摘要:
Photosubstitution and/or photoisomerization in cis-[Ru(bpy)(2)(py)(2)](PF6)(2) and trans-[Ru(bpy)(2)(4Etpy)(2)](PF6)(2) or the molecular assemblies cis-[Ru(bpy)(2)(MQ(+))(2)](PF6)(4) and trans-[Ru(bpy)(2)(MQ(+))(2)](PF6)(4) are greatly inhibited in the rigid matrixes poly(methyl methacrylate) (PMMA) films and silica sol-gel monoliths. There can also be profound changes in photophysical properties as illustrated below for emission from cis-[Ru(bpy)(2)(py)(2)](PF6)(2) in CH3CN and in the silica sol-gel.GRAPHICS
