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.
