Chemical Oxidation of 5-amino quinoline with (NH4)2S2O8: Synthesis and Characterization

Abstract

Ö Z 5 -amino kinolin monomeri (NH 4 ) 2 S 2 O 8 /HCI varlığında kimyasal olarak yükseltgendi. Elde edilen oksidasyon ürününün (OAQ) yapısı, UV-vis, FTIR, 1 HNMR ve 13 CNMR analizleri ile aydınlatıldı. Spektral analizler sonucunda oksidasyon ürünün yapısında fenazin birimlerinin bulunduğu ve momomerik birimlerin birbirleri ile 3,6 ve 8 pozisyonları ile birleştiği belirlendi. Büyüklükçe ayırma tekniği, ürünün oligomerik birimlerden oluştuğunu gösterdi. OAQ ısısal bozunmaya karşı dayanıklıdır. Yarı bozunma sıcaklığının 1000ºC olduğu belirlendi Anahtar KelimelerOksidatif polimerizasyon, 5 -amino kinolin, termal dayanıklılık, floresans. A B S T R A C T5 -amino quinoline (AQ) was chemically oxidized in (NH 4 ) 2 S 2 O 8 /HCI system, whose structure was identified by UV-vis, FTIR, 1 HNMR and 13 CNMR analysis. Spectral analysis results indicated the formation of phenazine like units in the oxidation product and C3, C6, C8 positions of quinoline ring were suggested as a possible polymerization sites. Size exclusion chromatography indicated the oxidation product (OAQ) consisted of oligomeric units (1200 g/mol). OAQ was thermally stable and half of its mass was decomposed at 1000ºC.

“…Due to these properties, they have a wide range of usage including OLED, organic photovoltaic and chemosensor applications [2,3]. The Freandliar reaction, Pd-catalyzed coupling reaction as well as chemical and electrochemical oxidation techniques are well-known methods for production of these polymers [2,4]. Chemical oxidation is one of the effective protocols to obtain polyaromatics.…”
