Special　asymmetric　crystallization　of　porous　framework　materials　from　achiral　precursors　under　urothermal　conditions　is　successfully　achieved　by　using　an　enantiopure　liquid　as　a　co-solvent　and　chirality　induction　agent,　which　provides　a　new　strategy　for　the　synthesis　of　homochiral　porous　materials　containing　only　achiral　building　blocks.
