Molecular design of star-shaped benzotrithiophene materials for organic electronics

Progresses in the design and application of conjugated small molecules, oligomers and polymers haveempowered rapid development of organic electronic technology as an alternative to conventionaldevices. Among the numerous organic electronic materials, benzotrithiophene (BTT)-based oligomersand polymers have recently come in the limelight demonstrating great potential in organic electronicsas high performance photovoltaic devices, field-effect transistors, electrochromic materials, high-areacapacitors and charge carrier discotic liquid crystals. In this digest, we propose an overview of the organicelectronic materials based on BTT isomers, highlighting the structure-performance relationship. Theresults obtained so far clearly indicate that the BTT isomers are among the most promising buildingblocks for the developmentp-extended materials for optoelectronic applications in the near future.
