A novel phenylacetylene monomer having a perfluorinated alkyl group (M-F) was synthesized and polymerized in a chiral catalytic system to yield a one-handed helical polymer. The ability and efficiency of the chiral induction of the fluorine-containing monomer in the helix-sense-selective polymerization (HSSP) was much higher than those of a monomer having the corresponding alkyl group (M-H) we reported before. The resulting polymer showed cis-cisoidal one-handed helical conformation, and was suitable for highly selective photocyclic aromatization (SCAT) to give a 2D surface modifier (). Oxygen permselectivity through a base polymer membrane was highly enhanced from 1.83 to 2.36 by adding a small amount (1-5 wt%) of the 2D surface modifier . The improvement was thought to be caused by improvement of solution selectivity on the membrane surface which the 2D surface modifier effectively covered.
合成了一种具有全氟烷基的新型苯乙炔单体（M-F），并在手性催化体系中进行聚合，得到了单手螺旋聚合物。含氟单体在螺旋方向选择性聚合（HSSP）中的手性诱导能力和效率远高于我们之前报道的具有相应烷基的单体（M-H）。所得聚合物呈现顺式-顺oidal单手螺旋构象，适用于高选择性光环化芳构化（SCAT）以得到二维表面改性剂（）。通过添加少量（1-5 wt%）的二维表面改性剂，基础聚合物膜的透氧选择性从1.83显著提高到2.36。这种改善被认为是由于二维表面改性剂有效覆盖的膜表面溶液选择性提高所致。
