Abstract

New anthracene-based X-shaped conjugated molecules 1 and 2 for use as highly soluble p-type organic semiconductors were developed and exhibited large field-effect mobilities of 0.04 cm²V⁻¹ s⁻¹ (I_on/I_off = 2.8 × 10⁵) and 0.24 cm²V⁻¹ s⁻¹ (I_on/I_off = 5.4 × 10⁶) for devices of 1 and 2, respectively.
