AB  - Trace amount of H(2)O is difficult to eliminate in laboratory environments and 
      chemical industries as impurities. In some chemical reactions, trace amount of 
      H(2)O can alter final reaction products, yield, and selectivity. So, the 
      detection of trace H(2)O is very important. Herein, a series of TFPT([X])-BMTH- 
      covalent organic frameworks (COFs) (X = 0, 33, 50, 67, 100 %) with intramolecular 
      charge transfer effect (ICT) and aggregate-induced emission (AIE) characteristics 
      were synthesized by amino-aldehyde condensation reaction between 
      2,5-bis(2-methoxyethoxy)terephthalohydrazide (BMTH)/ 
      1,3,5-tris(p-formylphenyl)benzene (TFPB) and 
      4,4',4''-(1,3,5-triazine-2,4,6-triyl)tribenzaldehyde (TFPT). By changing TFPT' 
      content in TFPT([X])-BMTH-COFs, the ICT and AIE of TFPT([X])-BMTH-COFs can be 
      controlled, and accordingly the response to trace H(2)O can be adjusted. A H(2)O 
      sensor based on TFPT([67])-BMTH-COF with a wide linear range from 0 wt% to 
      0.5 wt% was developed and the detection limit was 0.00007 wt%. In addition, a 
      portable fluorescent test paper based on TFPT([67])-BMTH-COF for visual detection 
      of trace H(2)O in honey samples and salt was constructed. This work has important 
      guiding significance for the development of fluorescent probes for the visual 
      detection of trace water.
