A stabilization of the liquid-crystalline mesophase and thus an enlarged temperature range of the mesogenic phase is achieved by adding perfluorotriphenylene to a chiral liquid-crystalline triphenylene. This mesophase is based on 1:1 perfluoroarene-arene interactions (see picture). In a polymer with triphenylenes as mesogens in the side chains, the addition of perfluorotriphenylene led to crystallization.
通过向手性液晶三亚苯中添加全氟三亚苯，实现了液晶中间相的稳定，从而扩大了介晶相的温度范围。这种中间相基于1:1的全氟芳烃 - 芳烃相互作用（见图）。在侧链中以三亚苯作为介晶元的聚合物中，添加全氟三亚苯会导致结晶。
