Luminescent　supramolecular　metallacycles　have　attractedgreat　interestas　a　new　promising　class　of　sensing　substrates.　In　this　work,　twotetraphenylethene　(TPE)-based　diimidazole　and　dipyrazole　ligands　withthe　aggregation-induced　emission　(AIE)　feature　were　designed　for　theconstruction　of　supramolecular　tetragonal　metallacycles　1-4　with　two　90　&　DEG;　mononuclear　[(bpy)M](2+)　or　dinuclear　[(bpy)(2)M-2](4+)　acceptors　(bpy　=　2,2　&　PRIME;-dipyridine;　M　=　Pd,　Pt),　in　which　thefluorescence　can　be　quenched　to　an　＂off＂　state　due　tothe　ligand-to-metal　charge　transfer　(LMCT).　Metallacycle　1　was　utilized　as　a　fluorescence　sensor　for　phosphate　(PO4　(3-))　detection　in　aqueous　solution　by　means　of　disassembly,leading　to　the　release　of　the　ligand.　Additionally,　the　metallacyclecan　be　regenerated　through　self-assembly　via　the　introduction　of　Pd(II)acceptors.　PO4　(3-)　was　detected　using　TPE-basedmetallacycles　over　a　wide　concentration　range,　with　a　detection　limitas　low　as　2.1　x　10(-8)　M.　Furthermore,　sensor　1　also　presented　the　semiquantitative　visual　detection　abilityfor　PO4　(3-)　in　the　test　paper　mode　viafluorescence　changes.　The　aforementioned　studies　not　only　enhancethe　current　research　on　fluorescent　materials　but　also　offer　a　strategyfor　the　creation　of　stimuli-responsive　supramolecular　coordinationcomplexes.
