3,5-dimethylphenyl)aminomethylenebarbiturate
and 1,3-dimethyl-5-(3,5-dimethylphenyl)aminomethylenebarbiturate boron
difluoride complex were successesfully prepared. The characterizations of
synthesized compounds were done by using elemental analysis, ATR FTIR and NMR
spectroscopies. The synthesized compounds were determined to have luminescence
properties by using ultraviolet-visible absorption and fluorescence emission
spectroscopies. It was determined that the BF2 group in the complex
shifted the emission band to the red zone. The results showed that the
barbiturate framework has a great potential for the synthesis of new
luminescence boron compounds.
