利用光辐照界面的电喷雾电离质谱仪，成功地研究了冠醚孔雀绿明腈衍生物在溶液中的金属离子络合和光离。质谱分析清楚地表明，孔雀石绿衍生物的电中性形式可以将金属离子与其冠醚部分络合。在紫外光照射下，检测到孔雀石绿衍生物电离为相应的阳离子形式，并伴随着金属离子从其冠醚部分排斥。质谱仪还发现了在不同溶剂中不同的光电离行为，这是其他分析技术很难检测到的。
Electrospray-ionization mass spectrometry using a photoirradiation interface has been successfully applied to the investigation of metal-ion complexation and photoionization of crowned Malachite Green leuconitrile derivatives in solution. The mass spectrometry clearly showed that the Malachite Green derivatives in their electrically neutral forms can complex metal ions with their crown ether moiety. Ionization of the Malachite Green derivatives to their corresponding cationic forms, accompanied by metal-ion repelling from their crown ether moiety, was detected upon UV-light irradiation. A remarkably different photoionization behavior in various solvents, which is difficult to detect by other analytical techniques, was also found by the mass spectrometry.
