摘要
通过在邻菲啉中性配体上引入萘酰亚胺发色团,合成了新型含有萘酰亚胺单元的铕配合物Eu(DBM)3(PNI-phen).通过控制激发,可以得到具有萘酰亚胺和Eu3+特征发射的荧光光谱.通过荧光光谱和激发光谱研究了铕配合物的能量传递及发光机制.
A novel complex Eu(DBM)3 (PNI-phen) was synthesized via incorporation of naphthalimide unit to the neutral ligand of 1,10-phenanthroline, which enables the europium complex to exhibiting the characteristic luminescence of naphthalimide unit and Eu^3 + ion via selective excitation. The pathway of energy transfer and the luminescence mechanism were studied by the fluorescence and excitation spectra.
