苯甲酸及其衍生物和噻吩甲酰三氟丙酮铕配合物的合成与荧光性质

Synthesis and Fluorescent Properties of the Complexes of Benzoic Acid or Its Derivatives with α-thenoyltrifluoroacetone Europium(Ⅲ)

合成了苯甲酸(BA)及其衍生物对甲基苯甲酸(PTA)、对甲氧基苯甲酸(POA)与α-噻吩甲酰三氟丙酮(HTTA)和三苯基氧化膦(TPPO)形成的3个Eu(Ⅲ)-配合物.分析了它们的组成与结构,常温下研究了它们的荧光光谱.发现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,其中对甲氧基苯甲酸比苯甲酸、对甲基苯甲酸具有更好的荧光敏化效果.

Three europium （Ⅲ） complexes of α-thenoyltrifluoroacetone （HTTA） with benzoic acid （BA） or its two derivatives, p-toluic acid （PTA） and p-methoxybenzoic acid （POA）, and trioctylphosphine oxide （TPPO） were synthesized, and their composition and structure was investigated. The fluorescence spectra of the solid phos-phor were studied at ambient temperature. The experimental result showed that the fluorescence of Eu （Ⅲ）-HTTA- POA-TPPO is stronger than that of Eu （Ⅲ） -HTTA-BA （PTA）-TPPO. Relative cheap sharp red luminescent materials have been prepared.
