Five new rubidium borates, namely Na1/3Rb5/3[B4O5(OH)4] (1), Rb4[B12O18(OH)4] (2), Rb2Ba[B12O18(OH)4] (3), Rb2[B5O8(OH)] (4) and NaRb0.5[B6O10]·0.5H3O (5) have been synthesized under solvothermal conditions. Compound 1 features a 0D structure composed of [B4O5(OH)4]2− clusters. After changing the metal salt, new cyclic [B12O20(OH)4]8− clusters in 2 and 3 are formed, resulting in 1D chains. Such a chain structure is first discovered in dodecaborates. By tuning the reaction temperature and pH of the reaction media, compound 4 with a 4-connected 2D oxoboron layer constructed from partially protonated [B5O10(OH)]6− and compound 5 with a 6-connected 3D framework constructed from [B6O13]8− clusters are successfully isolated. Since compounds 1 and 4 crystallize in the non-centrosymmetric (NCS) space group, second harmonic generation (SHG) measurements and dipole moment calculations have been carried out. The SHG response of 4 is 2.0 times that of KH2PO4 (KDP), which is higher than those of related analogues.

Isolated large-spin Heisenberg antiferromagnetic uniform chain is quite rare. Here, we have successfully synthesized an ideal one-dimensional (1D) S = 5/2 linear-chain antiferromagnet [C2NH8]3[Fe(SO4)3], which crystallizes in a trigonal lattice with the space group R3c. A broad maximum at Tmax = 18 K is observed in the magnetic susceptibility curve. Notably, no long-range magnetic ordering is observed down to 2 K even if the material has a large Curie–Weiss temperature of θCW = −25.5 K. High-field magnetization at 2 K shows a linear increase until saturation at 30 T, and a high-field electron spin resonance (ESR) reveals the absence of a zero-field spin gap. The intrachain interaction J and interchain interaction J′ are determined. Quite a small ratio of J′/J < 2.5 × 10–3 suggests that [C2NH8]3[Fe(SO4)3] behaves as an ideal 1D uniform linear-chain antiferromagnet, in which the magnetic ordering is prevented by the extremely small interchain interaction and quantum fluctuation even for a classical spin of S = 5/2.

The development of new materials for the design of sensitive and responsive sensors has become a crucial research direction. Here, two silver cluster-based polymers (Ag-CBPs), including one-dimensional {[Ag22(L1)8(CF3CO2)14](CH3OH)2}n chain and two-dimensional {[Ag12(L2)2(CO2CF3)14(H2O)4(AgCO2CF3)4](HNEt3)2}n film, are designed and used to simulate the human nose, an elegant sensor to smells, to distinguish organic solvents. We study the relationship between the atomic structures of Ag-CBPs determined by x-ray diffraction and the electrical properties in the presence of organic solvents (e.g., methanol and ethanol). The ligands, cations, and the ligated solvent molecules not only play an important role in the self-assembly process of Ag-CBP materials but also determine their physiochemical properties such as the sensing functionality.

A new dysprosium complex [Dy(IA)2(H2O)4]nnNO3 (1; IA is isonicotinic acid anion), was synthesized. The structure was determined by single-crystal X-ray crystallography. Every two neighboring Dy3+ ions are interlinked by two μ2-bridging IA groups to form a one-dimensional (1-D) chain. The chains link to each other through the π···π interactions and yield a three-dimensional (3-D) supramolecular network. This complex displays yellow photoluminescence, which should be due to the 4F9/2 → 6H13/2 transition of the 4f electrons of the Dy3+ ions. The solid-state UV/Vis diffuse reflectance spectrum unveils that this compound has a wide optical band gap of 2.08 eV.

High-temperature scintillation detectors play a significant role in oil exploration. However, traditional scintillators have limited ability to meet the requirements of practical applications owing to their low thermal stability. In this study, we designed and developed a one-dimensional (1D) Cs5Cu3Cl6I2 scintillator with high thermal stability. In addition, by preparing Cs5Cu3Cl7I, we proved that the Cs5Cu3Cl6I2 scintillator exhibits high thermal stability because the bridges linking the structural units in the 1D chain structure are only formed by I– ions, which improve their structural rigidity. The scintillator has a high steady-state light yield (59,700 photons MeV–1) and exhibits the highest spatial resolution for powder-based scintillation screens (18 lp mm–1) after cyclic treatment within the temperature range of 298–423 K. The Cs5Cu3Cl6I2 scintillator allows the visualization of alloy melting, indicating that it has significant potential for application in high-temperature environments. This study provides a new perspective toward the design of scintillators with high thermal stability.

A coordination supramolecular polymer, [Cu(bipy)(SO 4 )] n , was prepared as an adsorbent. It has a molecular structure of one-dimensional chain with dense adsorption sites. Three divalent dyes including Congo red, Orange G and Reactive Brilliant red X-3B were tested as pollutants in the adsorption study. The adsorbent showed extraordinary adsorption capacity for all three dyes, reaching 2429 mg/g, 915 mg/g and 1333 mg/g for Congo red, Reactive Brilliant red X-3B and Orange G, respectively. The Langmuir isotherm model can well describe the adsorption isotherm. In kinetic study, all of the three dyes presented a model of pseudo second-order. According to the kinetic rate constants, the adsorption processes are very fast and different for three dyes. The difference can be attributed to the divalent character and the different structure of the dye’s molecule. Based on their discrepancy of adsorption velocity, separation of dyes was attempted through kinetic separation between Congo red and X-3B. A separation coefficient was developed, which can well describe the separation performance results. The results show that the two dyes can be separated quickly and efficiently by [Cu(bipy)(SO 4 )] n .

