将聚集诱导发射（AIE）分子转化为功能材料可以极大地调节其荧光性质，并扩展其相关的潜在应用。在这里，我们展示了一种简单的策略，通过将AIE分子限制在金属有机框架（MOFs）的纳米通道内来调节AIE分子的荧光特性。将具有pH依赖性发光的AIE分子（4，4 ′-（肼-1，2-二亚甲基双（亚甲基））双（3-羟基苯甲酸），HDBB）成功地整合到UiO-66中，得到UiO-66双HDBB复合物，同时通过主客体过程保持晶体结构。HDBB的荧光性质可以通过独特的纳米空间限制效应来调节。此外，UiO-66-HDBB还可作为一种灵敏、选择性强的荧光探针用于水溶液中Cu ~（2+）的检测。本研究为制备性能可调的高性能AIE基发光材料提供了一种简便的方法。
Transformation of aggregation induced emission (AIE) molecules into functional materials can greatly tune their fluorescence properties and expand their related potential applications. Here, we demonstrate a facile strategy to modulate the fluorescence properties of AIE molecules by confining them within the nanochannels of metal–organic frameworks (MOFs). AIE molecules (4,4′-(hydrazine-1,2-diylidene bis(methanylylidene)) bis(3-hydroxybenzoic acid), HDBB) with pH-dependent emission were successfully integrated into UiO-66 resulting in a UiO-66⊃HDBB complex while maintaining the crystal structure by the host–guest process. The fluorescence properties of HDBB can be modulated by virtue of the unique nanospace confining effect. Furthermore, UiO-66⊃HDBB was used as a sensitive and selective fluorescent probe for Cu2+ detection in aqueous solution. This study provides a facile strategy for the construction of high performance AIE based luminescent materials with adjustable properties for potential applications.
