Combining tetraphenylethene (TPE) derivative cations with Eu3+-β-diketone complex anions for tunable luminescence

Tetraphenylethene (TPE) derivative cations (TPE+) and Eu3+-beta-diketone complex anions (Eu(ABM)(4)(-)) were combined to construct a novel dual energy transfer system (TPE+ to Eu3+ and ABM to Eu3+). Our system exhibits tunable luminescence in DMF/water mixtures under different f(w) conditions owing to the AIE and ACQ properties of TPE+ and ABM, respectively. Its luminescence can be also regulated by adding P-containing oxysalts or polyacrylic acids.

Automated summary

TPE+ and Eu(ABM)(4)(-) are combined to create a dual energy transfer system with tunable luminescence. The luminescence can be regulated by adding P-containing oxysalts or polyacrylic acids.
