Owing to the environmental stability, high charge carrier mobility, low cost, and flexibility, thiophene (Th)-based πconjugated materials which are easy to modification for fine tuning the electronic properties have been holding a particular interest [1-2]. Thieno[3,2-b]thiophenes (TT) play an important role as their core skeleton consists of two fused rigid Th rings to limit the rotational disorder between the rings and create a better π-conjugation. Due to electron-rich structures, TT and derivatives could be employed for
adjusting the band gap of organic materials [3] and in recent studies it is reported that their polymer films were found to be
suitable for electronic and optoelectronic applications [4-6]. Triphenylamine (TPA) has become a valuable unit for wide
range of materials such as OLEDs, solar cells, sensors, capacitors, and hole-transport devices, due to major
properties of low-cost, large range of molecular designs and good hole mobilities, excellent thermal stability, high
ionization potential
