通过将PDDA(=聚N-十二烷基丙烯酰胺)和Eu(TTA)3Phen(=4，4，4-三氟-1-(2-噻吩基)-1，3-丁二酮)-1，10-菲咯啉Eu(III)的混合溶液分散到饱和的水亚相中，制备了含Eu配合物的聚合物LB膜。从表面压力-面积等温线可以看出，p(DDA/Eu(TTA)3Phen)为凝聚型单层结构。该单分子膜可以Y型LB膜的形式转移到固体载体上。通过荧光光谱和时间分辨发光衰减测量，研究了Eu(TTA)3Phen在聚合物LB膜中的光谱性质。
Polymer LB films containing europium complexes (p (DDA/Eu (TTA) 3 Phen)) were prepared by spreading a mixed solution of pDDA (= poly (N-dodecylacrylamide)) and Eu (TTA) 3 Phen (= 4, 4, 4-trifluoro-1-(2-thienyl)-1, 3-butanediono)-1, 10-phenanthroline europium (III)) onto a water subphase in which the complexes and their ligand groups were saturated. From the surface pressure-area isotherms, it was found that p (DDA/Eu (TTA) 3 Phen) takes a condensed monolayer formation. The monolayer could be transferred on solid substrates as Y-type LB films. The spectroscopic properties of Eu (TTA) 3 Phen in the polymer LB films were investigated by fluorescence spectroscopy and time-resolved luminescence decay measurement.
