AB  - Multiple microenvironmental modulation of zeolite imidazole framework-8 (ZIF-8) 
      is expected to solve the long-term intractable problem of low sensitivity in 
      electrochemical sensing. Herein, the metal phthalocyanines with different central 
      ions (PcM, M = Fe, Co, Ni and Cu) were introduced into ZIF-8 by in-situ synthesis 
      method. Then, the hollow composite nanomaterials, HZIF-8/PcFe and HZIF-8@PcFe 
      (HZIF-8, i.e., hollow ZIF-8) with different TA (tannic acid) coating thicknesses 
      ( approximately 11 nm and  approximately 33 nm) were successfully fabricated by carefully designed 
      polyphenol-mediated modulation (PMM) strategy. Next, the HZIF-8@PcFe 
      electrochemical sensor was constructed for selective and sensitive analysis by 
      selecting dopamine (DA) as the analyte. The TA coating (superhydrophilic state), 
      PcFe (redox properties) and hollow MOF cavity (faster mass transfer) was used as 
      the triple microenvironment modulation of ZIF-8 to enhance the electrocatalytic 
      performance. Under the optimum conditions (pH = 8.0), the linear correlations of 
      0.3 to 200 mumol/L was obtained for the peak current response, with a detection 
      limit of 0.1 mumol/L (S/N = 3, i.e., Signal/Noise = 3). Meanwhile, the HZIF-8@PcFe 
      electrochemical sensor exhibited excellent interference selectivity, 
      reproducibility and stability, which enabled it to detect low abundance DA in 
      real samples. And the F-test (homogeneity test of variance) and t-test (student's 
      t test) statistical analyses were employed to enhance the accuracy of the actual 
      samples' detection. This work will enlighten researchers working in the field of 
      porous framework composites and open up new paths for the development of hollow 
      MOFs hybrid materials in electrochemical sensing.
