SYNTHESIS, LUMINESCENT PROPERTIES AND LAN GMUIR FILMS OF 4 NEW AMPHIPHILIC N-HEXADECYL PYRIDINIUM TETRAKIS(3-PHENYL-4-BENZOYL-5-ISOXAZOLONE) LANTHANIDE COMPLEXES

In this paper, four new amphiphilic N-hexadecyl pyridinium tetrakis (3 -phenyl-4-benzoyl-5-isoxazolone) lanthanide complexes, Ln(PBI)(4) . HD P (Ln = Sm, Eu, Tb, Dy), were synthesized and characterized by element ary analysis, FT-IR spectra, TG-DTA analysis and UV-Vis spectra. Their luminescent properties were studied and showed that they have good fl uorescence performances. Their fluorescent lifetime was determined by using the frequency-domain method. Besides, the Langmuir films of the four complexes on the air/water interface were also studied, the resul ts show that all of them could form stable Langmuir films. This provid es valuable data for the application of fluorescent lanthanide complex es in the microcavity laser oscillations.
