AB  - Due to the ultra-weak and instantaneous chemiluminescence (CL) of 
      luminol-H(2)O(2) system, developing new catalysts to dramatically enhance and 
      produce persistent CL emission is crucial. In this study, the Cu-metal-organic 
      frameworks (Cu-MOFs) with flower morphology converted from Cu-based metal-organic 
      gels (Cu-MOGs) could catalyze luminol-H(2)O(2) system, exhibiting persistent CL. 
      The possible mechanism of this persistent emission of luminol was attributed to 
      the gradual generation of OH , O(2) (-) and (1)O(2) in Cu-MOFs-catalyzed 
      luminol-H(2)O(2) system. In addition, OH  and O(2) - were continuously recombined 
      into singlet oxygen on the surface of Cu-MOFs which further prolonged the 
      duration time of the CL leading to the persistent emission, due to the longer 
      lifetime of (1)O(2) compared to OH  and O(2) (-). Furthermore, based on the 
      high-intensity emission of Cu-MOFs-catalyzed luminol-H(2)O(2) system, the 
      strategy for sensitive response to quercetin was established with good linearity 
      within the range of 0.05-1.2 muM and a detection limit of 49.7 nM. This study 
      provides a new idea for developing persistent CL catalysts.
