- Abstract
- We report here, synthesis, physical, thermal, and optoelectronic properties of compounds containing anthracene, anthraquinone, and 11,11,12,12-tetracyano-9,10-anthraquinodimethane units connected to quaterthiophene units. Three compounds, TQAO (6), TQAN (7), and TQAM (8) are synthesized by using Stille coupling, reduction, and Knoevenagel condensation reactions. These compounds were thermally stable and exhibited organic thin-film transistor (OTFT) properties. Among them, TQAM (8)-based OTFT has shown ambipolar mobility, both hole and electron mobility of 2.0 x 10(-6) and 2.43 x 10(-7) cm(2)/Vs, respectively. TQAO (6) and TQAN (7) has shown low electron mobility of 5.58 x 10(-6) and 1.22 x 10(-5) cm(2)/Vs, respectively.
