Abstract

1-Phenylethynylpyrene fluorochrome was studied as meta- and para-derivatives of arabino-uridine-2'-carbamates in ss and dsDNA. 1-PEPy showed red-shifted emission and increased fluorescence quantum yield compared to pyrene. Although 1-PEPy has very short excited lifetime (<2.5 ns), it is able to form inter- and intrastrand excimers on DNA, probably resulting from spatial preorganization of two dye molecules.
