Poly(phenylene)-based anion exchange membrane

摘要

A poly(phenylene) compound of copolymers that can be prepared with either random or multiblock structures where a first polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 2 pendant phenyl groups and 4 pendant tolyl groups and the second polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 6 pendant phenyl groups. The second polymer has chemical groups attached to some of the pendant phenyl groups selected from CH₃, CH₂Br, and CH₂N(CH₃)₃Br groups. When at least one group is CH₂N(CH₃)₃Br, the material functions as an anion exchange membrane.
