Patterning on the sub‐5 nm length scale is a contemporary challenge for further miniaturization of microelectronic circuits. Here, the first soft self‐assembled triangular patterns are reported showing transitions between regular and two different kinds of isosceles (acute and obtuse angled) triangles on this length scale, formed by liquid crystalline honeycombs of polyphilic block molecules involving a fluorinated oligo(para‐phenylene ethynylene) core. The type of formed triangular pattern depends on the degree and position of fluorination and on temperature. They are the first soft honeycombs combining tilted and nontilted organizations in a uniform nanostructure, where the tilted molecules in only one or two sides of the triangular prismatic cells dominate the shape and the size of the morphology.

5纳米以下的软三角蜂窝的不同变形模式

在亚5纳米长度范围内进行图案化是微电子电路进一步小型化的当代挑战。这里，第一软自组装三角形图案报告显示在该长度尺度规则和两种不同类型的等腰的（急性和钝角）三角形之间的转变，通过涉及氟化低聚（polyphilic块分子的液晶蜂窝形成对位亚苯基亚乙炔基）芯。形成的三角形图案的类型取决于氟化的程度和位置以及温度。它们是第一批将倾斜和非倾斜组织结合成均匀纳米结构的软蜂窝，其中三角形棱柱形细胞的仅一侧或两侧的倾斜分子主导着形态的形状和大小。
