A convenient and controlled organic semiconductor alignment strategy, superhydrophobic micropillar flowcoating (SMFC), is presented. Patterned, large-area (>1 cm(2)) 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene) single-crystalline arrays which show hole mobilities up to 6.8 cm(2) V-1 s(-1) were obtained via this method. Crucially, the polymorphism of TIPS-pentacene was regulated by tuning the flow rate, solvent and the substrate hydrophobicity. These results indicate that this technique is reliable for creating uniform and homogenous organic single-crystalline arrays with controlled crystal packing, thickness, and position.
