The ratiometric fluorescence chemodosimeter N-butyl-4-(prop-1-en-1-yloxy)-1,8-naphthalic anhydride (NT-VE) was designed for Hg2+ recognition by oxymercuration at ambient temperature with high selectivity and no interference from other metal cations such as Cu2+, Ag+, Au3+, Fe3+, etc. The NT-VE could be incorporated into sodium dodecyl-benzenesulfonate (SDBS) micelles, which was confirmed by the clear
比例荧光化学计量仪N-丁基-4-(丙-1-烯-1-基氧基)-1,8-萘酐(NT-VE)设计用于在环境温度下以高选择性,无选择性地通过氧化汞进行Hg 2+识别。从其它金属阳离子如Cu干扰2+,银+,金3+,铁3+,等等的NT-VE可并入其通过所观察到的清楚的发射增强证实钠十二烷基苯磺酸盐(SDBS)胶束,在0.1 mM SDBS中。SDBS的疏水核增强了NT-VE的溶解度,可检测Hg 2+在水溶液中,带负电荷的胶束表面增加了Hg 2+的局部浓度,从而增强了灵敏度。这项工作证明了NT-VE化学溶度计在水溶液中Hg 2+的比例检测中具有出色的性能。NT-VE / SDBS系统可以在0.05–10μM的线性范围内检测到Hg 2+,在水中的检测限为9 ppb(45 nM)。
