Description
技术领域:
本发明涉及有机小分子荧光探针领域,具体涉及一种基于BODIPY的钯离子荧光探针化合物及其合成方法。
背景技术:
在现代工业合成方法中,重金属广泛应用于不同领域的化合物与聚合物材料制备,其中,钯(Pd)作为最广泛使用的金属负载型催化剂,应用尤为普遍。此外,钯也是电子产品、珠宝、航空航天、医疗器械、燃料电池等行业不可或缺的关键材料。工业生产所排放的钯对土壤、水资源造成污染,对生态系统和人类健康构成了严重威胁。因此,开发有效的方法来检测工业、制药业和环境样品中的钯含量非常必要。
相较于仪器检测钯含量的方法如原子吸收光谱法(AAS)、电感耦合等离子体质谱(ICP-MS)、固相微萃取结合高效液相色谱(SPME-HPLC)、X射线荧光等,荧光探针具有操作简单,响应快速,选择性好,灵敏度高等特点,能够实时实地进行检测。其中,氟硼二吡咯(BODIPY)荧光染料具有高摩尔消光系数(ε>70 000M-1cm-1)和荧光量子产率(ΦF约0.5-0.8),易于化学修饰,吸收发射波长可调,光热稳定性高等优点,被广泛应用于各种离子、小分子检测与生物荧光成像((a)Ulrich,G.;Ziessel,R.;Harriman,A.Angew.Chem.Int.Ed.2008,47(7),1184-1201;(b)Kowada,T.;Maeda,H.;Kikuchi,K.Chem.Soc.Rev.2015,44(14),4953-4972;(c)Kolemen,S.;Akkaya,E.U.Coord.Chem.Rev.2018,354,121-134.)。近年来,文献报道了多例基于罗丹明B,荧光素,香豆素,花青染料,苝二酰亚胺(PDI)等不同荧光团的钯离子荧光探针(Balamurugan,R.;Liu,J.-H.;Liu,B.-T.Coord.Chem.Rev.2018,376,196-224.)。但目前基于BODIPY的钯离子荧光探针并不多((a)Kaur,P.;Kaur,N.;Kaur,M.;Dhuna,V.;Singh,J.;Singh,K.RSCAdv.2014,4(31),16104-16108;(b)Keum,D.;Kim,S.;Kim,Y.Chem.Commun.2014,50(10),1268-1270;(c)Li,Y.;Yang,L.;Du,M.;Chang,G.Analyst 2019,144(4),1260-1264.)。
总的来看,文献所报道的BODIPY探针大都基于荧光猝灭的ON-OFF识别机制,容易受其他环境因素干扰;探针灵敏度与对钯离子的选择性尚待提高。鉴于钯离子对环境与生态系统的危害,以及目前所报道探针的局限性,结合BODIPY染料分子优异的光物理化学性能,设计制备高灵敏度、高选择性的BODIPY基钯离子荧光探针具有研究价值与应用前景。
发明内容:
本发明旨在针对现有技术存在的问题,提供一种基于BODIPY的钯离子荧光探针化合物及其合成方法,该钯离子荧光探针化合物用于钯离子快速检测,探针具有高选择性、高灵敏度和响应迅速的特点。

实施例4
荧光探针光物理性质测试:
配制实施例3得到的钯离子荧光探针化合物BDP-Pd的原液,溶剂为DMSO,浓度为2mM。取10μL钯离子荧光探针化合物BDP-Pd原液稀释于4mL乙腈中(浓度为5μM),测试紫外-可见吸收与荧光发射光谱。荧光发射光谱测试中,激发波长为475nm。
