摘要: 以2, 2′:6′, 2″-三联吡啶(L1)为基础, 通过引入不同的空穴传输基团合成了4′-咔唑基-2, 2′:6′, 2″-三联吡啶(L2), 4′-二苯基胺基-2, 2′:6′, 2″-三联吡啶(L3), 4′-二(4-叔丁基苯基)胺基-2, 2′:6′, 2″-三联吡啶(L4), 4′-(N-苯基-1-萘基)胺基-2, 2′:6′, 2″-三联吡啶(L5), 4′-(N-苯基-2-萘基)胺基-2, 2′:6′, 2″-三联吡啶(L6)5个N, N, N-三齿中性配体, 然后以三氟乙酰噻吩丙酮(HTTA)作为第一配体合成了6种铕配合物。在369~373 nm激发条件下, 配合物都表现出铕离子⁵D₀-⁷F_J(J=0, 1, 2, 3, 4)的特征发射。引入不同的空穴传输基团后, 在铕离子的周围形成了“光吸收天线”(light-harvesting antenna), 不仅扩大了配合物吸收光能的范围、增强了配合物的吸收强度, 而且提高了配合物的光致发光性能。其中含有咔唑基团的配合物具有最强的发光强度和最长的激发态寿命。

Abstract: Based on 2, 2′:6′, 2″-terpyridine (L1), five N,N,N-tridentate ligands, namely 4′-carbazol-9-yl-2,2′:6′,2″-terpyridine (L2), 4′-diphenylamino-2,2′:6′,2″-terpyridine (L3), 4′-bis(4-tert-butylphenyl)-amino-2,2′:6′,2″-terpyridine (L4), 4′-(1-naphthalenyl-N-phenyl)amino-2,2′:6′,2″-terpyridine (L5), 4′-(2-naphthalenyl-N-phenyl)amino-2,2′:6′,2″-terpyridine (L6), have been successfully synthesized. Employing 2-thenoyltrifluoroacetone (HTTA) and L1-L6 as the sensitizing ligands, a series of europium (Ⅲ) complexes (Eu(TTA)₃L1-Eu(TTA)₃L6) have been obtained. All the europium (Ⅲ) complexes show red characteristic emission of Eu(Ⅲ) ⁵D₀-⁷F_J(J=0,1,2,3,4). The introduction of hole transport moieties improves the UV-Vis absorption and luminescence intensities of the europium(Ⅲ) complexes, and the carbazole containing complex Eu(TTA)₃L₂ exhibits the highest intensity and longest lifetime.

Key words:

europium complex;hole transport moiety;luminescence, lifetime
