| Abstract: Four of two branched bis-2,4-dinitrophenylhydrazones were prepared as colorimetric anion receptors, which recognize F- and H2PO4- selectively in solution of DMSO through hydrogen binding. Single crystal of one of the compounds was obtained (CCDC: 298951). The UV-Vis titration with F- or H2PO4- revealed that new intense absorption bands for all of receptors accompanied by dramatic color changes with the association constants in the range of 104～105 L·mol-1. The UV-Vis and 1H NMR investigation indicated that the hydrogen bonds were formed between F- or H2PO4- and receptors, and there was also a deprotonation of binding fragment during the hydrogen bond formation in the case of F-. |
