以间氨基苯酚与三氟乙酰乙酸乙酯反应生成4-三氟甲基-7-氨基香豆素,其与氯乙酰氯反应生成4-三氟甲基-7-氯乙酰氨基香豆素.该化合物与透明质酸钠反应得到了含氟香豆素透明质酸衍生物.利用荧光光谱等分析技术研究了浓度、pH值和温度变化对该透明质酸衍生物荧光强度的影响,同时研究了金属离子对其荧光强度的影响.结果表明,一定浓度范围内,荧光强度随透明质酸衍生物浓度增大而逐渐增强;在pH值为3.86 ～8.85范围内,其荧光强度较为稳定;在10～80℃范围内,其荧光强度随温度的升高而逐渐减弱;在常见于扰离子存在下,Fe3+对其荧光强度有较为显著的影响,其荧光强度显著降低.这为探索透明质酸在生命机体内的药物载体机理及其靶向作用提供良好的实验基础.
