Topology‐Selective, Fluorescent “Light‐Up” Probes for G‐Quadruplex DNA Based on Photoinduced Electron Transfer

Six novel probes were prepared by covalent attachment of a G4‐DNA ligand (bis(quinolinium) pyridodicarboxamide; PDC) to various coumarin or pyrene fluorophores. In the absence of DNA, the fluorescence of all probes is quenched due to intramolecular photoinduced electron transfer (PET), as evidenced...
