合成了一系列含低聚二甲基硅氧烷的四苯基卟啉基热致液晶。这些盘-线圈混合物形成有序的纳米结构，其周期性尺寸在5 nm以下，包括斜柱状相、层状相和六方柱状相。通过衬底诱导自组装可以获得具有亚5 nm线图案和垂直排列的柱状结构的薄膜。
A series of tetraphenylporphyrin-based thermotropic liquid crystals containing oligo(dimethylsiloxane) were synthesized. These disc-coil hybrids form ordered nanostructures with periodic sizes on the sub-5 nm scale, including oblique columnar, lamellar, and hexagonal columnar phases. Films with sub-5 nm line patterns and homeotropically aligned columnar structures can be obtained by substrate-induced self-assembly.
