Abstract Chirality, a fundamental principle in chemistry, biology, and medicine, is prevalent nature organisms. Chiral molecules, such as DNA, RNA, proteins, are crucial biomolecular synthesis, well the development of functional materials. Among these, 1,1′‐binaphthyl‐2,2′‐diol (BINOL) stands out for its stable chiral configuration, versatile functionality, commercial availability. BINOL widely employed asymmetric catalysis This review mainly focuses on recent research over past five years concerning use derivatives constructing macrocycles cages. Their contributions to luminescence, enantiomeric separation, transmembrane transport, were examined.

Abstract Carbon materials are of great significance in state‐of‐the‐art electrochemical CO 2 reduction (ECR) as key components such electrocatalysts, gas diffusion electrodes, and current collectors. Notably, dimensionalities carbons related manipulations play vital roles boosting ECR performance, e.g., mass/charge transfer dynamics, exposure active sites, reaction space, product's Faradaic efficiency/selectivity, durability. Here, recent endeavors dimensionality engineering toward advanced carbon‐based for is first summarized, including pure (e.g., carbon nanotube graphene) composites, highlight the dimensionality‐dependent properties performance. Various strategies referring to modulation integration have been top‐down, bottom‐up, soft chemical approaches. Design principles dimensionality‐varied elaborated, impacts surface chemistry functional group, wettability, electronic structure) on kinetics product‐targeted mechanisms also scrutinized. Some insights into how manipulation elevates performance acceleration, kinetics, product selectivity provided. At last, a perspective challenges future development discussed. This review aims at providing guidance customizable construction with dependence green energy‐saving electrosynthesis systems.

Abstract A negatively curved aza‐nanographene (NG) containing two octagons was synthesized by a regioselective and stepwise cyclodehydrogenation procedure, in which double aza[7]helicene simultaneously formed as an intermediate. Their saddle‐shaped structures with negative curvature were unambiguously confirmed X‐ray crystallography, thereby enabling the exploration of structure–property relationship photophysical, electrochemical conformational studies. Moreover, assembly octagon‐embedded aza‐NG fullerenes probed fluorescence spectral titration, record‐high binding constants ( K =9.5×10 3 M −1 C 60 , =3.7×10 4 70 ) found among reported polycyclic aromatic compounds. The tight association further elucidated diffraction analysis their co‐crystal, showed formation 1 : complex substantial concave‐convex interactions.

Strained carbon nanohoops exhibit attractive photophysical properties due to their unique π-conjugated structure. However, incorporation of such into the pincer ligand metal complexes has rarely been explored. Herein, a new family highly strained cyclometalated platinum(II) synthesized and characterized. Strain-promoted C–H bond activation observed during coordination process, Hückel–Möbius topology random-columnar packing in solid state are found. Transient absorption spectroscopy revealed size-dependent excited nanohoops. Moreover, have successfully employed as active materials fabrication solution-processable resistive memory devices, including use smallest nanohoop for binary memory, with low switching threshold voltages ca. 1.5 V, high ON/OFF current ratios, good stability. These results demonstrate that strain structure can be an effective strategy fundamentally fine-tune reactivity, optoelectronic, properties.
