AB  - The aggregation-induced emission (AIE) luminogens are now showing strong 
      potential in mimicking the energy donor of fluorescence resonance energy transfer 
      (FRET) system. Herein, one highly efficient FRET system 1-NiR is successfully 
      fabricated in aqueous solution based on an AIE active compound 1 and fluorescence 
      dyes (Nile red (NiR)). 1 acts as the energy donor and NiR acts as the acceptor in 
      the FRET system with the optimum concentrations ratio [1]/[NiR] = 100. Besides, 
      the AIE(1) itself displays excellent selectivity for Cu(2+) ions at 525 nm with 
      the detection limit of 1.32 x 10(-7) M. While through the FRET system of 1-NiR 
      system, the detection limit of Cu(2+) can be further decreased to 9.12 nM by 
      monitoring the fluorescence at 630 nm. As a result, using an AIE probe to detect 
      Cu(2+) based on FRET mechanism is a promising strategy.
