Abstract ：
A novel multi-site receptor 1 bearing four ferrocenyl arms comprising benzimidazolium moieties was synthesized and structurally characterized by IR, NMR, elemental analysis, mass spectra. Moreover, the structure of receptor 1 was confirmed by X-ray crystallography, it was clear that the cationic heterocyclic was interacted with PF6− through C–H···F hydrogen bonds. Its electrochemical properties of sensing the various anions were investigated by cyclic voltammograms (CV) and differential pulse voltammetry (DPV), the receptor 1 displayed a significant cathodic shift for F−and OH−. The addition of F− and OH−to the solution of receptor 1 resulted in obvious absorption changes in the UV–Vis spectrum, showing that receptor 1 was an excellent sensor for these analytes (F−: LOD = 3.11 × 10−6 M, LOQ = 1.03 × 10−5 M, Ka = 5.83 × 105 M−1; and OH–: LOD = 1.36 × 10−6 M, LOQ = 4.11 × 10−5 M, Ka = 9.03 × 105 M−1). 1H NMR titrations demonstrated that anion was recognized by receptor 1 through (C–H)+···X− and C–H···X hydrogen bonds, the binding process involve initial formation of hydrogen bond and followed by deprotonation. © 2024

Abstract ：
Polyferrocene macrocycles hold immense potential in the fields of molecular electronics and electrochemistry, primarily due to their multiple metal centers. However, developing highly efficient synthetic strategies for constructing these rings remains a significant challenge. In this study, we successfully synthesized triferrocenyl macrocycles using Pt-mediated coupling strategy and determined their configuration using single-crystal X-ray diffraction analysis, revealing a structure reminiscent of the Penrose Stair. We comprehensively investigated the macrocycle’s structure, photophysical properties, and employed density functional theory (DFT) calculations to gain further insights. Notably, this macrocycle exhibits several advantageous features, including a flexible structure, good solubility, and a highly efficient synthetic pathway.

Abstract ：
This study presents the design, synthesis, and comprehensive characterization of a novel series of D-π-A type malononitrile-derived chromophores, BTC-1–BTC-4. Combining various spectroscopic techniques, nonlinear Z-scan measurements, and quantum chemical calculations, we revealed the intricate relationship between nonlinear optical properties and the interplay of molecular structure, intramolecular charge transfer (ICT), and dipole moments (μ). Our experimental and computational findings corroborate that the polarization degree in the ground state, the charge separation in the excited state and twisted intramolecular charge transfer (TICT) collectively dictate the nonlinear optical properties of the compounds. Notably, BTC-1 exhibits an exceptional nonlinear absorption coefficient β value (2×10−8 m W−1), attributed to its optimized charge transfer efficiency and pronounced degree of charge separation. Our findings provide actionable insights for the rational design of high-performance organic Nonlinear optics (NLO) materials with potential applications in advanced photonic devices. © 2024 Wiley-VCH GmbH.

Abstract ：
Treatment response and prognosis estimation in advanced pulmonary adenocarcinoma are challenged by the significant heterogeneity of the disease. The current Response Evaluation Criteria in Solid Tumors (RECIST) criteria, despite providing a basis for solid tumor response evaluation, do not fully encompass this heterogeneity. To better represent these nuances, we introduce the intertumoral heterogeneity response score (THRscore), a measure built upon and expanding the RECIST criteria. This retrospective study included patients with 3-10 measurable advanced lung adenocarcinoma lesions who underwent first-line chemotherapy or targeted therapy. The THRscore, derived from the coefficient of variation in size for each measurable tumor before and 4-6 weeks posttreatment, unveiled a correlation with patient outcomes. Specifically, a high THRscore was associated with shorter progression-free survival, lower tumor response rate, and a higher tumor mutation burden. These associations were further validated in an external cohort, confirming THRscore's effectiveness in stratifying patients based on progression risk and treatment response, and enhancing the utility of RECIST in capturing complex tumor behaviors in lung adenocarcinoma. These findings affirm the promise of THRscore as an enhanced tool for tumor response assessment in advanced lung adenocarcinoma, extending the RECIST criteria's utility. In the clinical management of advanced pulmonary adenocarcinoma, a commonly observed phenomenon is the intertumoral heterogeneous response (THR), which refers to the significant variation in treatment responses among different tumors within the same patient. We introduce the intertumoral heterogeneity response score (THRscore), a measure built upon and expanding the RECIST criteria, to evaluate THR effectively, stratifying patients by progression risk. image

Abstract ：
Here, α- or β-thiophene-substituted derivatives bridged by an o-carborane group were synthesized. Scanning tunneling microscope break junction techniques have revealed that the thiophene anchoring groups form a single-molecule junction with an Au electrode. Flicker noise analysis suggests the existence of through-space transmission pathways between the thiophene units. Furthermore, the electronic coupling of the β-thiophene substituted molecule with the electrode is found to be more stable, resulting in a 70 % increase in conductance compared to the α-isomer counterpart.These findings offer valuable insights for the design and development of o-carborane-based molecules, underscoring the significance of molecular backbones and substitution patterns on their electrical transport properties. © 2024
