Abstract

Framework-isomeric three-dimensional (3D) Cd–Ln heterometallic metal–organic frameworks (HMOFs), {[Ln2(ODA)6Cd3(H2O)6]6 H2O}n (Ln=Gd (1 a) and Tb (1 b), ODA=oxydiacetic acid) and {[Cd(H2O)6][Ln2(ODA)6Cd2]H2O}n (Ln=Gd (2 a), Tb (2 b)), with neutral and anionic pores, respectively, were designed based on a lanthanide metalloligand strategy and synthesized by using a stepwise assembly and a hydrothermal method. Luminescence studies revealed that 1 b and 2 b can act as luminescent metal–organic frameworks and their light-emitting properties can be modulated by small guest molecules and the manganese counterion, respectively.
