Quinoxalino[2′,3′:9,10]phenanthro[4,5-abc]phenazine (QPP) dyes have been studied as electron acceptor materials, fluorophores, and building blocks for self-organizing organic semiconductors.

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 ...
