Here　we　report　a　new　anion　conducting　covalent　organic　framework　(COF).　Quaternary　ammonium　(QA)　ions　are　covalently　tethered　onto　the　pore　walls　of　COF　1,3,5-triformylphloroglucinol-o-tolidine　(TpBD-Me)　through　bromination　and　quaternization.　The　QA-functionalized　COF　shows　a　bicarbonate　conductivity　of　5.3　mS　cm(-1)　at　20　degrees　C　and　27.0　mS　cm(-1)　at　80　degrees　C,　accompanied　by　3.3　wt%　water　uptake　and　＜1.0%　swelling　ratio　at　20　degrees　C.　This　QA-functionalized　COF　provides　a　new　option　for　anion　conducting　materials.