实验结果:由图3可以得出,钯离子探针化合物的最大吸收波长为497nm(logε=4.82),最大发射波长为510nm(ФF=0.01)。可见,由于BODIPY meso位氮原子向染料中心的分子内光激发电子传递过程(PeT),化合物荧光极弱,处于“OFF”状态。
实施例5
荧光探针响应时间测试:
氯化钯原液溶剂为H2O:DMSO(v/v=9:1)。测试溶剂为乙腈,其中钯离子荧光探针化合物的浓度为5μM,钯离子浓度为20μM。钯离子加入后,每隔1min记录混合液的荧光发射谱图。以钯离子荧光探针化合物在508nm处的荧光强度变化(ΔI/I0)与时间作图。
实验结果:由图4可以得出,向探针溶液加入钯离子后,能立即引起15倍的荧光增强;五分钟之内荧光趋于稳定,达初始荧光强度的34倍,探针荧光处于“ON”状态。荧光探针对目标检测物钯离子响应迅速,前后荧光变化明显,十分有利于判定。
实施例6
探针化合物与钯离子的络合比判定:
实验采用经典的Job’s plot法,钯离子荧光探针化合物与钯离子的总浓度为10μM。测定不同浓度比下混合液的荧光发射谱图。以钯离子荧光探针化合物在508nm处的荧光强度变化(ΔI)对[Pd2+]/([Pd2+]+[BDP-Pd])作图。
实验结果:由图5可以得出,经判定,钯离子荧光探针化合物与钯离子的络合比为1:2。
实施例7
钯离子对荧光探针溶液的滴定测试:
测试溶剂为乙腈,钯离子荧光探针化合物的浓度为5μM,滴入0-10μM的钯离子,等待五分钟后,记录混合溶液的荧光发射谱图,激发波长为475nm。如图6~8所示。
实验结果:随着钯离子的加入,钯离子荧光探针的荧光发射逐渐增强,呈线性增长,随后变化趋于缓慢。钯离子可以与荧光探针分子的氮原子与氧原子配位,从而阻碍分子内光激发电子传递过程,致使探针荧光恢复,随着钯离子的加入,荧光逐渐增强。
荧光探针检测限:
基于荧光滴定测试的结果,以探针在508nm处的荧光增量ΔI对钯离子浓度(0-5μM)作图。荧光强度变化与钯离子浓度呈线性关系,探针对钯离子的检测限可由公式:检测限=3xσ/K计算,其中,σ为空白样品的标准方差值,K为直线斜率。经计算,本发明所述的荧光探针对钯离子的检测限低至0.72ppb,通过文献调研,为目前所报道的检测限最低的BODIPY钯离子荧光探针。
荧光探针与钯离子的络合常数:
基于1:2的主-客体络合比,络合常数可由以下公式进行计算:
其中,[H]0和[G]0分别为主客体的初始浓度,ΔI为探针的荧光强度变化,Δεa为主客体络合前后的发射系数变化。主-客体的络合常数可由[H]0[G]0 2/ΔI对[G]0([G]0+4[H]0)作图计算。经计算,本发明所述的荧光探针与钯离子的络合常数为8.5×1010M-2。
实施例8
荧光探针对钯离子的选择性:
实验选取了容易对钯离子检测造成干扰的19种金属阳离子,包括:Na+,K+,Cd2+,Ca2 +,Mg2+,Ag+,Mn2+,Pt2+,Cu2+,Fe3+,Fe2+,Zn2+,Ba2+,Cd2+,Co2+,Hg2+,Pb2+,Al3+,Cr3+。各金属阳离子的浓度均为20μM。测试溶剂为乙腈,探针化合物的浓度为5μM,加入金属离子后,混合均匀,静置五分钟,测试溶液的荧光发射光谱。
如图9~11所示,实验结果:由荧光发射光谱可知,探针只对钯离子表现出明显的荧光增强信号响应,选择性高,抗干扰能力强。由图11可知,探针溶液加入钯离子前后在手持紫外灯365nm波长下颜色变化明显,说明该探针可实现钯离子的肉眼快速判定。
上列详细说明是针对本发明之一可行实施例的具体说明,该实施例并非用以限制本发明的专利范围,凡未脱离本发明所为的等效实施或变更,均应包含于本案的专利范围中。
