title: [2- and 4-phenylethynylpyrenes--new fluorescent labels for DNA].
abstract: It was shown by the example of 1-, 2-, and 4-phenylethynylpyrene 2'-arabino-carbamate derivatives of uridine that the position of pyrene substitution substantially affects the spectral and photophysical properties of the fluorophore and its ability to interact with the nucleic base.
