Preparation method and application of alpha-tropine-based non-arylether polyfluorene alkylene polymer and anion exchange membrane

The invention discloses a preparation method and application of an alpha-tropine-based non-arylether polyfluorene alkylene polymer and an anion exchange membrane, and belongs to the technical field of organic synthesis and energy conversion. According to the invention, a non-arylether polyfluorene alkylene polymer containing a side chain terminal bromine group is obtained by utilizing a superacid catalyzed Friedel-Crafts alkylation reaction, and further, the terminal bromine of the polymer and steric hindrance cage-shaped alpha-tropine containing a tertiary amine group are subjected to a Moshu reaction to obtain the non-arylether polyfluorene alkylene anion exchange polymer containing cage-shaped tropine quaternary ammonium salt. The position of the cation group of the anion exchange membrane prepared from the polymer is controllable, and the density of the ion group can be improved. Meanwhile, the caged large-steric-hindrance tropine quaternary ammonium salt ensures the chemical stability, and the contained hydrophilic hydroxyl can promote water transmission and ion conduction in the membrane. A hydrophobic polymer skeleton is separated from hydrophilic tropine through a long alkyl side chain linker, so that the polymer has an obvious microphase separation structure, and generation of OH <-> transport ion channels is promoted. The non-aryl ether polymer main chain and the hydroxyl-containing cage sterically hindered cations can ensure that the anion exchange membrane prepared from the polymer has long-term alkali-resistant stability.
