title: Assembly of framework-isomeric 4d-4f heterometallic metal-organic frameworks with neutral/anionic micropores and guest-tuned luminescence properties.
abstract: Framework-isomeric three-dimensional (3D) Cd-Ln heterometallic metal-organic frameworks (HMOFs), {[Ln2 (ODA)6 Cd3 (H2 O)6 ]⋅6 H2 O}n (Ln=Gd (1 a) and Tb (1 b), ODA=oxydiacetic acid) and {[Cd(H2 O)6 ]⋅[Ln2 (ODA)6 Cd2 ]⋅H2 O}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.
