The host-guest complexation between a porphyrin-based 3D tetragonal prism (H) and electron-rich pyrene is investigated. This host-guest molecular recognition is further utilized to suppress the liquid-crystalline behavior of a nematic molecule (G) containing cyanobiphenyl mesogens functionalized with a pyrenyl unit. Furthermore, coronene, with an increased number of π-electrons, is used as a competitive guest to recover the liquid-crystalline behavior of G. This supramolecular approach provides a glimpse of the new possibilities to modulate the structures of the mesophases.
研究了基于卟啉的三维四方棱柱（主体H）与富电子芘之间的主客体络合作用。这种主客体分子识别进一步用于抑制含有芘基单元官能化的氰基联苯液晶元的向列型分子（客体G）的液晶行为。此外，具有更多π电子的蒄用作竞争性客体以恢复G的液晶行为。这种超分子方法为调节中间相结构的新可能性提供了一些线索。
