New 3 D Tubular Porous Structure of an Organic–Zincophosphite Framework with Interesting Gas Adsorption and Luminescence Properties

Abstract

A new 3D tubular zinc phosphite, Zn (C H N ) (HPO ) ⋅H O (1), incorporating a tetradentate organic ligand was synthesized under hydro(solvo)thermal conditions and structurally characterized by single-crystal X-ray diffraction. Compound 1 is the first example of inorganic zincophosphite chains being interlinked through 1,2,4,5-tetrakis(imidazol-1-ylmethyl)benzene to form a tubular porous framework with unusual organic-inorganic hybrid channels. The thermal and chemical stabilities, high capacity for CO adsorption compared to that for N adsorption, and interesting optical properties of LED devices fabricated using this compound were also studied.

Genuine Pores in a Stable Zinc Phosphite for High H2 Adsorption and CO2 Capture

“…For example, nanoribbon‐structured zinc phosphites exhibited white‐light emission; a bimetal phosphite with a 26‐MR channel was built of two types of helical inorganic chains; we recently reported zinc phosphites with interesting structures and properties (such as adsorption for dyes and lanthanide ions; selective removal and turn‐on detection for mercury cations). In the comparison with the previous reports of metal phosphites, [1j,7,9] the title compound displayed the uncommon structural features and genuine pores that showed good adsorption capacity for H 2 O, CO 2 , CO, CH 4 , N 2 , and H 2 (the highest H 2 capture among metal phosphites and phosphates) and the selectivity of CO 2 over CO, N 2 , and H 2 at 298 K. The synthesis, structural feature, gas adsorption, selectivity, and possible adsorption sites in NTOU ‐ 9 are discussed.…”

“…Those compounds displayed their framework openings from 40‐, 48‐, 56‐, 64‐, to 72‐MR, which overwhelmed the records of other zeolite‐related materials, such as silicate [1b,5] and germanate [6] for 18‐ and 48‐MR, respectively. For structural features, the phosphite building unit of HPO 3 may reduce connectivity between metal and itself, increasing the opportunity for the formation of more open and interrupted structures [1j,7] . Until now, crystalline materials of zeolite‐related compounds with genuine or/and large‐pore structures are limited.…”

Stable Crystalline Organic–Inorganic Hybrid Indium Phosphate with Dye Removal and Ractopamine Detection Applications

“…The TIMB molecules cross-link to the In atoms of the adjacent inorganic layers to achieve a structure where TIMB linkers are across the 12-membered rings along the bc plane (Figure b). Only a few examples of metal phosphite/phosphate materials incorporating tetradentate N-donor ligands have been reported: one zinc phosphate displayed a 2D structure in the presence of an organic molecule that acts as both a bridging linker and a bidentate bridging ligand, and two zinc phosphites exhibited interesting 3D frameworks with either tubular channels or rectangular opening windows occupied by carboxylate molecules . In this work, TIMB molecules are bonded to In atoms of the metallophosphate layers to generate a new organic–inorganic hybrid compound.…”

Two new inorganic–organic hybrid zinc phosphites and their derived ZnO/ZnS heterostructure for efficient photocatalytic hydrogen production

“…Inorganic-organic hybrid materials as a kind of functional porous material are one of the research hotpots in materials chemistry, not only because of their precise and intriguing structures but also for their potential applications in the elds of chemical separation, gas storage, catalysis, and uorescent materials. [1][2][3][4][5][6] To date, the employment of different structuredirecting or auxiliary N-donor ligands, has been recognized as an efficient strategy to fabricate new inorganic-organic hybrid materials with novel structures. [7][8][9][10][11][12][13] Among the N-donor ligands, the bis(imidazole) ligand can adopt subtly different conformations to meet the different geometrical requirements of complexes in the synthesis process (such as metal ions, molar ratios, pH value, temperature and time, etc.)…”

“…[18][19][20][21] Such as, Wang's group reported a 3D tubular porous structure of an organic-zincphosphite through 1,2,4,5-tetrakis(imidazol-1-ylmethyl) benzene, which exhibits high capacity for CO 2 adsorption and interesting optical properties of LED devices. 2 Meanwhile, utilizing 1,3,5-tris(1-imidazolyl)benzene, Wang et al prepared a serials of inorganic-organic hybrid zinc phosphites framework, which presents excellent phosphorescence property. 13 Very recently, by introducing bis(imidazole) ligand into Znphosphate system, we reported two inorganic-organic hybrid zinc phosphate frameworks for photocatalytic hydrogen evolution application.…”
