New anthracene-based X-shaped conjugated molecules and for use as highly soluble p-type organic semiconductors were developed and exhibited large field-effect mobilities of 0.04 cm(2) V(-1) s(-1) (I(on)/I(off) = 2.8 x 10(5)) and 0.24 cm(2) V(-1) s(-1) (I(on)/I(off) = 5.4 x 10(6)) for devices of and , respectively.
