title: Ortho-phenylenediamine-based open and macrocyclic receptors in selective sensing of H2PO4(-), ATP and ADP under different conditions.
abstract: Ortho-phenylenediamine-based open and macrocyclic receptors have been designed and synthesized. The open receptor 1 and the macrocyclic receptor 2 fluorimetrically distinguish H(2)PO(4)(-) from the other anions examined in CH(3)CN with appreciable binding constant values. As practical applications, they are also sensible to nucleotides in aq. CH(3)CN (1 : 1, v/v). The receptor 1 shows significant emission change upon complexation of ATP and ADP. ADP is selectively distinguished by a ratiometric change in emission. In contrast, the macrocyclic receptor 2, under similar conditions, shows good binding with ATP over the others.
