Effects of template molecules on the structures and luminescence intensities of a series of porous Tb-MOFs based on the 2-nitroterephthalate ligand.

ABSTRACT: Four novel porous Tb(iii) metal-organic frameworks (Tb-MOFs) have been designed and prepared hydrothermally from 2-nitroterephthalate (2-H₂ntp), namely {[Tb(2-ntp)_1.5(H₂O)]·H₂O} _n (1), {[Tb(2-ntp)₂(H₂O)]·4,4'-Hbipy} _n (2), {[Tb(2-ntp)₂(H₂O)]·2,4-Hbipy} _n (3), and {[Tb(2-ntp)₂(H₂O)]·(1,4-H₂bbi)_0.5} _n (4) (4,4'-bipy = 4,4'-bipyridine; 2,4-bipy = 2,4-bipyridine; 1,4-bbi = 1,4-bisbenzimidazole). X-ray diffraction structural analyses show these Tb-MOFs are porous and are based on Tb³⁺ ions and 2-nitroterephthalate, in which water molecules (1) or protonated N-donor ligands (2-4) exis
