摘要

Two 3-D and one 2-D metal-organic frameworks [Cu8I8(L-1)(4)](n) (1), [Cu8I8(L-2)(4)](n) (2) and [Cu4I4(L-3)(2)](n) ( 3) were synthesized using three novel pyridine and pyrazole supported 1,2,3-triazoles, 1-(4-picolyl)-4-butyl-1H-1,2,3-triazole (L1), 1-(4-picolyl)-4-pentyl-1H-1,2,3-triazole( L2) and 1-(4-picolyl)-4-(3,5-dimethylpyrazolylmethyl)-1H-1,2,3-triazole (L3). In both complexes 1 and 2, there co-exist a 1-D Cu(I) oligomer and Cu-4 tetrahedron cluster in the 3-D polymeric structures. Complex 3 shows a 2-D (4, 4) net with the stair-step Cu4I4 as node and L3 as a building block. All three complexes exhibit photoluminescence.

NH-1,2,3-triazoles as versatile building blocks in denitrogenative transformations

Vladimir Motornov, Petr Beier

Summary: This review focuses on the utilization of NH-1,2,3-triazoles as easily accessible building blocks for denitrogenative ring cleavage transformations, providing multifunctionalized nitrogen heterocycles and N-alkenyl compounds. These processes offer a convenient route to a range of pharmaceutically relevant heterocyclic cores and N-alkenyl compounds by leveraging the ready availability of NH-1,2,3-triazoles. The synthetic usefulness of in situ acylated NH-1,2,3-triazoles as viable alternatives to widely explored N-sulfonyl-1,2,3-triazoles in ring cleavage processes is highlighted.

Synthesis and Characterizations of Polythiophene Networks with Nonplanar BN Lewis Pair Building Blocks

Xue Han, Cece Xue, Zhuo Zhao, Min Peng, Qing Wang, Haiming Liu, Na Yu, Chaodan Pu, Yi Ren

Summary: Doping boron into organic π-conjugated polymers endows them with interesting optoelectronic properties. In this study, a new series of thienylborane-pyridine Lewis pairs were synthesized via reactions between thienylborane and various pyridine derivatives. The Lewis pairs were then cross-linked with distannylated thiophene to form BN-cross-linked polythiophenes. The resulting polymers showed highly uniform chemical structures and good stability, and the presence of topological BN structures enhanced their intramolecular charge separation. As a proof-of-concept, a representative BN-cross-linked polythiophene was tested as a catalyst for photocatalytic hydrogen evolution.

Differentiation between Isomeric 4,5-Functionalized 1,2,3-Thiadiazoles and 1,2,3-Triazoles by ESI-HRMS and IR Ion Spectroscopy

Dmitrii M. M. Mazur, Elettra L. L. Piacentino, Giel Berden, Jos. Oomens, Victor Ryzhov, Vasiliy A. A. Bakulev, Albert T. T. Lebedev

Summary: A large variety of 1,2,3-thiadiazoles and 1,2,3-triazoles are widely used in organic chemistry as important building blocks. Mass spectrometry, specifically electrospray ionization (ESI) with ion detection, is an effective analytical tool for studying the structures of these compounds. Gas-phase rearrangement of 1,2,3-triazoles into 1,2,3-thiadiazoles was observed under certain conditions. Infrared multiple photon dissociation (IRMPD) spectroscopy helped identify important fragment ions. However, further evidence is needed to confirm the solution-phase transformation of thiadiazoles into triazoles.

Dogyun Kim, Jeong Min Lee, Jeongeun Song, Seul Woo Lee, Hong Geun Lee, Kyoung Taek Kim

Summary: Polyesters with protein-like structural complexity have the potential to be used as biomaterials and polymeric materials. By synthesizing enantiomeric omega-hydroxy acids (OHAs) with defined atomic composition, stereochemical configuration, and substituent chemistry, we can build discrete and sequence-defined polyesters, allowing the incorporation of various functional groups at specific locations. Our results demonstrate the possibility of engineering polyesters with structural sophistication comparable to biopolymers like proteins and nucleic acids.

Boronate Building Blocks for Intracellular Protein Delivery

Qianyi Ren, Yiyun Cheng, Jia Lv

Summary: Intracellular protein delivery is crucial for biotherapeutics and biotechnologies but faces challenges in terms of protein binding, cellular uptake, endosomal escape, and protein release. Boronate building blocks have shown promise in overcoming these limitations due to their versatile reactivities and stimuli-responsive property. Boronate ligands transport proteins into the cytosol via receptor-mediated endocytosis and can also enhance binding to native proteins on nanocarriers.

Barriers and enablers to influenza vaccination uptake in adults with chronic respiratory conditions: applying the behaviour change wheel to specify multi-levelled tailored intervention content

Allyson J. Gallant, Paul Flowers, Karen Deakin, Nicola Cogan, Susan Rasmussen, David Young, Lynn Williams

Summary: This study aimed to enhance influenza vaccination uptake among adults with chronic respiratory conditions by using the Behaviour Change Wheel (BCW) to specify intervention content. The study identified barriers and enablers to vaccination through focus groups, interviews, and surveys. Factors such as perceptions of vaccine side effects, time constraints, and fear of needles were found to be common barriers, while enablers included protection from influenza, reminders, and support from others. Based on the findings, the study proposed a suite of multi-level intervention components involving diverse actors, recipients, and settings to enhance vaccination uptake.

Summary: In this study, nanoscale two-dimensional Fe-II- and Co-II-based metal-organic frameworks (NMOFs) were shown to have an anticancer effect in the tumor microenvironment. These NMOFs can catalyze the production of hydroxyl radicals (center dot OH) and O-2 in the presence of H2O2, and consume O-2 to produce singlet oxygen (O-1(2)) through photodynamic therapy. Both center dot OH and O-1(2) are reactive oxygen species (ROS) that inhibit cancer cell proliferation.

Summary: Coordination polymers of transition metal ions, such as silver(I), are important in coordination chemistry. Silver(I) coordination polymers are often insoluble in common solvents, making it difficult to analyze them in solution. However, by using a tetramethyl-substituted bipyrazole ligand, we have synthesized more soluble silver(I) complexes with coordinated ions CF3CO2- and CF3SO3-. We determined the structures of these complexes and studied their solution behavior using various spectroscopic techniques.

The reaction could be performed under compact fluorescent lamp light or sunlight and was tolerant of various functional groups. It was successfully applied to the synthesis of natural products and drug molecules, even at a gram-scale. The mechanism involves several steps including oxidative addition, transmetalation, energy transfer, and reductive elimination.
