A Zeolitic Organo−Metallophosphate Hybrid Material with Bimodal Porosity

Abstract

The first metal carboxylatophosphate, NTHU-2, contains inorganic ZnHPO4 layers linked by BDC units (BDC = 1,4-benzene dicarboxylate or terephthalic anion); the three-dimensional anionic framework has large pores with the smallest diameter being 1.36 nm; N2 sorption isotherms reveal both micro- and mesoporosity; the new material is photoluminescent and disassembles in water wherein the discharged organic fragments form mixed crystals.

Variant Luminescence from an Organic–Inorganic Hybrid Structure with an Isolated 4‐Ring Zinc Phosphate Tecton

“…The residue, confirmed to contain only the inorganic material from NTHU-10, also gave a weak blue emission line at 470 nm ( Figure S2a in the Supporting Information), a blue shift by 15 nm as compared with that of 10 d. The result indicated that the emission peak observed at 485 nm for NTHU-10 should originate from the inorganic [Zn 2 -(H 2 PO 4 ) 2 ] 2+ unit. Next, the emission peak at 515 nm was [15] 1D chains in NTHU-8, [14] and 0D clusters in NTHU- 10. considered to be attributed to ligand-to-metal charge transfer LMCT from O btec À Zn bonds which, as in MOF structures, are often observed in the region from 500 to 530 nm. [4,20] Meanwhile, we prepared a solid sample of K 4 (btec) [21] to measure the ligand-based emission of btec 4À .…”

“…Discovery of NTHU-10 marks completion of a hybrid framework system that contains all three possible dimensionalities of inorganic tectons ( Figure 3). [14,15] The four optical analogues 10 a, 10 b, 10 c and 10 d were found to share the common structure of NTHU-10. [16] The unique structure contains discrete 4-ring clusters of [Zn 2 -(H 2 PO 4 ) 2 ] 2+ as the 0D inorganic substructure, which are interlinked by four-connected btec 4À ligands into a hybrid [Zn 2 (H 2 PO 4 ) 2 (btec)] 2À layer.…”

Organic template-directed indium phosphite-oxalate hybrid material: Synthesis and characterization of a novel 3D |C6H14N2|[In2(HPO3)3(C2O4)] compound with intersecting channels

“…Recently, the oxalate unit cross-link the inorganic parts and act as a bridge in the phosphate-oxalates giving rise to a new family of inorganic/organic hybrid materials [14][15][16]. Large numbers of template-directed metal phosphate-oxalates have recently been prepared and characterized [17][18][19][20].…”

“…Wang and co-workers successfully synthesized two organic template-directed indium phosphite compounds |C 2 N 2 H 10 |[In(OH) 3 (HPO 3 )] [10] and |C 4 N 2 H 12 |[In 2 -(HPO 3 ) 3 (H 2 PO 3 ) 2 ] [11]. Subsequently, two indium phosphite compounds were reported by Liu et al [12,13].Recently, the oxalate unit cross-link the inorganic parts and act as a bridge in the phosphate-oxalates giving rise to a new family of inorganic/organic hybrid materials [14][15][16].

A Fully Integrated Nanotubular Yellow‐Green Phosphor from an Environmentally Friendly Eutectic Solvent

“…[9][10] While major attention has been focused on pore-size-related absorption properties, we have concurrently discovered extraordinary photoluminescence (PL) properties in openframework metal phosphates. [11][12][13][14][15][16] We discovered two metal phosphates, NTHU-4 [12] and NTHU-6, [13] which have novel nanoporous structures. These metal phosphates, unlike commercialized or developed color-conversion phosphors with emissions that originate from emitting activators doped into condensed host lattices, [17] contained no metal activators or any form of chromophores, but could emit intense yellow light under the excitation of near-ultraviolet (NUV) and blue light.…”
