文摘
- •
[Ln(tfaa)3phen] complexes were synthesized with low hydrogen content (2.52–2.78%).
- •
Sparkle/RM1 structures were supported by FT-IR, ESI–MS and NMR.
- •
Visible luminescence of ternary complexes was studied in solution.
- •
Theoretical and experimental photophysical properties of Eu complex are in agreement.
- •
Ligand-to-metal energy transfer is dominated by the exchange mechanism.
