Triphenylamine (TPA) has been attracting great attention with its propeller-like structure, containing nitrogen atom in its center, and use in different fields, particularly in organic material chemistry [1]. It is widely used in electroluminescent materials, energy storage devices, organic dyes, charge transport materials, electrochromic materials, electroluminescences and organic solar cells. Thiophenes (Th) and thienothiophenes (TT) are also widely used building blocks in the construction of electronic and optoelectronic devices due to their, thermal stability, stable redox nature and high conductivity [2-4]. In recent studies, TT and TPA-based organic compounds have been reported to be suitable for various energy applications due to their low cost, wide-range of molecular designs, and tunable band properties. In this study, Th, TT and TPA based novel monomers were synthesized starting from 3-bromothiophene applying earlier methods developed by our group [5]. Then, optical and electrochemical properties of the new compounds were investigated. The resulting molecule seems to be a potential candidate for energy storage and many electronic and optoelectronic applications.
