双亲性邻苯二甲酸正十八醇单酯稀土配合物的合成、发光、能量传递及成膜性能

Synthesis, Luminescence, Energy Transfer and Langmuir Blodgett Films of Amphiphilic Complexes of Rare Earths with Monooctadecyl Phthalate

自从ＶｏｎＨａｎｓＫｕｈｎ［１］首次发表了关于稀土配合物ＬＢ膜的研究以来，随着材料科学的不断发展，功能稀土配合物ＬＢ膜以其在导电［２，３］、非线性光学［４，５］、磁学［６，７］和光学［８，９］等领域中的优异性能愈来愈引起人们的注意，并取得了可喜的进展...

Three new amphiphilic rare earth complexes with only two organic long chains Ln(MOP) 2Cl (MOP=monooctadecyl phthalate, Ln=Eu, Tb, Gd) were synthesized and characterized by elemental analysis. The complexes (Eu, Tb) showed good luminescence property with long fluorescence lifetime, whereas the intensity and lifetime of Tb complex are greater than those of Eu complex. By measuring the triplet energy levels of ligand based on energy transfer mechanism, above phenomena have been well explained. The Langmuir films of the complexes on the air/water interface were also studied and the results show that all of them have good film forming property.
