英文摘要	Stable nanoscale cross-linked polymer micelles containing Ru complexes (Ru-CMs) were prepared from monomethoxy[poly(ethylene glycol)]-block-poly(L-lysine) (MPEG-PLys) and [(bpy)(2)Ru(fmbpy)](PF6)(2) (bpy=bipyridine, fmbpy=5-formy-5-methyl-2,2-bipyridine). To stabilize the micelles, bifunctional glutaraldehyde was used as a cross-linker to react with the free amino groups of the PLys block. After that, the Ru-CMs showed very good stability in common solvents. The Ru-CMs showed photocatalytic activity and selectivity in the oxidation of sulfides that were as high as those of the well-known [Ru(bpy)(3)(PF6)(2)] complex, because the micelles were swollen in the methanol-sulfide mixture. Moreover, because of the nanoscale size of the particles and their high stability, the Ru-CM photocatalysts can be readily recovered by ultrafiltration and reused without loss of photocatalytic activity. This work highlights the potential of using cross-linked micelles as a platform for developing highly efficient heterogeneous photocatalysts for a number of important organic transformations.
