通过离子自组装的方法，将两种不同的匹配阴离子，即光敏单元甲基橙子（MO）和全氟十二烷酸（FDA）连接到聚离子液体（PIL）主链上，制备了光敏配合物.红外光谱证明，这两种阴离子竞争性地连接到PIL主链上。配合物显示出典型的液晶行为，并具有单层层状介观结构的PMOF0。FDA的掺入导致流延膜中出现不同的片层结构，具体取决于FDA含量：当FDA含量增加到10%时，MO和FDA侧链独立地组织成不同的片层结构：根据XRD研究，MO片层结构有利于单层堆积顺序，FDA有利于双层堆积顺序。这些复合物在控制液晶分子的面内和面外取向方面是有效的。
Through an ionic self-assembly approach, a photosensitive complex was prepared by attaching two different matching anions, photoresponsive units of methyl orange (MO) and perfluorinated dodecanoic acid (FDA), to a poly(ionic liquid) backbone (PIL). The FTIR spectrum proved that the two anions were competitively attached to the PIL backbone. The complexes show typical liquid crystalline behavior and have a single layer lamellar mesostructure for PMOF0. The incorporation of FDA leads to different lamellar structures in casting film depending on the FDA content: when the FDA content increases to 10%, MO and FDA side chains organized into a different lamellar structure independently: MO lamellar structure favors single layer packing order and FDA favors bi-layer packing order according to XRD investigation. These complexes are effective in controlling the in-plane and out-of-plane alignment of liquid crystal molecules.
