Synthesis of conjugated organic molecules having electronic and optical properties suitable for electrochromic devices (ECD), organic light emitting diode (OLED), organic field effective transistors (OFET), lasers, photodiodes and solar cell applications have gained importance in recent years.1-3 Based on the previous studies on thienothiophenes (TT),2,3  new donor-acceptor materials,4-[5-[bis-(2,4,6-trimethyl-phenyl)-boranyl]-2-(4-diphenylamino-phenyl)-thieno[3,2-b]thiophen-3-yl]-benzonitrile containing π-conjugated system and having electron withdrawing cyano group and acceptor boron4 were designed and synthesized. Its electronic and optical properties were investigated. It has been found to be suitable for OLED applications.
