Description

一种检测零价钯的有机小分子探针及其制备方法
技术领域
本发明属于重金属检测技术领域,具体涉及一种检测零价钯的有机小分子探针及其制备方法。
背景技术
钯是一种重要的过渡金属元素,可用作汽车催化剂、珠宝首饰和石油催化剂等。但在广泛应用的同时,也造成了钯残留和钯污染,残留的钯有可能通过食物链富集到人的体内,钯作为一种亲硫元素,进入人体后有可能和含有硫元素的氨基酸、蛋白质或其他生物大分子结合,进而影响人的身体健康,如偏头疼、面部麻痹等。目前已有许多国家对重金属钯进行严格限制,比如:每人每天饮食摄入的钯不得超过1.5-15μg。因此,研究对重金属钯具有高灵敏度和高选择性的检测方法具有非常重要的实际意义。
传统的钯的检测方法有:原子吸收光谱法、电感耦合等离子体质谱法等,这些方法具有花费昂贵、设备要求高、操作人员技术要求高的缺点。与这些检测方法相比,荧光探针因花费少,简便,灵敏度高,原位检测等优点日益成为化工、环境、生物等领域不可或缺的研究手段。因而,发展新型荧光探针具有较强的应用价值。
目前检测重金属钯的荧光探针存在以下不足:第一,大多数钯探针在有机溶剂或含有机溶剂的组分中检测,实用性降低;第二,一些重金属钯探针的检测温度要求严格,限制了探针的应用;第三,多数重金属钯探针不能做到紫外荧光同时有响应,不能肉眼识别,不利于推广应用。因而,发展新型检测重金属钯的有机小分子比色和荧光可视化探针,就有着重要的研究价值和科学意义。

上述检测零价钯的有机小分子探针的制备方法,包括以下制备步骤:将试卤灵钠盐、有机溶剂和三乙胺搅拌混合均匀,然后滴加氯甲酸烯丙酯,室温反应后萃取,浓缩有机相,即可得到所述检测零价钯的有机小分子探针。其合成路线图如图1所示。
所述的有机溶剂包括乙腈、四氢呋喃、二氯甲烷、N,N-二甲基甲酰胺等,优选二氯甲烷、四氢呋喃和N,N-二甲基甲酰胺。
优选地,所述的试卤灵钠盐、三乙胺和氯甲酸烯丙酯的摩尔比为1:(1.2~2):(1.2~2)。

上述有机小分子探针作为荧光探针用于零价钯的含量检测。
相对于现有技术,本发明具有如下优点及有益效果:

13CNMR(101MHz,CDCl3)δ186.24,153.57,152.40,149.26,148.50,144.37,135.24,134.80,131.31,131.23,130.65,120.14,118.54,109.09,107.33,69.73。
实施例2
本实施例的一种有机小分子探针(I)的合成,具体合成步骤如下:
将235mg的试卤灵钠盐(1.0mmol)加入到含有275μL三乙胺(2mmol)的二氯甲烷中(4ml)。室温搅拌下,将212μL氯甲酸烯丙酯(2mmol)缓慢滴加到上述溶液中。滴加完毕,室温反应12小时。反应完成后,加入水(100ml)和二氯甲烷(100ml)萃取,有机相再用水洗3次。收集有机相,加入无水硫酸镁干燥,浓缩,即可得有机小分探针(I)274mg,产率92%。产物鉴定数据同实施例1。
实施例3
本实施例的一种有机小分子探针(I)的合成,具体合成步骤如下:
将235mg的试卤灵钠盐(1.0mmol)加入到含有206μL三乙胺(1.5mmol)的四氢呋喃中(4ml)。室温搅拌下,将159μL氯甲酸烯丙酯(1.5mmol)缓慢滴加到上述溶液中。滴加完毕,室温反应12小时。反应完成后,加入水(100ml)和二氯甲烷(100ml)萃取,有机相再用水洗3次。收集有机相,加入无水硫酸镁干燥,浓缩,即可得有机小分子探针(I)253mg,产率85%。所得产物的核磁氢谱图和碳谱图同实施例1。
实施例4
探针(I)的紫外吸收强度随零价钯浓度的变化:
取Pd(PPh3)4和实施例1制备的有机小分子探针(I)各自溶于二甲亚砜中,配制成10mM储备液。取探针(I)储备液用PBS缓冲溶液(10mM,pH=7.40)稀释,配制成10μM的探针(I)溶液。采用紫外分光光度计测定其紫外吸收光谱。探针(I)与Pd(PPh3)4在室温下孵育30分钟后进行测试。随着Pd(PPh3)4的浓度增加,450nm处的吸光度逐渐降低,同时在570nm处出现了新的吸收峰。测试结果如图4所示。
实施例5
探针(I)的荧光发射强度随零价钯浓度的变化:
取Pd(PPh3)4和实施例1制备的有机小分子探针(I)各自溶于二甲亚砜中,配制成1mM储备液。取探针(I)储备液用PBS缓冲溶液(10mM,pH=7.40)稀释,配制成0.5μM的探针(I)溶液。采用荧光分光光度计测定在不同浓度的Pd(PPh3)4下的荧光光谱,探针(I)与Pd(PPh3)4在室温下孵育30分钟后进行测试。测试结果如图5所示。探针(I)在570nm激发下,荧光发射非常微弱,滴加Pd(PPh3)4后,590nm处出现一个新的发射峰,并随着Pd(PPh3)4浓度的增加,590nm处荧光强度逐渐增强。
实施例6
探针(I)对不同离子的选择性:
同实施例5待测液相同的配制方法配置荧光待测液,采用荧光分光光度计测定探针(I)与不同离子孵育下的荧光变化,探针(I)与Pd(PPh3)4在室温下孵育30分钟后进行测试。其中Pd(PPh3)4的最终浓度为1μM(2倍当量),其他金属离子的最终浓度为50μM(100倍当量)。测试方法同实施例5。测试结果如图6所示。由图6可看出,探针(I)与Pd(PPh3)4孵育后,590nm处的荧光发射强度明显增加,而与其他金属离子孵育后,荧光强度没有明显变化,说明探针(I)对零价钯具有很好的选择性响应。
实施例7
探针(I)对零价钯的可视化检测:
同实施例4待测液相同的配制方法配置两份待测液,进行可视化检测,往其中一份加入2当量的Pd(PPh3)4,室温孵育30min,进行肉眼观察和拍照。加入Pd(PPh3)4后,体系的颜色发生了非常显著的改变,由浅黄色变为粉红色(图7)。在紫外灯(365nm)照射下,探针(I)本身几乎没有荧光发射,加入2当量的Pd(PPh3)4的样品发出强烈的橙红色荧光(图8)。以上结果表明,探针(I)具有紫外和荧光双响应,并且可以通过裸眼观测颜色变化来快速检测零价钯。
上述实施例为本发明较佳的实施方式,但本发明的实施方式并不受上述实施例的限制,其它的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化,均应为等效的置换方式,都包含在本发明的保护范围之内。
