In addition, the researchers conducted a series of experimental and simulation studies on the mechanism of CEAA dye synthesis. The key to synthesizing CEAA dyes is the appropriate concentration difference between different dyes. Due to the principle of “like dissolves like”, the dyes that precipitate first encapsulate the dyes that have not yet precipitated, thus preventing further (self)-aggregation of the latter. The authors used the experimental methodology as a guide to achieving an efficient light-harvesting system and demonstrated the versatility of CEAA dye preparation.
This work discusses the synthetic approach for preparing CEAA dyes by antisolvent precipitation, which is enlightening for obtaining coemissive luminescent nanoparticles. In addition, the controlled cascade FRET process provides new ideas for developing novel luminescent materials for a very vast range of applications. Future work should focus on the stability of CEAA dyes, their application areas, and the exploitation of their synthetic approaches.
