Selective sensing of phosphates derivatives, including nucleotides and inorganic phosphates, is high on the targets list due to their pivotal role in biological systems. In this NJC paper, Kumaresh Ghosh et al. (University of Kalyani, India) have designed a simple pincer-like receptor that selectively recognises tetra- butylammonium dihydrogenphosphate in CH3CN over a series of other anions by exhibiting characteristic excimer emission in fluorescence. Also the simple receptor 1 fluoro- metrically distinguishes ATP from ADP and AMP in aqueous CH3CN.
