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 tri-ferrocenyl 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-pi-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 (mu). 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 beta value (2x10(-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.

Abstract ：
The synthesis, structure, and size-dependent properties of ferrocene-embedded conjugated macrocycles are described. The one-pot, two-component "shotgun" synthesis greatly expands the structural diversity and functionality of nanohoops. These eta 5-type coordination metal-nanohoops exhibit intriguing properties, including reversible redox behavior and collisional quenching with fullerenes. Notably, the addition of oxidants enhances their fluorescence intensity, while fullerenes quench it. Detailed theoretical and experimental studies reveal that fine-tuning the nanohoop size significantly influences not only the molecular conformation but also its electronic structure and photophysical properties. Ferrocene-based conjugated macrocycles were efficiently synthesized by a "shotgun" approach. The fluorescence intensity of the macrocycles can be modulated in two intriguing ways: enhancement by adding an oxidant and quenching by adding fullerenes.

Abstract ：
A class of side-chain type ferrocene macrocycles with a radially conjugated system is introduced in this study. The stereo configurations of these ferrocene rings were determined through single-crystal X-ray diffraction analysis. Notably, in the solid state, the ferrocene rings exhibit a distinctive herringbone stacking pattern imposed by a ferrocene-to-ring host-guest interaction. Through UV-vis absorption spectroscopy, electrochemical measurements, and theoretical calculations, valuable insights into the electronic properties of these rings were obtained. In addition, the single crystal of macrocycle A2B demonstrates a second-order nonlinear optical response. As a class of organometallic nanorings, this work holds great potential for further exploration in the fields of organometallic chemistry, molecular electronics, and host-guest chemistry. © 2024 The Authors.

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-HF 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 x 10(-6) M, LOQ = 1.03 x 10(-5) M, K-a = 5.83 x 10(5) M-1; and OH-: LOD = 1.36 x 10(-6) M, LOQ = 4.11 x 10(-5) M, K-a = 9.03 x 10(5) M-1). H-1 NMR titrations demonstrated that anion was recognized by receptor 1 through (C-H)(+)X- and C-HX hydrogen bonds, the binding process involve initial formation of hydrogen bond and followed by deprotonation.

Abstract ：
Here, we report the synthesis, structure, and single-molecule conductance of three o-carborane-based molecular wires (ortho-, meta- and para-CN) with multiple conduction channels. The effect of connectivity in target wires compared with the corresponding phenyl-centered wires was studied using the scanning tunneling microscope break junction (STM-BJ) technique and theoretical calculations. Interestingly, the three-dimensional structure in o-carborane-based wires can effectively promote the through-space transmission paths or the formation of stable molecular junctions compared to the corresponding phenyl-centered wires. Moreover, the significant conductance difference of o-carborane-based wires was due to the combination of multiple conduction channels and quantum interference. Understanding the effects of different bridging groups and anchor group substitution patterns provides guidelines for designing o-carborane-based multichannel molecular wires.

Abstract ：
Stimuli-responsive luminescence plays a crucial role in the development of mechanoluminescent materials. Here, we designed and synthesized four o-carborane-based aggregation-induced emission molecules, two of which, CB-Ph-P and CB-Ph-PAn, exhibited multiple solid-state fluorescence emissions. Upon mechanical stimulation, the recrystallization solid of CB-Ph-P caused a bathochromic shift in its fluorescence emission from 423 nm to 608 nm. Similarly, CB-Ph-PAn exhibits a transition in the fluorescence emission wavelength from 393 nm to 623 nm when in the solid state. In order to gain insight into the mechanism behind their luminescence behavior, we performed analyses including powder X-ray diffraction, photophysical properties, thermal properties, and single-crystal structure analysis. It is deemed that the polymorphism may be related to different weak interactions, packing modes and torsion angles.
