Description

一种用于检测氟离子的探针化合物及其检测方法
技术领域
本发明属于阴离子荧光分析检测技术领域,尤其是涉及一种具有氟离子(F-)检测用途的荧光探针化合物N-3-羟基-4-2’-苯并噻唑苯-3,5-二苯甲氧苯甲酰胺,以及该化合物作为比率荧光探针检测氟离子的方法。
背景技术
阴离子广泛存在于生物体系中,在生物学、化学、医学和环境科学等领域扮演着重要的角色,因此,人们对阴离子的选择性识别和检测越来越感兴趣。在众多阴离子中,氟离子是电负性最强、离子半径最小的阴离子,广泛存在自然界之中,也是人体必需的微量元素之一,由于在龋齿预防、骨质疏松症治疗等领域的显著作用而受到特别关注。但是过量氟离子的摄入将引起氟中毒,对人体有极大的危害,导致氟斑牙,氟骨癌等疾病。因此,氟离子的识别与检测显得尤为重要。
传统的检测氟离子的方法主要有氟离子选择电极法、离子色谱法、19F NMR谱、氟试剂比色法和荧光探针法,其中,荧光探针法因具有选择性好、灵敏度高、方便快捷等特点而备受关注。目前已经报道的氟离子荧光探针多为荧光增强型探针[1-7],此类探针的量子效率易受环境影响,因此在实际应用中有一定的局限性,而比率型荧光探针可以避免检测环境的影响,实现对氟离子动态变化过程的定量检测,但是利用比率型荧光探针检测氟离子含量的报道较少[8,9],而且已报道的这类探针存在一些缺陷,如灵敏度低[8]、响应范围窄[9]等,所以发展测定氟离子的新的比率荧光探针十分重要。

发明内容
为弥补现有技术不足,本发明提供了一种具有F-检测用途的化合物N-3-羟基-4-2’-苯并噻唑苯-3,5-二苯甲氧苯甲酰胺(简称为a)。
本发明提供的探针化合物的结构为:
本发明的探针化合物检测F-浓度的方法:
将探针化合物溶于DMSO配成浓度为1×10-3mol/L的溶液A,取溶液A溶于含有乙腈的样品池中,混合均匀后得到探针化合物浓度为1×10-5mol/L的混合液B,向混合液B中逐渐滴加含F-的乙腈溶液,使得加入后F-的摩尔浓度依次是探针化合物的2,5,10,50,80,100,150,200,230倍,分别测定每次滴加含F-的乙腈溶液后激发波长为370nm的荧光光谱,以450nm与500nm荧光强度的比值(I450/I500)为纵坐标,F-浓度与探针化合物浓度比值([F-]/[a])为横坐标做工作曲线,趋势线方程为:
I450/I500=0.0012[F-]/[a]+0.0562(R2=0.9938)。
探针化合物对F-的工作浓度范围2×10-5~2×10-3mol/L,AcO-、H2PO4 -、HSO4 -和Cl-对F-浓度的测定无明显干扰。
进一步的,所述的含F-的乙腈溶液为四丁基氟化铵的乙腈溶液。
本发明的探针化合物对F-的选择性很高,能够选择性识别F-,适用于生物化学和环境化学等领域中F-的检测。本发明的探针化合物是F-检测的比率荧光识别探针,从而消除了荧光增强型探针等受外界不稳定带来的仪器的系统误差、背景误差等,使其灵敏度提高。
附图说明
图1是本发明实施例1中探针化合物的乙腈溶液在加入不同阴离子后的荧光吸收光谱图;
图2是本发明实施例2中探针化合物的乙腈溶液在加入0-230摩尔倍数的四丁基氟化铵后的荧光吸收光谱图;
图3是本发明实施例2中探针化合物在乙腈溶液中450nm与500nm荧光强度的比值(I450/I500)和F-摩尔浓度与探针化合物a摩尔浓度比值([F-]/[a])的工作曲线。
具体实施方式
下面通过具体实施例详述本发明,但不限制本发明的保护范围。如无特殊说明,本发明所采用的实验方法均为常规方法,所用实验器材、材料、试剂等均可从化学公司购买。
实施例1
将探针化合物N-3-羟基-4-2’-苯并噻唑苯-3,5-二苯甲氧苯甲酰胺溶于DMSO配成浓度为1×10-3mol/L的溶液A,取30μL溶液A溶于含有3mL乙腈的样品池中,将溶液混合均匀后得到探针化合物的浓度为1×10-5mol/L的混合液B。分别制备含有不同阴离子的乙腈溶液,即四丁基氟化铵乙腈溶液、四丁基磷酸二氢铵乙腈溶液、四丁基硫酸氢铵乙腈溶液、四丁基乙酸铵乙腈溶液和四丁基氯化铵的乙腈溶液,向混合液B中分别加入上述五种溶液,使得加入后四丁基氟化铵的浓度为探针化合物的200倍,其它四种四丁基铵盐的浓度为探针化合物的1000倍,分别测定各溶液在激发波长为370nm的荧光光谱(如图1)。从图1可以看出,探针化合物对AcO-的响应非常弱,H2PO4 -、HSO4 -和Cl-都不能引起探针化合物的荧光光谱的变化,而只有F-在500nm处荧光发射峰猝灭的同时,在450nm处出现了新峰,呈现出比率荧光的特征。以上结果说明探针化合物作为F-的荧光探针具有很好的选择性。
实施例2
将探针化合物N-3-羟基-4-2’-苯并噻唑苯-3,5-二苯甲氧苯甲酰胺溶于DMSO配成浓度为1×10-3mol/L的溶液A,取30μL溶液A溶于含有3mL乙腈的样品池中,将溶液混合均匀后得到探针化合物的浓度为1×10-5mol/L的混合液B,向混合液B中逐步滴加四丁基氟化铵的乙腈溶液,使得加入后四丁基氟化铵的浓度分别是探针化合物的2,5,10,50,80,100,150,200,230倍,分别测定每次滴加后激发波长为370nm的荧光光谱(如图2)。随着氟离子浓度的增加,荧光光谱上500nm处荧光峰强度逐渐减弱,而在450nm处出现了一个新峰,且荧光峰强度逐渐增强,以450nm与500nm荧光强度的比值(I450/I500)为纵坐标,F-浓度与探针化合物浓度比值([F-]/[a])为横坐标做工作曲线,如图3所示,趋势线方程为:I450/I500=0.0012[F-]/[a]+0.0562(R2=0.9938)。
以上所述,仅为本发明创造较佳的具体实施方式,但本发明创造的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明创造披露的技术范围内,根据本发明创造的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明创造的保护范围之内。
