摘要

报道了一种四苯基乙烯（TPE）取代的无环葫芦[n]脲（CB[n]）。寄主是通过在无环CB[n]芳香壁上安装4个TPE基团合成的。所得到的TPE修饰的无环CB[n]表现出聚集诱导发射（AIE），与TPE单体相比，具有更高的量子产率。TPE取代的无环CB[n]在水中和试纸上对Fe3+离子表现出选择性荧光响应。该荧光传感器被证实可用于铁离子的定量检测。

Tetraphenylethylene substituted acyclic Cucurbit[n]uril: Aggregation-Induced emission and selective detection of Fe(III) ion

This paper reports a tetraphenylethylene (TPE) substituted acyclic cucurbit[n]uril (CB[n]). The host is synthesized by installing four TPE moieties on acyclic CB[n] aromatic walls. The resulting TPE modified acyclic CB[n] shows aggregation induced emission (AIE), and possesses enhanced quantum yield compared to the TPE monomer. TPE substituted acyclic CB[n] shows selective fluorescence response to Fe³⁺ ion in water and on a test paper. This fluorescent sensor is confirmed to be used for the quantitative sensing of ferric ion.

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.
