Crystal Structure and Luminescence of [Eu(TTA)3·DAF]·0.5C7H8 Complex Excited by Visible Light

Abstract The non‐ionic europium(III) complex [Eu(TTA) 3 ·DAF]·0.5C 7 H 8 (TTA = 2‐thenoytrifluoroacetonate, DAF = 4, 5‐diazafluoren‐9‐one) was synthesized. The structural determination has been carried out. DAF coordination induces the both excitation spectra in the solid state and solution having a red shift and sensitizes Eu 3+ luminescence under visible light excitation.
