三功能合一的含铽高聚物的光谱性质研究

制备了一种新型的可平衡电荷(空穴与电子)传输的含铽高聚物。用红外光谱、飞行时间二次离子质谱、紫外光谱研究了其光谱性质，确认这种高聚物含有咔唑、铽络合物、噁二唑单元。用荧光光谱研究了不同状态下高聚物的荧光性质，来自共轭基团的荧光出现“荧光猝灭”。在紫外光照射下，高聚物可发出具有铽离子特征发射的纯绿光。

Study on Spectral Properties of Tri-Functional Polymers Containing Terbium Complex

In the present paper, a kind of tri-functional polymer containing terbium complex was synthesized. The spectral properties were studied by means of FTIR, UV-Vis, and TOF-SIMS. The results indicated that the polymer contained the oxadiazole group, carbazole group and terbium complex. The fluorescence property was investigated in different states. In solution, the spectra consisted of the emission band from the pi-->pi* transition of the oxadiazole and carbazole group and the emission peaks from the transitions between the 4f states of terbium. In solid state, the emission from the oxadiazole and carbazole group was suddenly suppressed, and the result also indicated that the efficiency of energy transfer in the solid state is much higher than that in solution. The polymer emits pure green light under the UV light in solid state.
