Abstract

The creation of cascade processes, e.g., triggering the quenching of multiple luminescent centers in response to quenching at a single site, is an important amplification approach for sensing biomolecules with specificity and high sensitivity. Two processes can be important contributors to super quenching within luminescent polymers (1). First, a single acceptor may quench the fluorescence emission from an entire macromolecule in aqueous solution. Second, where the luminescent polymer is charged, a weakly bound complex between the polyelectrolyte and quencher may form enabling static super quenching. Polymers labelled with ruthenium polypyridyl complexes represent attractive systems for exploring super quenching because emission from the metalto-ligand charge transfer (MLCT) excited states of Run can be probed with great sensitivity (2).
