Monodentate AIEgen Anchored on Metal‐Organic Framework for Fast Fluorescence Sensing of Phosphate

et al. 2020

Metal-organic frameworks | Fluorescent probes | Phosphate | Monodentate ligand | AIEgen Herein, a novel sensor (TPE-UiO-66) was designed via anchoring monodentate tetraphenylethylene (TPE) onto UiO-66 framework. The combination of the distinct aggregation-induced emission (AIE) of TPE and the easy replacement of monodentate linker by guest phosphate, makes TPE-UiO-66 an ideal platform for sensing HPO 4 2-. Experimental results indicate that TPE-UiO-66 can selectively sense HPO 4 2from other common anions. The limit of detection (LOD) can reach to 5.56 μmol•L-1 and more importantly, TPE-UiO-66 also exhibits an ultra-fast equilibrium response of 2 min, far faster than those of other sensors especially for UiO-66-NH 2. The combination of experimental analysis and density functional theory (DFT) calculations demonstrates that the high selectivity, high sensitivity and fast response of HPO 4 2detection by TPE-UiO-66 can be attributed to the stronger coordination interactions of HPO 4 2with Zr-O cluster of UiO-66 than that of TPE molecule. This study not only provides a potential probe for phosphate, but also represents a novel strategy to design stimuli-responsive fluorescent MOF-based sensors via using monodentate AIEgens.

Multiple Hydrogen Bonds Promoted ESIPT and AIE‐active Chiral Salicylaldehyde Hydrazide

et al. 2018

The simpler, the better! A series of simple and highly fluorescent salicylaldehyde hydrazide molecules (41 samples) have been designed and prepared. Even though these soft materials contain a very small π‐conjugated system, they can go through multiple intramolecular and intermolecular hydrogen bonds promoted excited‐state intramolecular proton‐transfer (ESIPT) to display strong blue, green, yellow, and orange aggregation‐induced emission (AIE) with large Stokes shifts (up to 184 nm) and high fluorescence quantum yields (Ф up to 0.20). Unusual mechanochromic fluorescence enhancements are also found in some solid samples. Through coordination, hydrogen and halogen bonds, these flexible molecules can be used as Mg2+ (Ф up to 0.46) probes, universal anion (Ф up to 0.14) and unprotected amino acids (Ф up to 0.16) probes, and chiral diamine (enantiomeric selectivity and Ф up to 0.36 and 0.062, respectively) receptors. Combining their advantages of AIE and biocompatibility, these low cytotoxic dyes have potential application in living cell imaging. Furthermore, the effects of different functional groups on the molecule arrangement, ESIPT, AIE, probe, and chiral recognition properties are also examined, which provide a simple and bright paradigm for the design of multiple‐stimuli‐responsive smart materials.
