Triazin Bazlı Karbazol Türevi ile 2,3-Etilendioksi Tiyofenin Kopolimerleştirilmesi ve Elektrokromik Özelliklerinin İncelenmesi

Kopolimerizasyon polimer kimyasında iki farklı monomerin polimer özelliklerinin birleştirilerek son ürünün optik, mekanik ve elektriksel özelliklerinin istenen seviyeye çıkarılması için sıklıkla kullanılan bir tekniktir. Bu amaçla birbirinden farklı özelliklere sahip iki monomer birlikte polimerleştirilmesiyle sinerjik etki ile her iki monomerin homopolimerlerinden daha üstün özelliklerde kopolimer elde edilir. Bu çalışmada iletken polimerler sentezinde yaygın olarak kullanılan 2,3 etilen dioksitiyofen (EDOT) ile yine üstün özelliklere sahip sentezlediğimiz triazin bazlı karbazol türevi monomer (TPC) ile kopolimerleştirme yapılmıştır. Bu kopolimer çalışmadaki ana motivasyon kopolimerleştirmede kullanılacak monomerlerden elde edilen homopolimerlerin zıt redoks hallerinde şeffaf ve renkli olmalarıdır. Bu iki monomerin birlikte polimerleştirilmesi ile elde edilen kopolimerin literatürde pek sık karşılaşılmayan siyah elektrokromik özellik gösterdiği saptanmıştır. Ayrıca elde edilen bu özgün kopolimerin optik ve elektriksel özellikleri dönüşümlü voltametri, spektroelektrokimya vb tekniklerle karakterize edilerek optik ve elektriksel özellikleri incelenmiştir

Copolymerization of 2,3-Ethylenedioxy Thiophene with Triazine-Based Carbazole Derivative and Investigation of Its Electrochromic Properties

Copolymerization is a unique technique frequently used to combine the polymer properties of two different monomers in polymer chemistry to bring the optical, mechanical and electrical properties of the final product to the desired level. For this purpose, two monomers with different properties are polymerized together to obtain a synergistic effect and obtained copolymer have superior properties then homopolymers of both monomers. In this study, copolymerization was carried out with triazinebased carbazole derivative monomer (TPC) which has superior properties and 2,3-ethylene dioxythiophene (EDOT) which is widely used in the synthesis of conductive polymers. The main motivation in this copolymer work is that the homopolymers obtained from the monomers to be used in the copolymerization are transparent and colored in the opposite redox state. The copolymer obtained by copolymerization of these two monomers has been found to exhibit black electrochromic properties which are rarely encountered in the literature. In addition, the optical and electrical properties spectroelectrochemistry, etc., and their optical and electrical properties were investigated. of this unique copolymer were characterized by cyclic voltammetry
