| 摘要: 在水热条件下2个配体特戊酸(pivH)和1-H-咪唑[4，5-f][1，10]-菲咯啉(IP)和稀土金属反应得到了6个稀土配合物[Ln(piv)3(IP)2]，(Ln=Nd(1)，Eu(2)，Gd(3)，Tb(4)，Dy(5)，Ho(6))。结果显示，2个混合配体和不同的稀土金属形成了6个相似的零维结构，进而通过N-H…O氢键和π-π堆积作用，形成一维链状结构。6个配合物均用元素分析、粉末衍射(PXRD)、红外光谱(FTIR)进行了表征，且对配合物2和4的荧光性质及1和2的热稳定性进行了详细的分析。 | |

| Abstract: A series of novel monometallic coordination complexes[Ln(piv)3(IP)2], (Ln=Nd (1), Eu(2), Gd(3), Tb (4), Dy(5), Ho(6), IP=1-H-imidazo[4,5-f] [1,10]-phenanthroline, pivH=pivalic acid) have been successfully synthesized under hydrothermal condition. Complexes 1~6 have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectroscopy and powder X-ray diffraction. The result reveals that all the six new complexes present similar 0-dimensional structures, which are further extended into the one-dimensional (1D) architectures through hydrogen bonds and π-π stacking interactions. Meanwhile, the thermogravimetric analyses of complexes 1 and 2 and photoluminescent properties of complexes 2 and 4 have also been investigated. | |
