  Facile synthesis of five 2D surface modifiers by highly selective photocyclic aromatization and efficient enhancement of oxygen permselectivities of three polymer membranes by surface modification using a small amount of the 2D surface modifiers

  摘要：

  A facile synthesis of novel five 2D (planar) surface modifiers having a triphenylbenzene derivatives as a 2D structure has been achieved by the highly selective photocyclic aromatization reaction. Efficient enhancement of oxygen permselectivities through the three polymer membranes has been achieved by adding a small amount (< 5.0 wt%) of the 20 surface modifiers. Among the five 2D surface modifiers, a modifier compound having oligoethylene oxide groups showed the best performance for the enhancement. These improvements were thought to be caused mainly by improvement of the solution selectivity on the membrane surface where the 2D surface modifiers were accumulated. In some of the surface-modified blend membranes, their plots in the P-O2(-alpha) graph were over or close to the upper boundary line by Robeson in 1991. Since all the membranes containing the 2D surface modifiers showed better permselectivities than the corresponding substrate membranes, it is very promising for the future. (C) 2013 Elsevier Ltd.

  A novel achiral phenylacetylene having a bulky t-butyl group was synthesized and polymerized by a chiral catalytic system containing [Rh(nbd)Cl]2 (nbd: norbornadiene) and chiral amines to yield a one-handed helical polymer having a much higher g value than polymers with no bulky groups. Highly efficient helix-sense-selective polymerization has been achieved using a bulky monomer and a less bulky chiral cocatalyst.

  合成了一种新型非手性苯乙炔，该苯乙炔带有一个笨重的 t-丁基，通过含有 [Rh(nbd)Cl]2 （nbd：降冰片二烯）和手性胺的手性催化体系进行聚合，得到了一种单手螺旋聚合物，其 g 值远远高于不含笨重基团的聚合物。利用笨重的单体和笨重程度较低的手性助催化剂，实现了高效的螺旋感应选择性聚合。
