Nanoporous polymer film with a hexagonal columnar (Col_h) structure was fabricated by templated hydrogen-bonding discotic liquid crystals containing methacrylate functional group. The supramolecular hydrogen-bonded complex T3Ph-L is composed of a 1,3,5-tris(1H-benzo[d]imidazol-2-yl)benzene (T3Ph) core molecule as the hydrogen-bonding acceptor and 3,4,5-tris((11-(methacryloyloxy)undecyl)oxy)benzoic acid (L) peripheral molecules as donors. And the Col_h structure is always retained after self-assembly, photo-crosslinking, and removal of the template T3Ph. The nanoporous polymer film can retain the Col_h phase even under the dry condition, which indicates more possibilities for practical applications. After chemical modification of the inner wall of the nanopores, the nanoporous polymer film with pores of about 1 nm selectively adsorbs ionic dyes, and the adsorption process is spontaneous and exothermic in nature. Homeotropic alignment can be obtained when the blend complex was sandwiched between two modified glasses after annealing by slow cooling, which shows that the nanoporous polymer film has potential in applications such as nanofiltration.

通过模板化氢键合含甲基丙烯酸酯官能团的盘状液晶，制备了具有六方柱状（Col _h）结构的纳米多孔聚合物膜。超分子氢键复合物T3Ph-L由1,3,5-三（1 H-苯并[ d ]咪唑-2-基）苯（T3Ph）核分子作为氢键受体和3,4组成，5-三（（11-（甲基丙烯酰氧基）十一烷基）氧基）苯甲酸（L）外围分子作为供体。自组装，光交联和除去模板T3Ph后，始终保留Col _h结构。纳米多孔聚合物膜可以保留Col _h即使在干燥条件下也能保持稳定，这表明在实际应用中有更多的可能性。在对纳米孔的内壁进行化学修饰之后，具有约1nm的孔的纳米多孔聚合物膜选择性地吸附离子染料，并且吸附过程本质上是自发的且放热的。当通过缓慢冷却将共混物复合物夹在两块改性玻璃之间进行退火后，可以实现垂直排列，这表明纳米多孔聚合物膜在诸如纳滤等应用中具有潜力。
