From lamellar net to bilayered-lamella and to porous pillared-bilayer: Reversible crystal-to-crystal transformation, CO2adsorption, and fluorescence detection of Fe3+, Al3+, Cr3+, MnO4-, and Cr2O72-in water

An aqua-coordinated lamellar net [Zn(5-NH2-1,3-bdc)(H2O)] (1, 5-NH2-1,3-H2bdc = 5-amino-1,3-benzenedicarboxylic acid) has been found to undergo a reversible stimuli-responsive 2D-to-2D crystal-to-crystal transformation with a water-free bilayered-lamellar net [Zn(5-NH2-1,3-bdc)] (1′) upon removal and rebinding of aqua ligands, whereas a 2D porous pillared-bilayer [Zn2(5-NH2-1,3-bdc)2(NI-bpy-44)]·DMF (2, NI-bpy-44 = N-(pyridin-4-yl)-4-(pyridin-4-yl)-1,8-naphthalimide) has been tailored by introducing NI-bpy-44 to replace the coordinated aqua ligands. Pillared-bilayer 2 displayed a moderate CO2 uptake of 79.1 cm3 g-1 STP at P/P0 = 1 and 195 K with an isosteric heat of CO2 adsorption (Qst) of 37.0 kJ mol-1 at zero-loading. It is noteworthy that the water suspensions of 1 and 2 both displayed good fluorescence performances, which were effectively quenched by Fe3+, MnO4-, and Cr2O72- ions and shifted to long wavelengths by Fe3+, Al3+, and Cr3+, even with the coexistence of equal amounts of most other interfering ions. Taking the Stern-Volmer quenching constant, limit of detection, quenching efficiency, anti-interference ability, and visual observation into consideration, it is clear that both 1 and 2 are promising and excellent fluorescent sensors for highly sensitive detection of Fe3+, MnO4-, and Cr2O72-.

An acid-base resistant Zn-based metal-organic framework as a luminescent sensor for mercury(II)

A monocyclic organic ligand 5-aminoisophthalic acid (H2APA) with one amino and two carboxylic groups, has been employed to construct a stable Zn-based metal-organic framework, ZnAPA. It features a 3D supramolecular network containing the pores

Fluorescence detection of aromatic amines and photocatalytic degradation of rhodamine B under UV light irradiation by luminescent metal-organic frameworks

The detection of trace amounts of aromatic amines is significantly important for security concerns and pollution control. Two multifunctional metal-organic frameworks (MOFs), [ZnL·H2O]n (1) and [CdL·H2O]n·2nHsu

Room temperature phosphorescence of Mn(ii) and Zn(ii) coordination polymers for photoelectron response applications

Room temperature phosphorescence of Mn(ii) and Zn(ii) based coordination polymers (Mn-CP and Zn-CP) with a different mechanism was confirmed by experiments and theory calculations. The Mn-CP exhibits high photoelectron response performance while Zn-CP can generate frequency tunable alternating current when the period of on-off illumination is changed.

Porous metal-organic frameworks with 5-aminoisophthalic acid as platforms for functional applications about high photodegradation efficiency of phenol

Four novel complexes, [CoL(H2O)] (1), [ZnL(H2O)] (2), [Ni- (HL)2(H2O)2]2H2O (3), and [CdL(H2O)]H2O (4) (L = 5-aminoisophthalic acid), were successfully synthesized by the reaction of transition metal salts and 5-aminoisophthalic acid at hydrothermal conditions. The four complexes were characterized by element analysis, infrared spectra, UV-vis spectra, powder X-ray diffraction analysis, and thermogravimetric analysis. X-ray single-crystal diffraction analysis showed that the four complexes were 3D network structures and contained pores with sizes of 7.05 to 14.67 ?. In addition, we investigated the photodegradation ability of the four complexes for phenol solution under UV irradiation. The results showed that the four complexes had a different degree of degradation ability to phenol solution. At the same time, we found that the degradation process was in accordance with the pseudo-secondorder dynamics model, that is, the rate of degradation is controlled by the extra-particle process such as surface adsorption. Moreover, we further confirmed by high-performance liquid chromatography that the complexes are indeed a significant ability to degrade phenol.

Hydrothermal synthesis, structures, and magnetic properties of three novel 5-aminoisophthalic acid ligand bridged transition metal cation polymers

Three novel 5-aminoisophthalic acid (AIP) bridged polymers [Co(C8NH5O4)(H2O)]n (1), [Ni(C8NH5O4) (H2O)2]n (2), and [Zn(C8NH5O4)(H2O)]n (3) were synthesized by hydrothermal reactions and characterized by IR, Raman, elemental analysis, ESR, and magnetic measurements. X-ray single-crystal analyses were carried out for [Co(C8NH5O4)(H2O)]n (1), which crystallizes in the triclinic system, space group P1, with a = 6.477(1) A, b = 7.130(1) A, c = 9.826(2)A, α = 108.9(1)°, β = 93.97(3)°, γ = 98.82(3)° and Z = 2; for [Ni(C8NH5O4) (H2O)2]n (2), in the triclinic system, space group P1, a = 6.425(1) A, b = 8.115(2) A, c = 10.146(2) A, α = 113.09(3)°, β = 99.64(3)°, γ = 98.90(3)°, and Z = 2; and for [Zn(C8NH5O4)(H2O)]n (3), in the monoclinic system, space group P2(1)/n, a = 9.044(1) A, b = 8.264(1) A, c = 11.646(1) A, β = 100.77(1)°, and Z = 4. The single X-ray diffraction studies reveal that 1 consists of an infinite honeycomb layer formed by four crystallographically independent motifs packed alternatively together; 2 consists of an infinite neutral railroad-like linear polymer, and 3 consists of infinite layers of alternating four-coordinated Zn(II) cations and AIP ligands. Finally, they are all packed into beautiful three-dimensional frameworks through complicated hydrogen bonding. Antiferromagnetic and ferromagnetic behaviors were observed for 1 and 2 from the magnetic measurements.
