Son yıllarda, iletken polimerler, esnek yapılı, oda sıcaklığında işlenebilir ve elektrokromik özellikleri sebebiyle iletken organik malzemeler olarak dikkat çekmektedir. Fakat, yüksek kontrastlı elektrokromik iletken polimerler literatürde sınırlıdır. Amid sübstitiye ditiyenil pirol (SNS) türevleri mevcut literatürdeki iletken polimerlere göre bu bakımdan oldukça avantajlıdır. Bu yapılar içerisinde sentezlemiş olduğumuz N-(2,5-di(tiyofen-2-yil)-1H-pirol-1-yil)benzamid (PBA) molekülü yüksek kontrast ve dayanıklılığı ile dikkat çekmektedir. Yapılan bu çalışmada, çalışma elektrotu olarak kullanılan İndiyum-Kalay Oksit kaplı cam elektrot (ITO) yüzeyi indirgenmiş grafen oksit (rGO) ile modifiye edilerek kullanılmıştır. Yapılan modifikasyon ile rGO kaplanarak iletkenliği arttırılan elektrot yüzeyinde oluşturulan pPBA filmine ait spektroelektrokimyasal özellikler incelenmiştir. Elde edilen bulgular, rGO kaplı yüzeyde oluşturulan iletken polimer filmine ait kararlılığın, optik kontrastın ve yük yoğunluğunun istenildiği gibi önemli oranda arttırıldığını göstermektedir.
In recent years, conductive polymers, flexible, can be processed at room temperature and are attracted as conductive organic materials due to their electrochromic properties. However, high contrast electrochromic conductive polymers are limited in literature. The derivatives of pyrol (SNS) referred to as amid substities are quite advantageous in this regard compared to the conductive polymers in current literature. The molecule of N-(2,5-di(tiophen-2-a)-1H-pirol-1-a)benzamid (PBA) which we have synthesized within these structures is high in contrast and resistance. In this study, the Indyum-Kalay oxide covered glass electrots (ITO) used as the work electrots were modified with reduced graphene oxide (rGO) surface. With the modification made, the spectral-electrochemical characteristics of the pPBA film created on the electrot surface increased conductivity by covering rGO have been studied. The findings show that the stability, optical contrast and load intensity of the conductive polymer film created on the rGO-covered surface have been significantly increased as desired.
In recent years, conductive polymers have attracted attention as conductive organic materials due to their flexible structure, processability at room temperature and electrochromic properties. However, the high-contrast electrochromic conductive polymers are limited in the literature. Amide substituted dithienylpyrrole (SNS) derivatives has advantage compared to conductive polymers in the literature. In these materials, the N- (2,5-di (thiophen-2-yl) -1H-pyrrol-1-yl) benzamide (PBA) molecule has remarkabled for its high contrast and stability. In this study, the working electrode surface which is indium-tin oxide coated glass electrode (ITO) was modified with reduced graphene oxide (rGO). After the modification, the spectroelectrochemical properties of the formed pPBA film on the surface of the working electrode which increases the conductivity by rGO coating were investigated. The obtained results show that the stability, optical contrast and charge density of the formed conductive polymer film on the rGO-coated surface, are significantly increased as desired.
