Metal-organic　frameworks　(MOFs)　refer　to　novel　crystalline　porous　materials　constructed　by　linking　metal　nodes　and　organic　linkers　through　coordination　bonds.　Featuring　predictable　and　designable　long-range　ordered　structures,　high　surface　areas,　guest-accessible　voids,　and　easily　functionalized　channels　by　pre-　or　post-modifications,　MOFs　have　attracted　much　attention　in　the　past　two　decades.　In　this　review,　we　discussed　the　design　strategies,　synthesis　methods,　and　structural　characteristics　of　MOFs　and　MOF-derived/composite　materials.　Meanwhile,　the　challenges　facing　MOF　research　were　also　discussed.
