Abstract
π-Conjugated pyrene–thiophene-based room-temperature discotic liquid crystals armed with four peripheral aliphatic chains are reported to study their potential use in a hole-transporting organic semiconductor. The charge carrier mobility studies using the ToF method revealed room temperature hole mobility in the order of 10−4 cm2 V−1 s−1 for both mesogens. However, the mobility values for compound 1a were observed in the order of 10−3 cm2 V−1 s−1 at high temperatures. Such molecular systems can potentially be used in nonlinear organic electronic applications. [ABSTRACT FROM AUTHOR]
