Pre-synthetic strategy to construct single ion conductive covalent organic frameworks

A Pre-synthetic strategy has been developed for the construction of a single ion conductive covalent organic frameworks (COFs). A high Li+ conductivity of 1.6×10-3 S cm-1 at 273 K was achieved and single Na+, K+ COFs were also obtained by using Na+ and K+ salts as monomers according to this synthetic method.
