title: Selective fluorescence sensing of deoxycytidine 5'-monophosphate (dCMP) employing a bis(diphenylphosphate)diimine ligand.
abstract: A new bis(diphenylphosphate)diimine ligand (BP1) was prepared and evaluated for its ability for selective detection of deoxycytidine 5'-monophosphate (dCMP). BP1 exhibited off-type fluorescence in the presence of dCMP. The fluorescence of BP1 was significantly quenched upon the addition of 2.5 × 10(-4) M dCMP and the detection limit was 1.25 × 10(-5) M in MeCN-H(2)O (1:1, v/v). The binding ratio between BP1 and dCMP was determined to be 1:1 with the binding constant of 3.98 ± 0.60 × 10(-3) M(-1).
