摘　　要：利用萘羟基醛与苯胺衍生物为原料获取中性Schiff配体HL(1-[N-(4-X苯基)]氨甲基-2(1 H)萘酮,X=-Br,HL-Br;-I,HL-I),采用挥发法和液相扩散法分别合成了单核稀土配合物[Tb(HL-Br)_(2)(NO_(3))_(3)CH_(3)OH](1Tb,CCDC:2162196)和[Tb(HL-I)_(3)(NO_(3))_(3)](2Tb,CCDC:2164830),并利用X-射线单晶衍射、元素分析、红外光谱(FT-IR)、粉末-X射线衍射(PXRD)及热重分析(TG)对其结构和热稳定性进行了表征。固体荧光测试发现,相较于单个配体分子,2例配合物的荧光强度大幅增加,有望发展成为新型荧光材料。Mononuclear rare earth complexes[Tb(HL-Br)_(2)(NO_(3))_(3)CH_(3)OH](1Tb,CCDC:2162196)and[Tb(HL-I)_(3)(NO_(3))_(3)](2Tb,CCDC:2164830)were synthesized by neutral Schiff-Base HL,(1-[N-(4-X phenyl)]aminomethyl-2(1 H)naphthalene,X=-Br,HL-Br;-I,HL-I)based on naphthalene hydroxyl aldehydes and aniline derivatives.The corresponding complexes were characterized by X-ray single crystal diffraction,elemental analysis,FT-IR and powder-X-ray diffraction(PXRD)and thermogravimetric analysis(TG).Solid-state fluorescence spectra indicated that the fluorescence intensity of the two complexes increased significantly compared with free HL ligangs,which was expected to be developed into new fluorescent materials.
