Aggregation-Induced Emission of Curcuminoid-BF 2 Complex for Phosphor-Converted Red Light-Emitting Diode.

The incorporation of difluoroboron β-diketonate and tetraphenylethene under a facile Knoevenagel condensation reaction afforded one new D-π-A-π-D complex TCBF with high aggregation-induced emission (AIE) activity. The TCBF film can maintain a high photocurrent after long-term (500 min) photoelectronic measurements. The successful fabrication of a red LED device makes it a promising candidate for high-performance solid-state lighting.
