TY  - JOUR
AB  - A new series of triphenylamine-based ligands with one (TPA1PY), two (TPA2PY) or three pending aza-macrocycle(s) (TPA3PY) have been synthesised and studied by means of pH-metric titrations, UV/Vis spectroscopy and fluorescence experiments. The affinity of these ligands for G-quadruplex (G4) DNA and its selectivity over duplex DNA were investigated by FRET melting assays, fluorimetric titrations and circular dichroism (CD) spectroscopy. Interestingly, the interaction of the bi- and specially the tri-branched ligand with G4 leads to a very intense red-shifted fluorescence emission band which may be associated with intermolecular aggregation between the molecule and the DNA. This light-up effect allows the application of the ligands as fluorescence probes to selectivity detect G4.
