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 ：
Two o -carborane based tetraphenylethene (TPE) cationic cyclophanes O1 4PF6 and O2 4PF6 were synthesized through an SN 2 reaction. Their structures were confirmed both possessing Z-shaped cavities in single crystal analysis. The optical properties of these macrocycles were systematically investigated using UV-vis spectroscopy and fluorescence techniques. It is worth noting that the introduction of a methoxy group to the TPE unit enables the synthesis of a near-infrared-emitting macrocycle O2 4PF6 . The recognition behaviors of these two macrocycles towards nucleotides were investigated using various techniques including fluorescence titration, UV-vis titration, and transmission electron microscopy (TEM). Interestingly, these cyclophanes exhibited aggregation-induced emission (AIE) effects in water or under the induction of nucleotides.

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 ：
Both synthesis and DFT calculation of [3 + 2] cycloaddition reaction (32CA) of quinolone-5,8-dione with 1,3dipole CF3CHN2 are studied. The focus of this work is to study the orbital interactions of this reaction by using molecular orbital tracing (MOT) method. MOT result shows that both quinolone-5,8-dione and CF3CHN2 use three electrons occupied molecular orbitals (MOs) to interact with each other, and the evolutive courses of the six molecular orbitals of reactants (initial MOs) to six electrons occupied molecular orbitals of product (final MOs) are given in this work. Three of the six initial MOs can evolve as final MOs directly, but rest of them need to go through media orbitals to complete the evolution. Perhaps the role of the media orbitals is to enable the reaction to proceed concertedly. APT charges analysis and changes of bond lengths during the reaction are also afforded in this work, and the result shows that the reaction begins with a nucleophilic attack of CF3CHN2 on quinolone-5,8-dione. Accompanying with the attack, negative charge transfers from CF3CHN2 to a carbon atom of quinolone-5,8-dione, then the carbon atom attacks nitrogen atom of CF3CHN2 to complete the cycloaddition. At last, a mechanism and a diagram of the molecular orbital interactions of the reaction are given.

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 ：
Development of earth-abundant, low-cost and easily synthesizable catalysts for the semi-hydrogenation of acetylene is urgently needed. Here, we have systematically investigated the structure, electronic properties, hydrogen dissociation, and acetylene semi-hydrogenation activity and selectivity of poly(heptazine imide) (PHI) loaded with different sizes of Cun (n = 1,2,4,13) clusters (Cun/PHI) by density functional theory calculations. The results show that Cu4/PHI with tetrahedral configuration has a better hydrogenation activity in the acetylene semi-hydrogenation reaction with H adsorbed in the vicinity of acetylene and subsequent intermediates in a nonbridge position, resulting in a smaller hydrogenation energy barrier. In addition, the top Cu atom transfers a large number of electrons to the bottom Cu atoms and PHI, and only a small number of electrons transfer to ethylene, resulting in weak adsorption of ethylene and easy desorption, which makes it good selectivity and therefore it can be used as a candidate catalyst for the semi-hydrogenation of acetylene. This study provides insights into the design of catalysts with suitable size clusters loaded on carbon nitride materials for efficient acetylene semihydrogenation reactions.
