1-Phenylethynylpyrene (1-PEPy) as refined excimer forming alternative to pyrene: Case of DNA major groove excimer
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 (
