以邻、间、对甲氧基苯甲酸(o MOBA,m MOBA,p MOBA)为第一配体,以1,10邻菲啰啉(phen)为第二配体,合成了三种甲氧基苯甲酸铽(Ⅲ)与1,10邻菲啰啉的三元配合物ü胤治觥⑴湮坏味ǚ治?确定了配合物的组成分别为Tb(o MOBA)3phen·H2O、Tb(m MOBA)3phen·H2O和Tb(p MOBA)3phen。通过红外光谱对配合物的结构进行了表征,结果表明在配合物中羧基氧原子和邻菲啰啉中的氮原子均参与了配位ü夤馄追治?探讨了第一配体取代基位置的变化,对三元配合物的发光性能的影响。结果表明,三种配合物均具有优良的光致发光性能,各配合物的相应跃迁发射峰位基本上没有变化,5D4→7F6、5D4→7F5两个较强发射峰的强度顺序为:Tb(o MOBA)3phenoH2O>Tb(m MOBA)3phenoH2O>Tb(p MOBA)3phen。
Methylene oxide (o MOBA, m MOBA, p MOBA) as the first ligand and phenanthroline 1,10,10 as the second ligand were used to synthesize three kinds of methoxy Ternary complex of terbium (Ⅲ) benzoate and 1,10-phenanthroline ü 胤 治 觥 ⑴ annihilation taste ǚ governance? The composition of the complexes were determined Tb (o MOBA) 3phen · H2O , Tb (m MOBA) 3phen · H2O and Tb (p MOBA) 3phen. The structure of the complex was characterized by FTIR. The results showed that both the carboxyl oxygen atom and the nitrogen atom in ortho-phenanthroline were involved in the complexation. The first ligand The effect of substituent position on the luminescent properties of ternary complexes. The results show that the three complexes have excellent photoluminescence properties, and the corresponding transition emission peak positions of the complexes are basically unchanged. The intensity order of the two strong emission peaks of 5D4 → 7F6 and 5D4 → 7F5 is Tb o MOBA) 3phenoH2O> Tb (m MOBA) 3phenoH2O> Tb (p MOBA) 3phen.
