Abstract: In this paper,four new amphiphilic N-hexadecyl pyridinium tetrakis(3-phenyl-4-benzoyl-5-isoxazolone) lanthanide complexes, Ln(PBI)4·HDP(Ln=Sm,Eu,Tb,Dy),were synthesized and characterized by elementary analysis,FT-IRspectra,TG-DTAanalysis and UV-Vis spectra, Their luminescent properties were studied and showed that they have good fluorescence 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 results show that all of them could form stable Langmuir films,This provides valuable data for the application of fluorescent lanthanide complexes in the microcavity laser oscillations.
