以对苯二甲酸(p-PA)、苯甲酸(BA)、邻(间、对)甲基苯甲酸和1
10-邻菲啰啉(phen)为配体
合成了4种Eu(Ⅲ)和4种Tb(Ⅲ)的四元配合物。通过EDTA配位滴定分析和元素分析
确定了各配合物的组成。利用红外光谱分析对配合物的结构进行了初步表征
在配合物中羧基氧原子和1
10-邻菲啰啉中的氮原子均参与了配位。在室温条件下
测定了各固体配合物的激发和发射光谱
结果表明:4种铕的四元配合物中
苯甲酸配合物在614nm最强发射峰的荧光强度强于3种甲基取代苯甲酸配合物的荧光强度;4种铽的四元配合物中
以对甲基苯甲酸为配体的配合物在545nm最佳发射峰和490nm次强发射峰的荧光强度较高。
