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 ：
The preparation of polycyclic aromatic hydrocarbons (PAHs) by the Scholl reaction is typically performed by using superstoichiometric oxidants. Herein, we develop an electrochemical continuous-flow Scholl reaction to access PAHs that features a reduction in the use of supporting electrolytes and easy scale-up without changing the reaction conditions and setups. This reaction allows the synthesis of distorted PAHs containing three [5]helicene units that possess intriguing electronic and optical properties.

Abstract ：
An electrochemical intramolecular 5-exo-dig aza-cyclization of 2-alkynylbenzamides and subsequent nucleophilic fluorination have been developed to afford the highly selective synthesis of mono- and trifluorinated isoindolin-1-one derivatives. This work demonstrates the unique capability of synthetic electrochemistry in controlling reaction selectivity through the applied electrolytic parameters. In addition, the obtained monofluorinated 3-methyleneisoindolin-1-one (19) displays interesting photophysical properties that are not observed in its nonfluorinated analog.

Abstract ：
Organic nonlinear optical materials have attracted much attention due to their large nonlinear optical coefficients and ultrafast response speeds, as well as their potential applications in optical limiting (OL). Among them, nonlinear optical materials with phenanthrenone as the backbone are consistently understudied. We have successfully realized the transformation of organic small molecules in the nonlinear optical direction by replacing the carbonyl group on the structure of phenanthrenone with a malononitrile group. The nonlinear optical properties of CN-2 were investigated under different excitation conditions at 532 nm and the kinetic process of nonlinear optics was analyzed by transient absorption spectroscopy. In addition, we also investigated the OL properties of CN-2 , and the OL experiments showed that CN-2 with a lower OL threshold has superior OL properties than C 60 .

Abstract ：
Sulfonimidoyl fluorides, the aza-bioisostere of sulfonyl fluorides, are emerging as a promising link -age agent in the sulfur(VI) fluoride exchange reaction (SuFEx). However, conventional synthetic approaches typically require the use of either unstable sulfonimidoyl chlorides, toxic and corrosive sulfur fluorides, or expensive electrophilic fluorinating agents. Herein, we report an electrochemistry-en-abled oxidative nucleophilic fluorination of readily available and bench-stable sulfinamides using a com-mercially available and easy-to-handle triethylamine trihydrofluoride. With other nucleophilic agents, this electrochemical approach also serves as a general approach to diverse sulfonimidoyl derivatives, including sulfonimidoyl azides and acetates.

Abstract ：
A series of sila-annulated phenanthrene imides were synthesized through a three-step synthetic route, which represent a hybrid class of biphenyl-based pi-conjugated molecules incorporating an imide unit and silole. A comprehensive investigation of their structural, photophysical, and electronic properties was studied by experiment and theoretical calculations. Notably, sila-annulated phenanthrene imides with significant aggregation-induced emission (AIE) properties were observed.

Abstract ：
Two o-carborane based tetraphenylethene (TPE) cationic cyclophanes O1·4PF6 and O2·4PF6 were synthesized through an SN2 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. © 2024

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.
