Floresan Özellikli Boya içeren ZnO Nanokompozit Kopolimerlerin Elektrokimyasal Sentezi ve Karakterizasyonu

Floresans boya sınıfından olan BODIPY’nin (Boron dipirolmetilen) bilim insanları tarafından sentezi uğraştırıcı olmasına karşın floresan, iyon / molekül ve pH probları, sensörler, redoks aktif moleküller, metal şelatörler, hücresel görüntüleme, fotodinamik tedavi, ilaç teslim malzemeleri ve fotovoltaik uygulamalar ve enerji depolama gibi çok çeşitli uygulamalarda kullanılması ilgi çekici olmuştur. Öncelikle çalışmada sentezi zor ama çekici floresans aktif monomer başarı ile sentezlenmiştir. Sonra elektrokimyasal yöntem kullanılarak yenilikçi malzeme olan bir iletken kopolimer sentezlenmiştir. Elde edilen yarı iletken malzemenin dayanım, iletkenlik özelliklerini arttırmak için Zno nanopartikülleri kullanılarak yine bir potansiyostat yardımı ile nanokompozit sentezlenmiş ve varlığı SEM-EDX, AFM-Raman gibi ileri teknolojik cihazlarla tayin edilmiştir. ZnO gibi inorganik ve nano ölçekli bileşiklerin karakteristik pikleri geleneksel FT-IR cihazında parmak izi bölgesinde ve zayıf/orta gözlenmektedir. Buda bahsedilen bileşiklerin kızılötesi spektrometre ile nitel teşhisini zorlaştırmaktadır. Buna karşın Raman spektroskopisi hem ICP-MS gibi nispeten uğraştırıcı hem de FT-IR gibi karmaşık bir spektrum bölgesi olmadığından nano parçacıkların tayininde tercih edilmiştir.

Electrochemical Synthesis and Characterization of ZnO Nanocomposite Copolymer Containing Fluorescent Feature Dye

BODIPY (boron dipyrrolmethene) has attracted the attention of scientists although the synthesis ofBODIPY from the fluorescent dye class is challenging, there are many applications such as fluorescence, ion /molecule and pH probes, sensors, redox active molecules, metal chelators, cellular imaging, photodynamictherapy, drug delivery materials and photovoltaic applications and energy storage. Firstly, it is synthesized withdifficulty in synthesis but attractive fluorescence active monomer. Then, by electrochemical method, aconductive copolymer, which is an innovative material, was synthesized. The nanocomposite was synthesizedwith the help of a potentiostat using Zno nanoparticles to increase the strength and conductivity properties ofthe obtained semiconducting material and its existence was determined by advanced technological devices suchas SEM-EDX, AFM-Raman. Characteristic peaks of inorganic and nano-scale compounds such as ZnO areobserved in the fingerprint region and weak / medium in the conventional FT-IR device. This makes it difficultto qualitatively diagnose the compounds by infrared spectrometry. Raman spectroscopy, however, has beenpreferred for the determination of nanoparticles because it is relatively laborious, such as ICP-MS, and is not acomplex spectral region such as FT-IR.
