In 2022,Biesen, Lukas; Krenzer, Julius; Nirmalananthan-Budau, Nithiya; Resch-Genger, Ute; Mueller, Thomas J. J. published an article in Chemical Science. The title of the article was 《Asymmetrically bridged aroyl-S,N-ketene acetal-based multichromophores with aggregation-induced tunable emission》.Safety of Tris(4-bromophenyl)amine The author mentioned the following in the article:
Asym. bridged aroyl-S,N-ketene acetals and aroyl-S,N-ketene acetal multichromophores can be readily synthesized in consecutive three-, four-, or five-component syntheses in good to excellent yields by several successive Suzuki-couplings of aroyl-S,N-ketene acetals and bis(boronic)acid esters. Different aroyl-S,N-ketene acetals as well as linker mols. yield a library of 23 multichromophores with substitution and linker pattern-tunable emission properties. This allows control of different communication pathways between the chromophores and of aggregation-induced emission (AIE) and energy transfer (ET) properties, providing elaborate aggregation-based fluorescence switches. In the experiment, the researchers used many compounds, for example, Tris(4-bromophenyl)amine(cas: 4316-58-9Safety of Tris(4-bromophenyl)amine)
In other references, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)Safety of Tris(4-bromophenyl)amine
