Copper　halide　clusters　have　become　one　of　the　most　prosperous　cluster-based　materials.　They　are　not　only　widely　used　in　the　fields　of　photophysics　and　photochemistry,　but　also　adsorption,　catalysis,　biology,　etc.　Herein,　the　recent　progress　in　copper　halide　based　chemistry　is　reviewed　from　three　aspects.　In　the　first　place,　we　summarize　the　new　synthesis　strategies　promoting　the　crystallization　of　copper　halide　cluster-based　materials.　Then,　the　structural　diversity　of　the　compounds　is　introduced　according　to　the　dimension　of　copper　halogen　clusters.　Finally,　we　discuss　the　functionality　of　copper　halide　cluster-based　materials　including　optical,　catalytic　and　adsorption　properties.　In　addition,　perspectives　on　their　potential　applications　are　presented.
