Engineering Heteronuclear Arrays from IrⅢ-Metalloligand and CoⅡ Showing Coexistence of Slow Magnetization Relaxation and Photoluminescence
文献摘要：
Three heteronuclear IrⅢ-CoⅡ arrays,[Co(H2O)6]2[Ir(ppyCOO)(ppyCOOH)(bpy)]2[Ir(ppyCOO)2(bpy)]2(NO3)2·10.5H2O(2),[Co(H2O)6]{Co-(H2O)4[Ir(ppyCOO)2(bpy)]2}[Ir(ppyCOO)2(bpy)]2·15H2O(3)and{Co(H2O)2[Ir(ppyCOO)2(bpy)]2}·2CH3OH·3H2O(4),have been synthe-sized by combining paramagnetic CoⅡ ion with luminescent IrⅢ-metalloligand,[Ir(ppyCOOH)2(bpy)][Ir(ppyCOO)2(bpy)]·5H2O(1),where ppyCOOH=3-(pyridin-2-yl)benzoic acid and bpy=2,2'-bipyridyl.Owing to the variable charged states of compound 1 at dif-ferent pH,compounds 2 and 3 are discrete ionic complexes containing hydrated Co2+cations and deprotonated[Ir(ppyCOO)2(bpy)]-anions as well as coexisting neutral[Ir(ppyCOO)(ppyCOOH)(bpy)](for 2)or Co(H2O)4[Ir(ppyCOO)2(bpy)]2 trinuclear molecule(for 3).Whereas compound 4 consists of self-assembled two-dimensional coordination polymer with Co-metalloligand dative bonds.The hexa-coordinated CoⅡ cores in all complexes display octahedral geometries with varying degrees of distortion.In a bias dc field,the ac susceptibilities for 2-4 reveal slow magnetic relaxation.Moreover,the solid-state phosphorescence is observed for compounds 2 and 3 due to weak supramolecular interaction between CoⅡ ion and Ir-moiety but is severely quenched for 4,where the Co center is strongly connected to the metalloligand.To the best of our knowledge,this is the first report of Ir-Co systems showing both slow magnetization relaxation and photoluminescence.
