单晶三异丙基硅基乙炔基并五苯（TIPS-PEN）微带（见图）具有明确的刻面和前所未有的电气特性，如场效应迁移率高达1.4 cm（2）V-1 s（-1），是通过自组装的个别TIPS-PEN分子的结果，在溶液相中的疏溶剂相互作用，采用优先良好有序的分子间π-沿着带轴沿着堆叠π。
Single-crystalline triisopropylsilyl-ethynyl pentacene (TIPS-PEN) micro-ribbons (see figure) with well-defined facets and unprecedented electrical characteristics, such as a field-effect mobility as high as 1.4 cm(2) 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 pi-pi stacking along the ribbon axis.
