AB  - Improving mechanochemiluminescent (MCL) sensitivity of 1,2-dioxetane containing 
      polymers is important for the applications of stress-reporting soft materials. 
      Herein, a series of MCL poly(dimethylsiloxane) (PDMS) have been synthesized by 
      simultaneously incorporating difluoroboron beta-diketonate dye and 1,2-dioxetane as 
      the co-crosslinkers to tune the energy transfer process across polymer chains. By 
      covalently linked fluoroboron complex in PDMS network, the aggregation of the 
      complex is overcome. Owing to its excellent opto-physical properties, this 
      fluoroboron complex is shown to be an effective in-chain fluorophore to 
      effectively enhance the chemiluminescence from polymeric 1,2-dioxetane that is 
      broken either thermally or mechanically. Studies on the optomechanical properties 
      of these PDMS show that MCL intensity is increased with the concentration of 
      fluoroboron complex and the wavelength of the emission is shifted. The results of 
      the present study appear to be broadly useful for designing elastomeric networks 
      with chemiluminescent property not only attractive for optical technology, but 
      also useful for damage self-reporting.