The solvent free reaction of Zn(OAc)2 with an imidazole ligand resulted in a 1-dimensional (1D) chain structure with the formula [Zn(Im)(HIm)2(OAc)] (Im = imidazolate, HIm = imidazole, OAc = carboxylate) (1). The results by kinetic experiments suggest that (1) likely evolves from an unidentified metastable phase. This new 1D chain precursor (1) is a quaternary system comprising Zn, Im, OAc and HIm. We have used this 1D compound as a single precursor to prepare 3-dimensional (3D) Zn(Im)2 frameworks. Specifically, two Zn(Im)2 frameworks with known zni and coi topologies were prepared via thermal-mediated transformation when heated in an open atmosphere and in a closed vessel, respectively. In an open atmosphere, the kinetic experiments confirmed the rapid phase transformation from (1) to zni without formation of an intermediate phase. In contrast, in the formation process of coi in a closed vessel, phase transformation from (1) to zni and immediately from zni to coi was observed. Thus, in a closed vessel, the released molecules, HOAc and HIm, were occluded in the framework, which may together exert a cooperative structure-directing effect on the formation of the coi framework. Thus, a single precursor approach was established for the synthesis of ZIFs. The present work represents the first example of transforming a 1D coordination polymer into 3D ZIF framework structures.

Luminescent Cu(I) complexes have drawn considerable attention as alternative materials to precious transition metal complexes due to their low cost and electron configuration. Discrete heteroleptic diamine-diphosphine copper(I) complexes have been investigated owing to their outstanding photophysical features. However, heteroleptic copper(I) coordination polymers remain mostly unexplored. Herein, we report the synthesis and photophysical characterization of a heteroleptic copper(I) coordination polymer by employing bidentate oxybis(2,1-phenylene)bis(diphenylphosphine) (POP) diphosphine and nitrogen heterocyclic 5-[4-(1-imidazolyl)phenyl]-2H-tetrazole (ipt) as ligands. By utilizing the mixed-solvent strategy, a one-dimensional (1D) linear chain was constructed under solvothermal reaction conditions. Temperature-dependent emission spectra combined with decay time measurements demonstrate that emission originated from triplet phosphorescence at ambient temperature.

Cesium copper halide perovskite-like nanocrystals (NCs) have emerged recently due to their nontoxicity and highly efficient and peculiar optoelectronic properties; however, this field is far from being quested yet. In this study, Cs5Cu3Cl6I2 NCs in a one-dimensional chain structure are proposed by a modified hot injection method for the first time. The as-synthesized highly even Cs5Cu3Cl6I2 NCs yield a blue emission at 464 nm, coupling a high photoluminescence quantum yield (PLQY) of 73.7%. The large Stokes shift of 186 nm and broadband emission demonstrate the existence of self-trapped excitons in Cs5Cu3Cl6I2 NCs under UV excitation. Unlike the zero-dimensional prototype, one-dimensional chains consist of different polyhedron connection fashions, fostering their unique luminescent properties. We found Cs5Cu3Cl6I2 NCs possess an asymmetric PL emission peak prevailing in a broad temperature range, highly correlating to abnormal multiple self-trapped excitons at 2.95 eV, 2.69 eV, and 2.53 eV, respectively. Interrogating the fundamental, triple Cu–Cu interactions originating from various polyhedral connection ways of one-dimensional chains are responsible for the hybrid excitonic states. This work establishes a rising class of lead-free NCs as an eligible candidate for stable functional device application and illustrates the fundamentals underlying the dissimilar excitonic properties of one-dimensional copper halides.

A new rare-earth borate Na3YB8O15 was fabricated by the flux method. The compound crystallizes in the P group, and shows a three-dimensional network built by [B8O17] fundamental building blocks (FBBs) with [NaO6], [NaO7], and [YO7] polyhedra. The [B8O17] FBBs are composed of five planar BO3 and three BO4 tetrahedra and connected via corner-sharing to construct a unique one-dimensional (1D) [B8O15]∞ infinity chain that is observed for the first time in the Na2O–Y2O3–B2O3 system compound, enriching the structural diversity of rare-earth borate. The title compound exhibits a short ultraviolet (UV) cutoff edge of ∼195 nm and a wide experimental band gap of 5.50 eV. DFT calculations indicate that Na3YB8O15 is a direct band gap compound with a calculated GGA band gap of 5.14 eV, and the band gap is mainly determined by B 2p and O 2p orbitals. The results update the phase diagram of Na2O–Y2O3–B2O3 and enrich the diversity of rare-earth metal borates.

Oxychalcogenides have gained widespread attention as promising infrared nonlinear optical (IR-NLO) candidates. However, high-performance oxychalcogenides have rarely been reported in the ultraviolet (UV) region owing to the low energy gaps (Eg < 4.0 eV). Herein, two non-centrosymmetric (NCS) oxychalcogenides with one-dimensional (1D) chain structures and wide Eg (>4.3 eV), namely, AEGeOS2 (AE = Sr and Ba), have been discovered by combined experiments and theory calculations as a new source of UV-NLO materials. Significantly, they exhibit excellent comprehensive performance comparable to the commercial UV-NLO material KH2PO4 (KDP), including large phase-matching ranges (>380 nm), sufficient second harmonic generation intensities (0.7–1.1 × KDP), high laser-induced damage thresholds (1.2 × KDP), wide transparent regions (0.26–12.2 μm), and good thermal stability (up to 1100 K). Moreover, systematic structure–activity relationship analysis illustrates that the 1D homochiral helical [GeOS2]2– chains composed of heteroanionic [GeS2O2] units make major contribution to the desirable UV-NLO performance. This work makes the two compounds shine out as new energy in the UV-NLO field and offers a new perspective for the exploration of structure-driven functional oxychalcogenides.
