Abstract

Building blocks with multiple components are promising for the synthesis of complex molecular assemblies, but are rarely available. Herein, we report a modification procedure for a multi-component building block [Ln3Ti(HSA)6(SA)4(H2O)] ({Ln3Ti-SA}, H2SA=salicylic acid, Ln=Eu/Gd) to form new building blocks {Ln3Tix-MSA} (H2MSA=5-methoxysalicylic acid, x=1, 2, 3) by constructing [Ti(MSA)3]2− units. The obtained {Ln3Tix-MSA} can further assemble into a chiral Ln22Ti14 ring with the formulae [Eu22Ti14(MSA)48(HMSA)22(CH3COO)4(H2O)10(iPrOH)] and [Gd22Ti14(MSA)46(HMSA)26(CH3COO)4(H2O)8]. Parallel experiments without Ti4+ result in linear Ln chains. Detailed analysis shows that the [Ti(MSA)4]4− unit makes the originally variable Ln chains become available building blocks and the modified [Ti(MSA)3]2− further triggers interesting chiral-sorting behavior. Finally, the electronic adsorption and magneto-optic responses of these molecular rings are investigated.
