摘　　要：根据文献方法合成大环配体L,通过溶剂法与金属盐Fe(ClO4)2·6H2O反应合成了两个新的菲罗琳大环双核Fe^3+配合物[Fe2(L)(μ-O)(DMF)4]·4ClO4(1,CCDC:1834054)和[Fe2(L)(μ-O)(SCN)4]·4ClO4(2,CCDC:1834055),其结构经IR和元素分析表征。晶体结构解析表明:1属三斜晶系,2属单斜晶系。配合物中两个铁原子通过一个氧桥进行连接,由于氧桥的连接使得配体发生折叠进而产生了π-π堆积。配体荧光滴定实验显示,配体L对过渡金属存在响应,随着过渡金属离子的加入,配体的荧光强度不断减弱。The ligand L was synthesized according to the literature. Two complexes,[Fe 2 (L)(μ-O)(DMF) 4 ]·4ClO 4 ( 1 , CCDC:1834054)and [Fe 2 ( L )(μ-O)(SCN) 4 ]·4ClO 4 ( 2 , CCDC:1834055), were synthesized by solvent reaction of L with Fe(ClO 4 ) 2 ·6H 2 O. The structures were characterized by IR and elemental analysis. Crystal structure analysis showed that 1 belongs to triclinic crystal system and 2 belongs to monoclinic crystal system. Due to the formation of a Fe(1)-O-Fe(2) oxygen bridge, folding occurred and intramolecular π-π stacking was formed in the phenanthroline moiety. The ligand fluorescence titration experiment showed that L was responsive to transition metal, with the addition of transition metal ions, the fluorescence intensity of L was continuously weakened.
