性质实验
1、吸收光谱实验
蒽醌衍生物PNDA对Cu2+的吸收光谱识别
图1是探针分子PNDA(实施例1)对Cu2+的选择性吸收光谱识别。在10mL浓度为0.1mmol/L探针分子PNDA溶液中分别加入10μL浓度为0.1mol/L(1倍摩尔量)的金属离子溶液(Ca2+、Na+、Ag+、Mg2+、Co2+、Al3+、Hg2+、Ni2+、K+、Cd2+、Pb2+、Zn2+、Cu2+)。实验中所使用的溶液体系均为乙腈/水(3:1,v:v)的混合溶液,吸收光谱在岛津UV-2450型紫外分光光度计上测定。
由图1可以看出探针分子PNDA(实施例1)在乙腈/水(3:1,v:v)的混合溶液中自身的吸收在373nm左右,当我们向探针分子溶液中加入过量的金属离子后,我们发现只有在加入Cu2+后,溶液的吸收红移至425nm左右,溶液的颜色也由黄绿色变为橙黄色,而当在探针分子溶液中加入其它金属离子时,则没有这一现象的发生,这说明该探针分子的吸收光谱对Cu2+有着独特的响应。
图2为Cu2+对探针分子PNDA(实施例1)的吸收光谱滴定图。在10mL浓度为0.1mmol/L探针PNDA溶液中依次加入0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9、1.0、1.2、1.5、2.0倍摩尔量的Cu2+。实验中所使用的溶液体系均为乙腈/水(3:1,v:v)的混合溶液,吸收光谱在岛津UV-2450型紫外分光光度计上测定。由图2可以看出,随着Cu2+的加入,溶液的吸收波长逐渐由373nm红移至425nm,当Cu2+加入量达到探针分子1倍摩尔量后,溶液的吸收波长不再移动,且峰的强度基本不变。这说明探针分子PNDA与Cu2+是1:1配位的。
2、荧光光谱实验
蒽醌衍生物PNDA对Cu2+的荧光识别
图3是探针分子PNDA(实施例1)对Cu2+的选择性荧光光谱识别。将探针分子PNDA溶于乙腈/水(3:1,v:v)的混合溶液中,配制成浓度为10μmol/L的溶液,在此溶液中分别加入1倍摩尔量的金属离子(Ca2+、Na+、Ag+、Mg2+、Co2+、Al3+、Hg2+、Ni2+、K+、Cd2+、Pb2+、Zn2+、Cu2+)。激发波长为420nm,测定溶液的荧光光谱。从图3中可以看出,探针分子溶液仅在550nm处有一个很弱荧光发射峰,在加入Cu2+后,溶液在490nm处出现了一个很强的荧光发射峰,而加入其它金属离子则没有这一现象,这说明该探针分子对Cu2+表现出非常强的荧光选择识别性。实验中所使用的溶液体系均为乙腈/水(3:1,v:v)的混合溶液,荧光光谱在AMINCO BowmanSeries 2荧光光谱仪上测得。
图4为Cu2+对探针分子PNDA(实施例1)的荧光光谱滴定图。在10μmol/L的探针分子PNDA的乙腈/水(3:1,v:v)的混合溶液中,分别加入0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9、1.0、1.2、1.5、2.0倍摩尔量的Cu2+。在420nm处激发,测量溶液的发射光谱,如图所示随着Cu2+的浓度增加,在490nm处出现一个新的荧光发射峰,并且荧光发射峰的强度随着Cu2+加入而不断增强,当Cu2+的加入量达到1倍摩尔量探针分子后,490nm处的发射峰强度基本不再增加。
图5为Cu2+与探针分子PNDA(实施例1)反应时间对溶液荧光强度的影响图。在10μmol/L的探针分子PNDA的乙腈/水(3:1,v:v)的混合溶液中,加入1倍摩尔量的Cu2+。在激发波长420nm,发射波长490nm处,分别在0、0.5、1.0、1.5、2.0、2.5、3.0、3.5、4.0、4.5、5.0分钟时记录溶液的荧光强度。如图所示,在探针分子PNDA溶液中加入Cu2+2分钟后,荧光强度达到最大值,且随着时间延长基本保持不变。
图6为当溶液中有其它共存金属离子时对探针PNDA(实施例1)选择性识别Cu2+的影响图。在10μmol/L的探针分子PNDA的乙腈/水(3:1,v:v)的混合溶液中,分别加入溶有10倍摩尔量的金属离子(Ca2+、Na+、Ag+、Mg2+、Co2+、Al3+、Hg2+、Ni2+、K+、Cd2+、Pb2+、Zn2+),在激发波长420nm,发射波长490nm处,测量溶液的荧光强度,然后再在上述溶液中加入1倍摩尔量的Cu2 +,在激发波长420nm,发射波长490nm处,测量溶液的荧光强度,从图6中可以看出,当溶液中大量存在其他金属离子时,探针分子PNDA对Cu2+的选择性识别并不受影响。
图7为不同pH值对探针PNDA(实施例1)选择性识别Cu2+的影响图。分别用不同浓度的盐酸或氢氧化钠溶液以调节10μmol/L的探针分子PNDA的乙腈/水(3:1,v:v)的混合溶液的pH值,在激发波长420nm,发射波长490nm条件下,测量探针溶液的荧光强度;然后再在以上溶液中分别加入1倍摩尔量的Cu2+,在激发波长420nm,发射波长490nm条件下,测量溶液的荧光强度。从图7中可以看出,在pH=5-10的范围内探针分子对Cu2+都具有很好荧光响应,并且比较稳定,这说明该探针可以在更宽泛的环境中检测Cu2+。
图8为探针PNDA(实施例1)在不同Cu2+浓度与荧光强度的线性关系图。从图中可以看出当Cu2+浓度在0.05-0.6mmol/L范围内呈现出良好的线性关系(R2=0.9983),纵坐标I为探针溶液中加入Cu2+后所测得的荧光强度,I0为探针溶液中未加入Cu2+后所测得的荧光强度,使用3σIUPAC标准计算所得的检测限为2.37×10-7mol/L。
