synthesis,Luminescent Properties and Langmuir Films of Four New Amphiphilic N-Hexadecyl Pyridinium Tetrakis(3-phenyl-4-benzoyl-5-isoxazolone)Lanthanide Complexes

合成了４种两亲性的３－苯基－４－苯甲酰基－５－异唑酮（ＨＰＢＩ）合稀土酸十六烷基吡啶配合物：Ｌｎ（ＰＢＩ）４·ＨＤＰ（Ｌｎ＝Ｓｍ，Ｅｕ，Ｔｂ，Ｄｙ）．用元素分析、红外光谱、差热－热重谱、紫外－可见光谱对其进行了表征。研究了这４种配合物在固态下的荧光光谱并用频域法（Ｆｒｅｑｕｅｎｃｙ－ｄｏｍａｉｎ）测定了它们的荧光寿命，另外，还对这４种配合物在空气／水界面上单分子膜的（Ｌａｎｇｍｕｉｒ膜）行为进行了研究，表明它们均能形成稳定的单分子膜。

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-IR spectra,TG-DTA analysis 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.
