| 摘要: 线性共轭高分子P-1是由单体1，4-二溴-2，3-二正丁氧基萘(M-2)和5，5′-二乙烯-2，2′-联吡啶(M-3)通过Pd催化Heck偶合反应合成得到，高分子配合物P-2和P-3由高分子P-1和Eu(TTA)3·2H2O和Gd(TTA)3·2H2O反应生成。高分子P-1能发射强蓝绿色荧光。高分子配合物P-2和P-3发光性能测试表明，含有Eu(Ⅲ)的高分子配合物P-2不仅显示高分子荧光，而且还显示了Eu(Ⅲ)(5D0 → 7F2)特征荧光，含Gd(Ⅲ)的高分子配合物P-3仅发射高分子的荧光，其荧光波长相对P-1而言，呈现13 nm红移。 |

| Abstract: Linear conjugated polymer P-1 showing strong blue-green fluorescence was synthesized by the polymerization of 1,4-dibromo-2,3-bisbutoxynaphthalene (M-2) with 5,5′-divinyl-2,2′-bipyridine (M-3) via Heck reaction. The polymer complexes P-2 and P-3 were obtained by the bipyridyl coordination of P-1 with Eu(TTA)3·2H2O and Gd(TTA)3·2H2O (TTA=2-thenoyltrifluoroacetonate). Based on the fluorescent property of the polymer and RE(Ⅲ)-containing polymer complex, Eu(Ⅲ)-containing polymer complex P-2 can not only emit the polymer fluorescence, but also has the characteristic fluorescence of Eu(Ⅲ) (5D0 → 7F2) under different excited wavelengths. Gd(Ⅲ)-containing polymer complex P-3 only emits the polymer fluorescence, but fluorescence wavelength has a redshift of about 13 nm with respect to P-1. |
