通过先聚合再配合的方法成功制备了两种羧酸类大分子稀土铕配合物PAA-Eu和ST-AA-Eu,并将其与合成的小分子稀土配合物Eu(AA)3形成对比.经红外光谱初步表征发现稀土配合物已经配位成功且其配位数为6.分另j采用凝胶渗透色谱(GPC)和等离子发射光谱(ICP)分析大分子稀土配合物的分子量与稀土铕的含量.由TG分析配合物的分解温度并了解其热稳定性能和组分,采用荧光激发发射光谱研究其荧光性能,采用SEM分析配合物与基质的相容性.结果表明,大分子稀土配合物的热稳定性稍差于小分子稀土配合物,其中ST-AA-Eu由于苯环的介入热稳定性能稍好.小分子稀土配合物Eu(AA)3的荧光强度明显要比大分子稀土配合物强,大分子稀土配合物PAA-Eu的荧光强度比ST-AA-Eu强,配合物都发红光;大分子稀土配合物与基质的相容性比小分子稀土配合物好.
