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.
