Chiral　metal-organic　frameworks　(MOF)　composite　materials　hold　great　potential　for　circularly　polarized　luminescence　(CPL)　applications,　but　achieving　circularly　polarized　afterglow　remains　significant　challenging.　Herein　we　present　a　gel　transformation　fabrication　method　to　synthesize　carbon　nanodots　(CND)　incorporated　chiral　MOF　composite　films　with　circularly　polarized　afterglow.　A　chiral　amino　acid　based　MOF　gel　was　prepared,　combined　with　pre-synthesized　afterglow　CND　and　coated　onto　an　activated　quartz　substrate.　Annealing　and　drying　yielded　the　CND　incorporated　chiral　MOF　composite　film　(denoted　as　chirMOF-CND　film).　Due　to　the　strong　chiral　transfer　and　synergistic　interaction　with　gapless　connection　between　the　components　of　chiral　MOF　film　and　the　afterglow　luminophores　of　CND,　the　chiral　composite　film　achieves　high-performance　circularly　polarized　afterglow.　Additionally,　the　afterglow　duration　can　be　modulated　by　varying　the　CND　concentration.　This　gel　transformation　strategy　utilizes　the　unique　attributes　of　chiral　MOF　and　the　persistent　luminescence　of　CND　for　fabricating　chiral　composite　monoliths　with　seamless　integration,　advancing　next-generation　optical　devices　and　sensors　applications.　©　The　Author(s)　2025.
