Description

technical field [0001] The invention belongs to the field of macromolecular polymers, and more specifically relates to an anthracene main chain self-porous polymer, a synthesis method and application thereof. Background technique [0002] The self-porous polymer inhibits the free rotation of the chain conformation in space by constructing a polymer chain combining rigidity and twisted structure, and the introduction of the twisted structure makes it difficult for the polymer chain to be regular in space stacking, resulting in holes or larger free volume. Compared with three-dimensional framework porous materials, self-porous polymers have both high specific surface area and processability, making them have significant applications in membrane separation, catalysis and other fields and have attracted much attention. [0003] At present, the synthesis methods of self-porous polymers mainly include nucleophilic substitution reaction (P.M.Budd et al.Chem.Commun.2004,230) and Ch...
