Covalent C-C bonded macrocycle topologies have been attracting increasing attention owing to their structural diversity and various applications. However, the methods for constructing such structures are limited, with most relying on transition metal-catalysis or requiring stringent reaction conditions, highlighting the urgent need to explore innovative synthetic approaches. Hence, we report a stepwise Friedel-Crafts gridization catalyzed by BF 3 ⋅Et 2 O under ambient conditions and air atmosphere for the synthesis of the multi-grid topological nanostructures 2G-AG (30% yield) and 3G-AG (8% yield). Furthermore, the non-planar and structurally more complex multi-grid topologies, 2G-AG and 3G-AG, exhibit stronger excimer emission. This study provides a novel method for designing and synthesizing complex macrocyclic topological nanostructures connected by covalent bonds and with optoelectronic functionality.

Dyes and Pigments

染料和颜料涵盖染料、颜料及其中间体的化学和物理的科学和技术方面。重点放在着色物质本身的特性上，而不是它们的应用或它们可能应用的系统上。因此，该杂志接受关于染料、颜料和中间体的合成及其物理或化学特性的研究和评论论文，例如光谱、表面、溶液或固态特性，其制备的物理方面，例如沉淀，成核和生长，晶体形成，液晶特性，它们的光化学，生态或生物学特性以及颜色和化学成分之间的关​​系。但是，考虑的论文涉及着色剂应用的更基本方面以及着色剂与基材或介质的相互作用。该杂志将对涉及染料、颜料及其中间体的一系列学科的广泛工作者感兴趣，并为具有共同兴趣但活动领域多样化的研究人员提供一个平台，如化妆品、复印、染料和颜料合成、医学研究、聚合物等。

The journal "Dyes and Pigments" covers the chemical and physical sciences and technologies of dyes, pigments, and their intermediates. It focuses on the characteristics of the coloring substances themselves rather than their applications or the systems in which they may be applied. Therefore, the journal accepts research and review papers on the synthesis of dyes, pigments, and intermediates, as well as their physical or chemical properties, such as spectral, surface, solution, or solid-state characteristics, and the physical aspects of their preparation, including precipitation, nucleation and growth, crystal formation, liquid crystal properties, photochemical, ecological, or biological characteristics, and the relationship between color and chemical composition. Furthermore, the papers considered also address the more fundamental aspects of the applications of colorants and the interactions between colorants and substrates or media. The journal "Dyes and Pigments" is interested in a wide range of workers in various disciplines related to dyes, pigments, and their intermediates, providing a platform for researchers with shared interests but diverse fields of activity, such as cosmetics, photocopying, dye and pigment synthesis, medical research, and polymers.
