Controlling aggregation-induced emission of iridium(Ⅲ) complexes via molecular hydrophilic-lipophilic interactions and in-situ electrostatic self-assembly.

Exploring the internal relationship between the structure and properties of AIE-active iridium complexes and their applications have been great significance. It is imperative to acknowledge that the precise control of nanoparticle morphology and particle size of organic molecules in solutions remains elusive, while comprehending the luminescent mechanisms of self-assembled aggregates continues to present a challenge. The previously work proposed that solvent-induced amphiphilic molecules could enhance the self-assembly properties of iridium complexes, but the influence of ligands' hydrophilic-lipophilic interactions on the AIE characteristics of iridium complexes remained unclear.
