摘要

A new class of organoboron compounds containing a boryl and an amino group at the o,o'-positions of biphenyls display bright through-space intramolecular charge transfer fluorescence owing to the close contact between the boryl and the amino groups. Binding of the fluoride ions results in the remarkable blue shift and color change of the fluorescence, enabling colorimetric and ratiometric fluoride ion sensing.

Mechanism of Ir-Mediated Selective Pyridine o-C-H Activation: The Role of Lewis Acidic Boryl Group

Jiahao Liu, Yinwu Li, Jingxing Jiang, Yan Liu, Zhuofeng Ke

Summary: The study systematically provided mechanistic scenarios including boryl-directed (BD) oxidative addition, nondirected (nonBD) oxidative addition, and boryl-metal cooperation via B-hydrido type (BHMC) or B-carbanion type (BCMC) mechanisms to elucidate the role of a Lewis acidic boryl group in selective o-C-H activation of pyridine with PBP-Ir complexes. The results suggest the plausibility of BD and BCMC mechanisms, while nonBD and BHMC mechanisms are less preferred due to weak interactions and large distortions. Various PBP-Ir complexes have been evaluated to further explore the guidelines of this mechanistic understanding for the rational design of Lewis acid-transition-metal catalysts.

Reduction of transient histidine radicals by tryptophan: influence of the amino group charge

Olga B. Morozova, Alexandra V. Yurkovskaya

Summary: The second-order rate constants of histidine radicals reduced by tryptophan were obtained for different combinations of amino acids and their N-acetyl derivatives. Contributions from inter- and intramolecular reduction were revealed for the dipeptide N-acetyl histidine-tryptophan. The pH dependences of the rate constants were determined by the protonation state of tryptophan's amino group, suggesting a possible reaction mechanism of proton coupled electron transfer.

C & BULL;& BULL;& BULL;O and Si & BULL;& BULL;& BULL;O Tetrel Bonds: Substituent Effects and Transfer of the SiF3 Group

Zhihao Niu, Qiaozhuo Wu, Qingzhong Li, Steve Scheiner

Summary: The tetrel bond between 1,2-benzisothiazol-3-one-2-TF3-1,1-dioxide (T = C, Si) and pyridine-1-oxide (PO) and its derivatives (PO-X, X = H, NO2, CN, F, CH3, OH, OCH3, NH2, and Li) was investigated using quantum chemical methods. The Si-O tetrel bond is strong, with interaction energies reaching a maximum of nearly 70 kcal/mol, while the C-O tetrel bond is weaker, with interaction energies between 2.0 and 2.6 kcal/mol. The presence of an electron-withdrawing substituent weakens the tetrel bond, while an electron-donating group strengthens it. The SiF3 group transfers approximately halfway between the acid's nitrogen and the base's oxygen without the assistance of cooperative effects from a third entity.

Highly efficient blue light-emitting polymer containing a Benzo[b]naphtho [1,2-d]thiophene -S,S-dioxide unit

Jin Xu, Yuhao Zhang, Ke Du, Wei Yang

Summary: A benzo[b] naphtho[1,2-d]thiophene-S,S-dioxide (NSO) electron-deficient acceptor was synthesized to lower the electron-withdrawing ability. The copolymers PPF-NSs and PPF-NSOs were studied, and it was found that intermolecular energy transfer was the main mechanism of photoluminescence for PPF-NSs, while intramolecular charge transfer played the main role for PPF-NSOs. PPF-NSOs showed superior blue emission at a low acceptor concentration, while the energy transfer-based copolymer PPF-NS1 also achieved satisfactory performance.

Neighboring Group Effects on the Rates of Cleavage of Si-O-Si-Containing Compounds

Ethan A. Gormong, Dorian S. Sneddon, Theresa M. Reineke, Thomas R. Hoye

Summary: The presence of a nearby tethered functional group significantly affects the cleavage rate of an Si-O bond. In this study, we investigated the relative rates of cleavage of model substrates with different Si-O substructures using in situ H-1 NMR spectroscopy. The computed trends in the relative rates correlated well with the experimental data. Additionally, we observed a siloxy-metathesis reaction facilitated by a pendant dimethylamino group.

