Abstract：Metal-organic cages（MOCs）are discrete supramolecular architectures formed through the coordinationdriven self-assembly of metal ions and organic ligands.These structures have garnered significant atentionowing to their tunable geometries，diversecavityconfigurations，and facile functionalizationcapabilities.Inrecent years，the rapidadvancementof aggregation-induced emision（AIE）materials，along with theirdistinctiveadvantages inluminescence mechanisms and functionaldesign，has offerednovelinsightsand opportunities forthedevelopment of innovativeMOCs.This article provides an overviewof the most recent advancements inthe synthetic strategies for MOCs exhibiting AIE properties，with particular emphasisontheconstructionof AIE-active MOCs through thecoordinationdriven self-assembly of AIE chromophores，such as tetraphenylethylene（TPE）and carbazole，with center metals including Pt（II），Zn（II），Pd（II），and Cd（II）.This class ofcompounds demonstrates not only superioroptical propertiesbut also extensiveapplication potential acrossvarious advanced fields，including bioimaging，chemical and biological sensing，information storage and encryption，and light-harvesting systems.
