Abstract

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 BF₃·Et₂O 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.

基于逐步弗里德尔-卡夫斯反应的多网格拓扑纳米结构的迭代合成

C-C 键共价大环拓扑结构因其结构的多样性和各种应用而日益受到关注。然而，构建此类结构的方法十分有限，大多数依赖于过渡金属催化或需要严格的反应条件，这凸显了探索创新合成方法的迫切需要。因此，我们报告了一种在环境条件和空气气氛下由 BF3-Et2O 催化的逐步 Friedel-Crafts 格化方法，用于合成多格拓扑纳米结构 2G-AG（产率 30%）和 3G-AG（产率 8%）。此外，非平面且结构更复杂的多网格拓扑结构 2G-AG 和 3G-AG 表现出更强的准分子发射。这项研究为设计和合成由共价键连接并具有光电功能的复杂大环拓扑纳米结构提供了一种新方法。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