Carbazole-Containing Polymer-Assisted Trap Passivation and Hole-Injection Promotion for Efficient and Stable CsCu2I3-Based Yellow LEDs

Zhuangzhuang Ma, Xinzhen Ji, Meng Wang, Fei Zhang, Zibin Liu, Dongwen Yang, Mochen Jia, Xu Chen, Di Wu, Yu Zhang, Xinjian Li, Zhifeng Shi, Chongxin Shan

Summary: Perovskite light-emitting diodes (LEDs) are promising light sources for future lighting and display technologies. However, achieving yellow electroluminescence, environmental stability, and lead toxicity are challenges. By incorporating a hole-transporting polymer into the CsCu2I3 emitter, the electroluminescent performance of the LEDs is improved, resulting in significantly enhanced device performances. The external quantum efficiency of the yellow LEDs is increased by 8.5 times, and the half-lifetime reaches 14.6 hours, making them the most stable yellow LEDs based on perovskite systems reported so far.

Conductance of o-carborane-based wires with different substitution patterns

Shi-Nuo Xu, Yan Zheng, Jing-Yao Ye, Zhong-Yang Chen, Jian-Feng Yan, Yan-Hou Geng, Wenjing Hong, Yao-Feng Yuan

Summary: Here, we present the synthesis, structure, and single-molecule conductance of three o-carborane-based molecular wires with multiple conduction channels. Through experimental and theoretical studies, we found that o-carborane-based wires have a unique three-dimensional structure that facilitates through-space transmission paths and stable molecular junction formation compared to phenyl-centered wires. The significant difference in conductance is attributed to the combination of multiple conduction channels and quantum interference. Understanding the impact of different bridging groups and anchor group substitution patterns provides valuable insights for designing multichannel molecular wires based on o-carboranes.

Swapping the Positions in a Cross-Strand Lateral Ion-Pairing Interaction between Ammonium- and Carboxylate-Containing Residues in a β-Hairpin

Cheng-Hsin Huang, Tong Wai Wong, Chen-Hsu Yu, Jing-Yuan Chang, Shing-Jong Huang, Shou-Ling Huang, Richard P. Cheng

Summary: This study demonstrates the importance of cross-strand lateral ion-pairing interactions for antiparallel beta-sheet stability, with the swapping of charged residues positions not significantly affecting interaction dynamics. Most swapped peptides showed higher folding populations, indicating the significance of lateral ion-pairing interactions in protein structures.

Method for highly selective, ultrasensitive fluorimetric detection of Cu2+and Al3+by Schiff bases containing o-phenylenediamine and o-aminophenol

Shivani Sharma, Joy Debnath, Kalyan Sundar Ghosh

Summary: Schiff base probes 1 and 2 were developed as highly selective fluorimetric chemosensors for Cu2+ and Al3+ ions respectively. The fluorescence emission of probe 1 at 415 nm was quenched by Cu2+, while the weak fluorescence of probe 2 at 506 nm was specifically enhanced by Al3+. The metal ion-probe complexation stoichiometry was found to be 1:1. The probes showed low detection limits of 9.9 and 2.5 nM for Cu2+ and Al3+ respectively. The sensing mechanisms were proposed based on density functional theory and spectroscopic results. Probe 1 was also used in a logic gate for Cu2+ detection, and both probes were applied for quantitative estimation of Cu2+ and Al3+ in water samples.

Unique interfacial adsorption behavior of a hydroxy group-containing amino acid surfactant

Shiho Yada, Miyako Wakizaka, Hiroshi Shimosegawa, Hiroya Fujita, Munehiro Yamada, Yukako Matsue, Tomokazu Yoshimura

Summary: The interfacial adsorption properties of a novel hydroxy-group-containing amino-acid-type surfactant and a conventional hydroxy-group-free amino-acid-type surfactant were investigated in an alkaline solution. The novel surfactant showed a lower critical micelle concentration and nonionic-like behavior due to hydrogen bonding between hydroxy groups and carboxylate ions, which reduced electrostatic repulsion between hydrophilic groups.

Thiourea- and Amino-Substituted Benzoxadiazole Dyes with Large Stokes Shifts as Red-Emitting Probe Monomers for Imprinted Polymer Layers Targeting Carboxylate-Containing Antibiotics

Virginia Valderrey, Kornelia Gawlitza, Knut Rurack

Summary: Bifunctional fluorescent molecular oxoanion probes based on the benzoxadiazole (BD) chromophore are developed in this study. These probes integrate a thiourea binding motif and a polymerizable 2-aminoethyl methacrylate unit in the core, and exhibit strongly Stokes shifted absorption and fluorescence due to concerted charge transfer. By binding electron-rich carboxylate guests, the emission of the probes further red-shifts, allowing for detection of antibiotics in highly polar solvents.
