title: [Mechanisms for changing fluorescent properties of bis-benzimidazole dyes].
abstract: Spectral properties of a series of externally binding substrate-specific bis-benzimidazole dyes that were either bound or not bound to DNA were studied. Feasible mechanisms of variation in fluorescent properties of the dyes under study were considered depending on their chemical structure. Contribution of the rotational diffusion and the donor-acceptor interactions to the prediction and explanation of fluorescent properties of the substrate-specific dyes was discussed.
