Title: Positional isomerism-driven two 3D pillar-layered metal-organic frameworks: Syntheses, topological structures and photoluminescence properties

Abstract

Two novel three-dimensional (3D) pillar-layered metal-organic frameworks (MOFs), namely [Zn{sub 2}(μ{sub 2}-OH)(boaba)(1,4-bmimb)]{sub n} (1) and {[Zn_5K_2(μ_2-H_2O)_2(boaba)_4(1,2-bmimb)_2(H_2O)_2]·H_2O}{sub n} (2), were prepared by hydrothermal reactions (H{sub 3}boaba=3,5-bis-oxyacetate-benzoic acid; 1,4-bmimb=1,4-bis((2-methyl-1H-imidazol-1-yl)methyl)benzene; 1,2-bmimb =1,2-bis((2-methyl-1H-imidazol-1-yl)methyl)benzene). Notably, 1 exhibits a (3,5)-connected binodal (6{sup 3})(6{sup 9}·8)-gra net with binuclear [Zn{sub 2}(μ{sub 2}-OH)(COO)]{sup 2+} clusters, while 2 shows a novel (4,4,5,9)-connected 4-nodal net constructed from the unique Zn(II)-K(I) heterometal rod-like substructures. The results indicate that the disposition of the 2-methylimidazolyl groups of bis(imidazole) ligands have a significant effect on structural diversity. Moreover, the photoluminescence properties of 1 and 2 have been investigated. - Graphical abstract: Two novel 3D pillar-layered metal-organic coordination networks with aromatic multicarboxylate anion and bis(imidazole) ligands have been synthesized and structurally characterized. Display Omitted - Highlights: • It is rarely reported that metal-organic frameworks prepared with 3,5-bis-oxyacetate-benzoic acid. • Two metal-organic frameworks based on positional isomeric ligands were synthesized and structurally characterized. • Compond 1 displays unique (3,5)-connected binodal gra topology. • Compound 2 exhibits (4,4,5,9)-connected 4-nodal topology based on the Zn(II)-K(I) heterometal rod-like substructures. • The photoluminescence properties of compound 1 and 2 have been investigated.

  • To explore the possibility of obtaining the metal-organic frameworks (MOFs) bearing the bsgluH{sub 2} ligand, two new Cd(II) and one Cu(II) coordination polymers, [Cd(bsglu)(bipy)] {sub n} (1), [Cd(bsglu).(H{sub 2}O)] {sub n} (2) and {l_brace}[Cu{sub 2}(bsglu){sub 2}(bipy){sub 2}].4H{sub 2}O{r_brace} {sub n} (3) (bsglu=N-benzesulfonyl-glutamic acid bianion, bipy=2,2'-bipyridine) were synthesized and characterized by IR, elemental analysis and X-ray diffraction analysis. Compounds 1 and 3 exhibit one-dimensional coordination chains, which are further connected to form two-dimensional supramolecular networks through {pi}-{pi} aromatic stacking interactions in a novel zipper-like way. Compound 2 presents a two-dimensional layer structure. To the best of our knowledge, 2 is themore » first two-dimensional complex formed from transition metal and bsgluH{sub 2} ligand. Interestingly, the bsglu anion exhibits remarkable versatile coordination modes in these complexes. Fluorescent analyses show that 1 exhibits photoluminescence in the solid state. Magnetic measurements for 3 revealed that the Cu(II) chain exhibit a weak antiferromagnetic behavior with a J value of -0.606 cm{sup -1}. - Graphical abstract: Three new complexes, [Cd(bsglu)(bipy)] {sub n} (1), [Cd(bsglu).(H{sub 2}O)] {sub n} (2) and {l_brace}[Cu{sub 2}(bsglu){sub 2}(bipy){sub 2}].4H{sub 2}O{r_brace} {sub n} (3), constructed from Cd(II) or Cu(II) salt with N-benzesulfonyl-glutamic acid were synthesized and characterized.

  • A series of lanthanide-organic frameworks with aromatic pyridinecarboxylate ligand, generally formulated as [Ln(PYDC)(C{sub 2}O{sub 4}){sub 0.5}(H{sub 2}O){sub 2}].H{sub 2}O (Ln=Pr(1), Nd(2), Eu(3), Gd(4), Tb(5), Er(6); H{sub 2}PYDC=3,4-pyridinedicarboxylic acid) have been successfully synthesized and characterized. Their isostructures are built up from one-dimensional (1D) infinite chains cross-linked via the tri-connected PYDC ligands, leading to the two-dimensional (2D) layer structure. The adjacent layers are further extended into three-dimensional (3D) supramolecular frameworks through hydrogen bonding and {pi}-{pi} stacking interactions. Interestingly, the oxalate bridging ligand is believed to form via in situ ligand synthesis through decarboxylation of the organic precursor, H{sub 2}PYDC. Complexes 3 andmore » 5 exhibit strong fluorescent emissions in the visible region at room temperature. - Graphical abstract: A series of lanthanide-organic frameworks with aromatic pyridinecarboxylate ligands have been successfully synthesized and characterized.
