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 .
