设计并合成了笼型倍半硅氧烷（POSS）与六-正-六苯并蔻（HBC）的杂化物，该杂化物具有哑铃型拓扑结构和C2对称性.它们自组装成5 nm有序结构。 特别地，随着POSS单元的增加而增加的空间效应稳定了在纳米模板中重要的方形柱状相（Colsquare phase）。这些混合物含有dispersed液晶HBC和POSS单元具有优异的蚀刻对比度，并提出了一种方法，以获得5 nm的纳米片。
Hybrids consisting of polyhedral oligomeric silsesquioxane (POSS) and hexa‐peri‐hexabenzocoronene (HBC) with a dumbbell topology and C2symmetry were designed and synthesized. They self‐assemble into 5 nm ordered structures. In particular, the increased steric effect with increasing POSS units stabilizes a square columnar phase (Colsqu) which is important in nanotemplating. These hybrids containing discotic liquid crystal HBC and POSS units have an excellent etching contrast and present an approach to obtain 5 nm nanopatterns.
