Single-crystalline triisopropylsilylethynyl pentacene (TIPS-PEN) microribbons (see figure) with well-defined facets and unprecedented electrical characteristics, such as a field-effect mobility as high as 1.4 cm2 V–1 s–1, are fabricated through the self-assembly of individual TIPS-PEN molecules as a result of solvophobic interactions in the solution phase adopting preferential well-ordered intermolecular π–π stacking along the ribbon axis.
