Colorimetric and fluorescence 'turn-on' recognition of fluoride by a maleonitrile-based uranyl salen-complex

The synthesis and characterization of two new uranyl-salen complexes, 1-2, based on a 1,2-diaminomaleonitrile unit, is described. Spectroscopic studies to evaluate their potential as colorimetric probes for fluoride detection in chloroform and dichloromethane were undertaken. Compound 2 exhibits a &...
