Abstract
The quenching of the luminescence intensity and lifetime of the electronically excited species Ru(bipy)32+ by a series of copper (II) cyclodextrin complexes is studied. It is found that conventional Stern-Volmer behaviour is not followed. A modified version of the Stern-Volmer equation, one which assumes purely static quenching, is in good agreement with experimental data. Inclusion of the Ru(bipy)32+ by the metallo-cyclodextrin complex is observed to play a key role in the quenching mechanism.
