Cation–π induced lithium-doped conjugated microporous polymer with remarkable hydrogen storage performance

Abstract

A cation–π induced lithium-doped conjugated microporous polymer, Li⁺–PTAT, was constructed. It was proved that the point to face cation–π interactions between Li⁺ and indole can endow the resulting Li⁺–PTAT with high Li⁺ content and without agglomeration, which further leads to its encouraging hydrogen storage capacity.
