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.
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.
