设计、合成一种新型萘酰亚胺与香豆素偶联的铜离子化学传感器1.通过1H NMR,13C NMR,IR,ESI-MS等表征该物质的化学结构,通过UV-vis吸收光谱研究该分子的光谱性质.结果表明:该分子在DMSO-H2O(体积分数为1:1)溶液中加入铜离子,传感器分子通过与铜离子络合导致溶液颜色从黄色变成橙黄色.不仅最大吸收波长有较明显地红移且其吸收强度也增强,而加入其他离子(Al3+、Ca2+、Cd2+、Ba2+、Hg2+、Sr2+、K+、Mn2+、Co2+、Ni2+、Ag+、Mg2+、Li+、Pb2+、Zn2+)均没有明显变化,该传感器具有专一性好、灵敏度高、检测迅速且铜离子而不受其他离子的干扰.

Designed and synthesized a new copper ion chemosensor 1 based on naphthalimide and coumarin. The chemical structure of sensor 1 was investigated by 1 H NMR,13C NMR,IR,ESI-MS,the spectral properties of the molecule were studied by UV-vis,which showed that the solution color changed from yellow to orange due to sensor 1 with copper ion complexion when the copper ion was added to the solution of sensor 1 in DMSO-H2O(V/V=1:1). The maximum absorption wavelength not only had the obvious red shift but also had an enhancement,however,when the other ions were added,such as Al3+、Ca2+、Cd2+、Ba2+、Hg2+、Sr2+、K+、Mn2+、Co2+、Ni2+、Ag+、Mg2+、Li+、Pb2+、Zn2+,the maximum absorption wavelength did not show any change. These results revealed that the sensor 1 had high specificity,sensitivity,fast detection for copper ion and there was almost no interference from other metal ions.
