检测和测量氨的浓度是许多科技领域感兴趣的问题。合成了一种卟啉基钴（II）配合物，并对其作为一种“开启”荧光氨传感器进行了研究。NH3对[Co(TPF)(Ds-pip)]传感器溶液处理后，荧光发射增加了六倍以上，这是由于NH3引起轴向配位荧光团的位移。(C) 2011 Elsevier Ltd.版权所有。
Detecting and measuring the concentration of ammonia is of interest in many scientific and technological areas. A porphyrin based cobalt(II) complex with a dansyl fluorophore has been synthesized and investigated as a 'turn-on' fluorescent ammonia sensor. Over sixfold increase in fluorescence emission occurs upon the treatment of NH3 to [Co(TPF)(Ds-pip)] sensor solution, resulting from NH3-induced displacement of the axially coordinated fluorophore.
