Abstract：

Self-assembly　is　an　important　strategy　to　construct　supramolecular　frameworks.　Small　change　in　the　assembling　units　often　leads　to　significant　variations　in　the　self-assembly　structures.　In　the　work,　we　obtain　two　supramolecular　frameworks　assembled　by　different　[EuL2]3+　units　(L　=　tris((5,6-dimethyl-1H-benzo[d]imidazol-2-yl)methyl)　amine).　One　meso　compound　{[EuⅢL2]·(H2O)6·Cl3}　(Meso-EuL2)　is　assembled　by　an　achiral　meso-[EuL2]3+　unit,　forming　a　supramolecular　three-dimensional　framework　through　six-fold　intermolecular　π‒π　interactions.　The　other　is　a　racemic　compound　{[EuⅢL2]·(CH3OH)5·Cl3}　(Rac-EuL2),　assembled　by　two　chiral　rac-[EuL2]3+　units　predominantly　via　hydrogen　bonding,　leading　to　a　layered　supramolecular　framework.　The　luminescent　properties　are　different　between　Meso-EuL2　and　Rac-EuL2,　with　Meso-EuL2　exhibiting　more　excimer-like　emissions,　which　is　likely　caused　by　its　stronger　π‒π　interactions　in　the　structure.　©　2024
