Popis:	Absorption spectra, emission spectra (90 and 298 K), luminescence lifetimes, luminescence quantum yields, and photochemical behavior of a semicage bipyridazine (bpdz) Ru(II) complex K6 and related open-chain bpdz model complexes K1-4 have been studied and compared with those of Ru(bpy)[sub 3][sup 2+] K5. The absorption bands in the visible spectra of K1-4 and Ru-podate K6 are close in energy to the corresponding bands of Ru(bpy)[sub 3][sup 2+], whereas the emission bands are slightly red shifted. The luminescence lifetimes of K1-4/K6 (1500-3400 ns) are longer than that of K5 (600 ns). The open-chain bpdz model complexes K1-4 and especially K6 are highly photoinert ([phi][sub p] [
