Synthesis and Optical Properties of Dysprosium Nano Fluorescent Materials

利用DFT/B3LYP/6-31G的方法对槲皮素结构参数、分子轨道能量的数据及羟基氢原子电荷分布分析,结果表明C4位酚羟基具有较强抗氧化活性,证明此位点的羟基氢参与自由基清除得可能性最大,从量子计算的角度阐释了槲皮素具有抗氧化的药理活性的量子原理。采用常规方法合成纳米镝稀土配合物,通过测量其红外光谱、紫外光谱、荧光光谱特征以及电化学分析和量子计算来研究它。研究表明,镝稀土元素可以与槲皮素生成化学性质稳定的配合物且具有生物活性,可广泛应用于疾病患者的治疗与诊断。

Using DFT/B3LYP/6-31G method for quercetin structure parameters,data and hydroxyl hydrogen molecular orbital energy,charge distribution,the result showed that C4 a phenolic hydroxyl group has strong antioxidant activity,proved that the site of hydroxyl hydrogen radical scavenging to participate,most likely from the quantum computing the pharmacological activities of quercetin with antioxidant of quantum theory.Nanometer dysprosium rare earth complexes were synthesized by conventional methods,and their properties were studied by measuring their ir,uv and fluorescence spectra,electrochemical analysis and quantum computation.Studies have shown that dysprosium rare earth element can form a chemically stable complex with quercetin and has biological activity,which can be used in the treatment and diagnosis of disease patients.
