Compared to linear acenes, only a few examples of peri-condensed organic semiconductors are known. Here, we report synthesis and charge transport properties of peri-condensed heteropyrenes in organic field effect transistors (OFETs). We show that 1,6-dioxapyrene derivatives are easily accessible and stable semiconductors that form well-ordered polycrystalline films, which results in moderately large hole mobility (ca. 0.25 cm(2) V(-1) s(-1)) in OFET devices.
