By selecting a preferred solvent to ensure good wettability of 6,13‐bis(triisopropylsilylethynyl)‐pentacene (TIPS‐pentacene) solution on both hydrophobic and hydrophilic dielectrics, the highly ordered TIPS‐pentacene microwire arrays are successfully obtained. The highest mobility of TIPS‐pentacene organic field‐effect transistors (OFETs) on divinyltetramethyldisiloxane‐bis(benzocyclobutene) (BCB)/SiO 2 is ascribed to the matching of both the polar and dispersive components of surface energy between dielectric and semiconductor.
