3. Conclusion
In summary, the intensive luminol-Co2+-H2O2system with long-lasting CL emission has been explored by introducing the C8-TPE-C4TAB AIE surfactant. The micelle-improved enrichment and diffusion control of reactants and CRET were critical to amplify the CL signals. The visible CL emissions can be observed even after 60 min reaction at pH 7.4. This work not only develops a simple and glow-type luminol CL system, but also provides a general tactic to construct the novel surfactant-mediated CL system by introducing AIE surfactant with ultralow CMC, which reduces the usage of surfactant and environmental pollution. Moreover, our work also provides a deep learning of the relationship between CMC and surfactant-improved CL signals. Therefore, we believe this strategy might benefit the exploration of green and effective CL systems for lighting, optical sensing and photocatalysis applications, etc .
