In organic electronics the functionalization of dielectric substrates with self-assembled monolayers is regarded as an effective surface modification strategy that may significantly improve the resulting device performance. However, this technique is not suitable for polymer substrates typically used in flexible electronics. Here, we report organic modifiers based on a paraffinic tripodal triptycene, which self-assembles into a completely oriented two-dimensional hexagonal triptycene array and one-dimensional layer stacking structure on polymer surfaces. Such few-layer films are analogous to conventional self-assembled monolayers on inorganic substrates in that they neutralize the polymer surface. Furthermore, the triptycene films significantly improve the crystallinity of an organic semiconductor and the overall performance of organic thin-film transistors, therefore enabling the fabrication of high-performance organic complementary circuits on polymer substrates with high oscillation speeds and low operation voltage.

在有机电子学中，具有自组装单层的介电基板的功能化被认为是一种有效的表面改性策略，可以显着提高所得器件的性能。但是，该技术不适用于柔性电子设备中通常使用的聚合物基材。在这里，我们报告基于链烷烃三脚架三烯的有机改性剂，其自组装成完全定向的二维六边形三烯阵列和聚合物表面上的一维层堆叠结构。这种多层膜与无机基材上的常规自组装单层膜相似，因为它们会中和聚合物表面。此外，
