Problems solved by technology

[0003] According to literature reports, in recent years, people have paid more attention to the influence of substitution at different positions of the BODIPY matrix and the molecular space structure of derivatives on its photoelectric properties. This is due to the problems of self-polymerization and acid-catalyzed decomposition of the pyrrole ring. When some functional groups are introduced, the control of reaction conditions and the simplification of the post-treatment process are very critical.
