Ruthenium (II) complex‐containing polymers were prepared and characterized by absorption and luminescence spectra, luminescence quantum yield, and luminescence lifetime. The polymers are Ru(bpy) 2 (poly‐6‐vinyl‐2,′2‐bipyridine)CI 2 ( 1 ) and Ru(bpy) 2 (poly‐4‐methyl‐4′‐methyl‐4′ ‐vinyl‐2,2′‐bipyridine)CI 2 ( 2 ). The absorption spectra and luminescence spectra of polymers 1 and 2 were substantially the same as that of Ru(bpy) 3 CI 2 . The lifetime of polymers 1 and 2 was similar to that of the respective monomer model compounds. The lifetime of polymer 1 was very short (ca. 13 ns) in comparison to Ru(bpy) 3 CI 2 (660 ns), whereas the lifetime of polymer 2 (660 ns) was similar to that of Ru(bpy) 3 CI 2 . The temperature‐dependency of the lifetime was discussed in terms of Watts' model.
