合成了Eu(Ⅲ)与α-噻酚甲酰三氟丙酮(HTTA)、三苯基氧化膦(TPPO)和苯甲酸(BA)及其衍生物对甲基苯甲酸(PTA)或对甲氧基苯甲酸(POA)形成的系列配合物.对所合成配合物利用元素分析、红外光谱、扫描电镜与荧光光谱等手段进行了表征.元素分析表明其组成为Eu(BA)(TTA)2TPPO2,Eu(PTA)(TTA)2TPPO2与Eu(POA)(TTA)2TPPO2.测定了配合物Eu(POA)(TTA)2TPPO2在甲醇中的紫外吸收与荧光激发光谱.结果表明,苯甲酸及其衍生物作第二配体加入到Eu3+的配合物中,能得到成本较低的系列鲜艳红色荧光材料,它们的相对荧光强弱顺序是:Eu(POA)(TTA)2TPPO2>Eu(PTA)(TTA)2TPPO2>Eu(BA)(TTA)2TPPO2.
