A novel wedge-shaped amphiphilic molecule bearing a sulfonate group at the tip displays humidity-induced phase transitions from a hexagonal columnar structure to a bicontinuous cubic phase. The mesophases can be frozen by photopolymerization of acrylic end-groups resulting in free-standing membranes with different topology of ionic nanochannels. The obtained membranes with a well-ordered ionic channel structure hold promise for applications in separation and catalysis.
一种新型楔形两亲分子，在其尖端带有磺酸基团，在湿度诱导下从六方柱状结构向双连续立方相转变。通过末端丙烯酸基团的光聚合，可以将中间相冷冻，得到具有不同拓扑结构的离子纳米通道的独立膜。具有有序离子通道结构的所得膜有望在分离和催化中得到应用。
