Abstract

Photoluminescent Ru(bpy) 2+3 complex was covalently anchored on a polysiloxane chain, and photoluminescence of the film was studied. The emission yield becomes lower with higher probe concentration indicating concentration quenching. The intermolecular distance distribution of the probe was obtained by statistical analysis, and the distance for static concentration quenching was 0.83 nm.
