This study proposes a synthetic strategy for constructing 1D-COFs and investigates the mechanism of improved fluorescence performance. By introducing non-covalent interactions, non-radiative transitions can be weakened, thus enhancing the fluorescence intensity of 1D-COFs.
Covalent organic frameworks (COFs) have been extensively investigated due to their unique structure, porosity, and functionality. However, at the topological level, COFs remain as two-dimensional (2D) or three-dimensional (3D) structures, while COFs with one-dimensional (1D) topology have not been systematically explored. In this work, we proposed a synthetic strategy for the construction of 1D-COFs based on non-linear edges and suitable high-symmetry vertices. Compared with their 2D-COFs counterparts, the 1D-COFs with AIEgens located at the vertex of the frame exhibited enhanced fluorescence. The density functional theory (DFT) calculations revealed that the dimensional-induced rotation restriction (DIRR) effect could spontaneously introduce additional non-covalent interactions between the strip frames, which could substantially diminish non-radiative transitions. This work also provides protocols for the design of 1D-COFs and a guidance scheme for the synthesis of emitting COFs.

A belief rule-base approach to the assessment and improvement of seismic resilience of high-speed railway station buildings

Yumeng Tang, Shuang Li, Changhai Zhai

Summary: As an integral part of the railway system, railway stations play a crucial role in ensuring convenient passenger transfer and efficient mass transportation. However, assessing the resilience of high-speed railway stations has been a challenge due to the complex nature of their components, spatial structure, and engineering facilities. This study proposes a method to assess and improve the seismic resilience of high-speed railway stations through the use of subsystems analysis and hierarchical belief rule-base (BRB) optimization.

Pressure Engineering Toward Harvesting the Bright Deep-Blue-Light Emission in Y-based Metal-Organic Frameworks

Yixuan Wang, Chuang Liu, Xue Yong, Xinyi Yang, Jingkun Yu, Siyu Lu, Fuquan Bai, Shiping Wang, Kai Wang, Zhaodong Liu, Bingtao Feng, Xuyuan Hou, Hao Liu, Banglin Chen, Qianrong Fang, Bo Zou

Summary: The emergence of metal-organic frameworks (MOFs) has provided a new platform for low-cost and color-saturated blue light-emitting diodes, which are ideal for display and solid-state lighting applications. However, many established MOFs still exhibit weak deep-blue-light emission due to low energy/charge transfer efficiency. This research reports a pressure-treated strategy to greatly enhance the photoluminescence performance of deep-blue light-emitting Y(BTC)(H2O)(6) and provides insights into the structure-property relationship in MOFs, offering a promising strategy for developing deep-blue-emitting MOFs materials.

A Microporous Metal-Organic Framework with Unique Aromatic Pore Surfaces for High Performance C2H6/C2H4 Separation

Yingxiang Ye, Yi Xie, Yanshu Shi, Lingshan Gong, Joshua Phipps, Abdullah M. Al-Enizi, Ayman Nafady, Banglin Chen, Shengqian Ma

Summary: Developing adsorptive separation processes using C2H6-selective sorbents is a promising alternative for energy-intensive cryogenic distillation in C2H4 purification. Our study showed that Ni-MOF 2 exhibited significantly higher performance in C2H6/C2H4 separation compared to Ni-MOF-1. The unique aromatic pore surfaces and suitable pore spaces of Ni-MOF 2 contribute to its high C2H6 uptake capacity, making it one of the best porous materials for this gas separation. It can generate 12 L kg(-1) of polymer-grade C2H4 product from equimolar C2H6/C2H4 mixtures at ambient conditions.

Two high-order energy-preserving and symmetric Gauss collocation integrators for solving the hyperbolic Hamiltonian systems?

Changying Liu, Jiayin Li, Zhenqi Yang, Yumeng Tang, Kai Liu

Summary: In this paper, an energy-preserving collocation integrator is derived for solving hyperbolic Hamiltonian systems. Two specific high-order energy-preserving and symmetric integrators are presented by choosing collocation nodes as two and three Gauss-Legendre points, respectively. The convergence and symmetry of the constructed energy-preserving integrators are rigorously analyzed. Numerical results confirm the energy conservation property and accuracy of the proposed integrators.

Ratiometric fluorescent sensor for sensitive detection of 3-methoxytyramine based on hydrogen-bonded organic framework

Faqiang Chen, Hui Xu, Youlie Cai, Penglei Shen, Wenhua Zhang, Thamraa Alshahrani, Gongxun Bai, Shiqing Xu, Banglin Chen, Junkuo Gao

Summary: In this study, we demonstrate the first use of a microporous HOF material HOF-BTB with high specific surface area for ratiometric fluorescent detection of the tumor biomarker 3-methoxytyramine (3-MT) in pheochromocytomas and paragangliomas. HOF-BTB exhibits rapid, highly accurate, and sensitive detection of 3-MT, with a detection limit as low as 46 nM. To the best of our knowledge, this HOF material achieves the best detection limit value among luminescent sensors and is comparable to high-performance liquid chromatography or liquid chromatography-tandem mass spectrometry.

Summary: This study reports a novel linkage conversion strategy for the preparation of crystalline thiadiazole-linked covalent organic frameworks (COFs) with excellent stability. The prepared COFs maintain both porosity and crystallinity, while enhancing chemical stability. Compared to N-acylhydrazone-linked COFs, thiadiazole-linked COFs are more favorable for lowering exciton binding energy and promoting π-electron delocalization.
