文摘

To confirm how different anions influence sup-ramolecular self-assembly of lanthanide鈭抩rganic frameworks (LnOFs) as well as their luminescent properties, a new flexible achiral tripodal ligand, 1,1,1-tris-{[(2鈥?benzylaminoformyl)phenoxyl]methyl}ethane (L) and the LnOFs {[EuL(NO₃)₃]路1.5CHCl₃}_n and [EuL(pic)₃]_n have been designed and assembled. In the two LnOFs, {[EuL(NO₃)₃]路1.5CHCl₃}_n demonstrates an unprecedented chiral noninterpenetrated two-dimensional (2D) honeycomblike (6,3) (hcb, Schl盲fli symbol 6³, vertex symbol 6路6路6) topological network, and [EuL(pic)₃]_n confirms an unusual chiral LnOF with three-dimensional (3D) (10,3)-a (srs, SrSi₂, Schl盲fli symbol 10³, vertex symbol 10₂路10₄路10₄) topological framework. Also the anion-induced structures and energy transfer processes in the luminescence behavior of the two LnOFs were discussed in detail.
