A hexaphenylbenzene based AIEE active probe for the preparation of ferromagnetic α-Fe2O3 nanoparticles: facile synthesis and catalytic applications.

Fluorescent aggregates formed by self-assembly of a hexaphenylbenzene based derivative serve as a reactor and a stabilizer for the formation of ferromagnetic iron oxide (α-Fe2O3) nanoparticles in aqueous medium at room temperature. These α-Fe2O3 nanoparticles showed excellent catalytic activity in palladium, copper and amine free Sonogashira cross coupling reactions and also in photocatalytic degradation of rhodamine B dye.
