Abstract
Relationships between molecular structures of aromatic- and aliphatic-substituted diphosphine dioxide ligands and properties of Eu(III) complexes were investigated. Substitution of CF3 groups in phenyl groups of diphosphine dioxide ligands has an outstanding effect in terms of both reducing the sum of the enthalpy of fusion and phase transition (ΔHsum) and enlarging solubility. Large photoluminescence intensity and solubility were realized when the number of methylene units between two PO groups of diphosphine dioxide ligands (n) was 3. Eu(III) complex 6 with the diphosphine dioxide ligand that satisfies both conditions (substitution of CF3 groups and n = 3) is highly soluble in a fluorinated solvent and has relatively large photoluminescence intensity. It is a promising candidate for LED devices, security media and sensing applications.
