Abstract
A highly water soluble copper(II) complex, 1 of a fluorophore ligand 4-(2-hydroxybenzylamino)-5-hydroxynaphthalene-2,7-disulfonic acid (FL1) was synthesized and characterized. In the complex, the fluorescence intensity of the ligand was found to quench due to the presence of paramagnetic Cu(II) center. In degassed methanol solution of complex 1, the Cu(II) center was found to undergo reduction in presence of nitric oxide. This resulted in the simultaneous formation of N-nitrosated ligand. In the process, the quenched fluorescence intensity of the ligand restored. The selective turn on fluorogenic nature of the complex 1 was used to study the endogenously produced NO in living cells.
