[1]Benzothieno[3,2-b][1]benzothiophene (BTBT) attracts lots of researchers in organic electronics due to its highly efficient performance, air-s and thermal stability. BTBT is a π-conjugated molecule caused by it heteroaromatic backbone. Most of π-conjugated polymers are used to produce organic field-effect transistors (OFET), electrochromic devices(1), chemo- and biosensors(2,3), semiconductor lasers(4), photovoltaic cells and photodiodes(5), supercapacitors(6), etc. Polymers in organic electronics make it easier to produce large area flexible electronic devices because of low cost and manufacturability. Recently, we developed various BTBT-based devices that show good charge mobility in different applications(7,8,9). In this work the idea of producing BTBT polymer takes place. We report on a synthesis of a range of polymers functionalized with BTBT-derivatives (Fig.1) and show their properties. 1. Dimitrakopoulos, C.D.
