Synthesis and investigation of spectroscopic properties of bodipy derivatives prepared with 2,4-dimethylpyrrole

Abstract

In this study, two Bodipy compounds were prepared using 2,4-dimethyl pyrrole. Column chromatography was used at every stage of the synthesis in order to obtain the synthesized intermediates and target compounds in a pure form. The pure products obtained were characterized by various methods. First, melting point determination was made and FT-IR spectra were collected. After functional group analysis with FT-IR spectroscopy, 1H-NMR and 13C-NMR spectra of the compounds were taken in deutero-chloroform. The obtained compounds are given short names as B-Cl and B1. After the characterization processes, the spectroscopic properties of the compounds were investigated by fluorescence spectroscopy and UV-vis spectroscopy. In addition, the effect of the solvent on the fluorescence properties of the prepared compounds was investigated.

2,4-Dimetilpirol ile hazırlanan bodipy türevlerinin sentezi ve spektroskopik özelliklerinin incelenmesi

Abstract

Bu çalışmada 2,4-dimetil pirol kullanılarak iki adet Bodipy bileşiği hazırlanmıştır. Sentezlenen ara ürünler ve hedef bileşiklerin saf bir şekilde elde edilebilmesi için sentezin her aşamasında kolon kromatografisinden faydalanılmıştır. Elde edilen saf ürünler çeşitli metotlar ile karakterize edilmiştir. lk olarak erime noktası tayini yapılmış ve FT-IR spektrumları toplanmıştır. FT-IR spektroskopisi ile fonksiyonel grup analizleri yapıldıktan sonra, bileşiklerin dötöro-kloroform içerisinde 1H-NMR ve 13C-NMR spektrumları alınmıştır. Elde edilen bileşiklere B-Cl ve B1, olarak kısa isimler ile verilmiştir. Karakterizasyon işlemlerinden sonra bileşiklerinin spektroskopik özellikleri, floresans spektroskopisi ve UV-vis spektroskopisi ile incelenmiştir. Ayrıca hazırlanan bileşiklerin floresans özelliklerine çözücünün etkisi de araştırılmıştır.
