a fluorine functionalized 1,10-phenanthroline ligand, 3-ethyl-2-(2-fluorophenyl) imidazo[4,5-f]1,10-phenanthroline(EFPIP) and the corresponding red-emitting Eu(ΙΙΙ) complex Eu(DBM)3(EFPIP) (DBM = dibenzoylmethanate) was synthesized and the photophysical properties and electroluminescent(EL) performances were researched. When Eu(DBM)3(EFPIP) was used as emitting material in organic devices, the maximum efficiency and luminance of red emission achieved from the EL device with the configuration of ITO/m-MTDATA (30 nm)/NPB (20 nm)/ x wt% Eu(DBM)3(EFPIP) doped in CBP (30 nm)/Bphen (20 nm)/Alq3 (20 nm)/LiF (0.8 nm)/Al were 3.6 cd/A and 563 cd/m2, respectively. Compared with the previously reported devices based on methyl or chlorine substitute Eu(ΙΙΙ) complexes, the EL performances of the device using Eu(DBM)3(EFPIP) as an emitter was significantly enhanced due to the introduction of fluorine.

We have designed and synthesized novel luminescent lanthanide complexes based on a naphthalene derivative. The coordination number of complexed ligands with Eu 3+ ions is an important parameter to enhance the photoluminescence (PL) intensity. The photoluminescence spectra of Eu ( III )-cored complexes exhibit a sharp red emission band at 612 nm, corresponding to the 5 D 0→7 F 2 transition of the trivalent Eu ion. The saturated europium complexes (C-2 and C-3) have much stronger PL intensity than the unsaturated 6-coordinated europium complex (C-1), due to the instability of the C-1 complex. In this paper, the synthesis and photophysical properties of novel europium(III)-chelated complexes based on a naphthalene derivative will be discussed.
