Abstract:

 

In this study; a novel monomer 1,5-(1-pyrrolyl)-9,10-anthraquinone which contains pyrrole (Py) and anthraquinone was synthesized. The structure of the synthesized novel monomer was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and 1H-NMR Spectroscopy methods; electrochemical behavior of the monomer was investigated by cyclic voltammetry (CV) method. Electropolymerization of 1,5-(1-pyrrolyl)-9,10-anthraquinone monomer in nitrobenzene solvent medium that contains supporting electrolyte TBAPF was carried out on ITO-coated glass electrode surface through continuous scanning of operating voltage. The produced novel polymer film’s electrochemical characterization was performed with cyclic voltammetry and chronoamperometry (CA) methods. The electrical conductivity of the polymer was measured by four-point conductivity method; the morphology of the polymer was analyzed by scanning electron microscopy (SEM). Spectroscopic analysis was carried out by FTIR spectroscopy and UV-Vis absorption spectroscopy. Some optoelectrochemical studies were done to investigate polymer film’s electrochromic properties. Optic contrast of the polymer film was found % 50 at 750 nm. Polymer conductivity was measured range of 1.83x10-3 S/cm. Polymer film’s color was close to dark orange when the polymer was reduced and color of the polymer film was dark blue tone while the polymer was oxidizing.

 

Bu çalışmada; yapısında pirol (Py) ve antrakinonu bir arada bulunduran yeni 1,5-(1-pirolil)-9,10-antrakinon monomeri sentezlenmiştir. Sentezlenen bu yeni monomerin yapısal karakterizasyonu Fourier Transform İnfrared Spektroskopisi (FTIR) ve 1H-NMR Spektroskopisi yöntemleriyle gerçekleştirilmiş,  elektrokimyasal davranışı ise dönüşümlü voltametri (CV) yöntemiyle incelenmiştir. 1,5-(1-pirolil)-9,10-antrakinon monomeri TBAPF destek elektroliti içeren nitrobenzen çözücü ortamında sürekli gerilim taraması yapılarak ITO (indiyum kalay oksit) kaplı cam elektrot yüzeyinde elektrokimyasal olarak polimerleştirilmiştir. Üretilen yeni polimer filmin elektrokimyasal karakterizasyonu dönüşümlü voltametri ve kronoamperometri (CA) yöntemleriyle gerçekleştirilmiştir. Polimer filmin iletkenliği dört nokta iletkenlik ölçüm yöntemi ile ölçülmüş, morfolojik yapısı Taramalı Elektron Mikroskopisi (SEM) ile incelenmiştir. FTIR spektroskopisi ve UV görünür bölge absorpsiyon spektroskopisi ile spektroskopik analizler yapılmıştır. Üretilen polimer filmin elektrokromik özelliklerinin incelenmesi amacıyla optokimyasal çalışmalar yapılmıştır. Polimer filmin optik zıtlığı 750 nm’de % 50 olarak bulunmuştur. Polimerin iletkenliği 1.83x10-3 S/cm olarak ölçülmüştür. Polimer filmin rengi yükseltgenme sırasında laciverte, indirgenme sırasında koyu turuncuya yakın renk almıştır.
