The invention discloses a dinuclear ruthenium (II) complex as well as a preparation method and an application thereof as a living cell fluorescent dye. The dinuclear ruthenium (II) complex is characterized in that the cation part of the dinuclear ruthenium (II) complex is [(phen)2Ru(L)Ru(phen)2] and the structural formula is shown as the formula I in the specification; and the anion part of the dinuclear ruthenium (II) complex is (ClO4) or Cl. The dinuclear ruthenium (II) complex has excellent fluorescent characteristics and good cell membrane permeability, is a good living cell imaging reagent, simultaneously has bigger two-photon absorption interface, can color cytoplasm in the living cells without cell pretreatment and has good resistance to bleaching and a simple and stable structure. Cell viability experiment results show that the complex has lower cytotoxicity, causes slight cellular damage, has high coloring sensitivity and strong cell permeability and has great application potentials as a long-time single/two-photon cell imaging dye and a biological probe.
