Abstract

In this paper

imidazo phenanthroline(IP) and 2-diphenylamine carbonyl benzoic (HDPAB) were synthesized. Then HDPAB was used as the first ligand and IP as the secondary ligand

a new ternary organic terbium complex Tb(DPAB)

IP was prepared. In the same condition

with the same first ligand

Tb(DPAB)

phen was prepared where phen as the second ligand. The structures and compositions of the ligands and ternary complexes were confirmed by elemental analysis

IR spectra and UV spectra

the fluorescence properties of the two terbium complexes were also studied. Elemental analysis demonstrated that the compositions of the ternary complexes were Tb(DPAB)

IP and Tb(DPAB)

phen. IR spectra indicated that rare earth Tb

ion coordinated with six oxygen atoms of three benzoic acid ligands and two nitrogen atoms of the second ligand. UV spectra showed that the main absorption was from HDPAB in the ternary complex.Fluorescence spectra demonstrated that two kinds of ternary organic terbium complexes could emit characteristic fluorescence of rare earth Tb

and the second ligand IP had stronger conjugation system. With the excitation of ultraviolet

the energy absorbed by the ligands in the complexes could be transfered to the rare earth Tb

ion

so they could emit characteristic fluorescence and the fluorescence intensity of Tb(DPAB)

IP was obviously higher than that of Tb(DPAB)

phen. Thus the appropriate secondary ligand of imidazo Phenanthroline (IP) obviously enhanced the fluorescent intensity of terbium complex. So

the new ternary organic terbium complex of Tb(DPAB)

IP is an excellent green-emitting material.
