[1]Benzothieno[3,2-b][1]benzothiophene (BTBT) is a promising molecule that attracts interest of researchers due to its excellent electrical performance [1-3]. Consecutive fused aromatic rings and sulfur atoms give BTBT an extensive conjugated system. Such a specific structure gives adequate spatial distribution of highest occupied molecular orbital (HOMO) for effective π-orbital overlap, leading to highly efficient charge carrier transport. In addition, large band gap (> 3 eV) of BTBT compounds has been known to afford high air-stability [4]. BTBT shows high electrical properties both in the composition of low molecular weight semiconductors and in the composition of polymer semiconductors. Recently, we developed various BTBT-based devices that show good charge mobility in different applications [5-7]. We assume that special individual mechanical and morphological characteristics of polymers functionalized with BTBT are important for producing various flexible electronic devices with high electric properties. Apart from it, such frameworks are manufacturable and low cost meaning they are essential in producing a large area electronics.
