The photoluminescent Ru(bpy):+ complex was dispersed in a polysiloxane film containing 2,2'-bipyridine (bpy) pendant groups. The unusually long photoluminescence lifetime of the Ru(bpy)i+ (1,94 ps at 25 "C) and the blue-shifted photoluminescent wavelength suggest a rigid polymer matrix. The fluoresc

## Abstract A new water‐insoluble polysiloxane containing pendant Ru(bpy) (bpy = 2,2′‐bipyridine) was studied with respect to the photoluminescence and its quenching by dioxygen. The emission was quenched by O~2~ in water more efficiently than in gas phase, and the Stern‐Volmer plots showed a downw
