To develop a new phenylacetylene monomer suitable for helix-sense-selective polymerization (HSSP) we reported previously and to improve the efficiency of the HSSP and membrane performance of the resulting polymer, a novel phenylacetylene having a trisiloxanyl group (S3BDHPA) was synthesized and polymerized by using a chiral catalytic system and enantioselectivity in permeation of its membrane was examined
为了开发一种我们先前报道的适合于螺旋正义选择性聚合(HSSP)的新型苯基乙炔单体,并为了提高HSSP的效率和所得聚合物的膜性能,合成了一种具有三硅氧烷基的新型苯基乙炔(S3BDHPA)并进行了聚合。通过使用手性催化体系和对映体在其膜渗透中的选择性进行了研究。S3BDHPA适用于HSSP,并且聚(S3BDHPA)的CD吸收比相应的不含硅氧烷基的聚合物更强,更稳定。另外,聚(S3BDHPA)的渗透对映选择性比不具有硅氧烷基的聚合物膜的对映选择性高得多。它们被认为是由三硅氧烷基团的柔韧性和疏水性引起的。
