Despite　of　great　efforts　to　explore　more　luminophores　and　to　further　faster　the　reaction　kinetics　by　adding　additional　co-accelerant　in　electrochemiluminescence　(ECL)　system,　it　is　still　crucial　to　find　new　ways　to　improve　their　luminous　efficacy.　Here,　a　skillful　ligand　exchange　strategy　was　designed　to　prepare　new　porphyrinlanthanide　composite　material　UiO-THPP　(THPP　=　tetrahydroxyphenylporphyrin)　with　integrated　emitter　and　reaction　accelerator　function.　The　rationally　regulated　nanoflower-like　morphology　of　the　Cu-doped　MOF　CeUiO-66-NH2　(Cu:Ce　=　2:1)　could　load　more　reactive　intermediates,　shorten　the　electron　transport　distance　and　exhibit　satisfactory　ECL　strength.　Due　to　the　effective　signal　amplification　strategy　of　＂antenna　effect＂　from　porphyrin　to　Ce4+　and　also　with　the　help　of　the　catalytic　Ag　NPs,　the　ECL　intensity　of　UiO-THPP　was　further　significantly　increased.　More　importantly,　the　tailored　material　by　integrating　the　co-interacting　accelerator　and　the　luminescent　emitter　through　ligand　exchange　strategy　showed　obviously　improved　electron　transfer　efficiency　and　reaction　speed.　As　expected,　the　proposed　ECL　aptamer　sensor　demonstrated　favorable　detection　performance　for　kanamycin　within　10　fg/mL-1000　ng/mL　and　gave　the　detection　limit　as　low　as　4.2　fg/mL.　This　work　provided　valuable　information　for　the　rational　design　of　a　self-enhanced　ECL　system　with　simple　procedure,　composition　and,　however,　the　excellent　bifunctional　luminescence　and　coreaction　acceralation　property.
