Metal-induced pre-organisation for anion recognition in a neutral platinum-containing receptor.
The presence of Pt(II) allows pre-organisation of 4,4'-dicarboxamidoindole-2,2'-bipyridine, enhancing anion affinity with the resulting complex displaying selectivity for dihydrogen phosphate in DMSO-d6-0.5% water. Moreover the Pt(II) complex behaves as a colorimetic sensor for fluoride.
