Abstract

The rare-earth carboxylate complexes are a kind of good luminous materials.With the tremendous progress of OEL

the research of rare-earth carboxylate complexes as electroluminescent device emitting layer material is increasing.The application prospects of these complexes become more and more broad.Tb (Ⅲ) earboxylate complexes are a kind of good green luminescence material.In our previous work

we found that some neutral conjugated heterocyclic ligands (such as phen or bipy) can enhance the luminescent intensity to some extent in Tb (Ⅲ) aromatic carboxylate compounds.In these studies about rare-earth aromatic carboxylate complexes

a lot of researches about the complexes of terbium with carboxylate have been reported

but the study of terbium complexes with halogen-benzoic acids as the first ligand is seldom reported.In order to compare the properties of the complexes in series

nine ternary complexes of rare-earth halogen-benzoic acids with 1

10-phenanthroline were synthesized in this paper.These complexes were characterized by elemental analysis

IR and TG-DTG methods.In these complexes

the Tb (Ⅲ) ions are bonded to the oxygen atoms of carboxylate and the nitrogen atoms of phen.The TG-DTG analysis showed that these complexes are thermally stable.The stability order of the complexes is:Tb (o-CIBA)

O.Their excitation and luminescence spectra were performed under identical conditions and instrumental parameters at room temperature.The results indicate that the fluores-cence intensity changes with the different substituent on the benzene ring or the same substituent in different positions.The order of their fluorescence intensity is Th (o-FBA)
