Tetralactam macrocycle based aggregation-induced emission dots for selective detection of Fe3+ in water and drugs
Iron ion (Fe3+) is crucial for both biological organisms and the environment, and iron dyshomeostasis can lead to a variety of diseases and environmental issues. Therefore, the detection of Fe3+ is of significant importance across various fields. For this purpose, through the co-assembly of water-soluble tetralactam macrocycle H and 1,1,2,2-tetraphenylethylene (TPE), we prepared a new type of tetralactam macrocycle based aggregation-induced emission dots (AIE-dots), namely TPE@H. TPE@H exhibitted good water-solubility and allowed the water-insoluble TPE to aggregate and exhibit strong fluorescence emission in water. Furthermore, the fluorescence of TPE@H could be quenched by Fe3+ through the inner filter effect, making TPE@H a potential “turn-off” fluorescent probe for Fe3+ detection. TPE@H exhibited a limit of detection as low as 1 μM with high selectivity, and also retained good detection performance in domestic water, human serum, and even drugs, indicating its great potential for biological and environmental monitoring of Fe3+. This study not only provides a green and efficient method for detecting Fe3+, but also expands the approach for application of water-insoluble dyes in the aqueous environment.
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.
