AIE-active metal–organic frameworks: facile preparation, tunable light emission, ultrasensitive sensing of copper(ii) and visual fluorescence detection of glucose

Abstract

<p>A series of LMOFs with AIE and ESIPT properties, tunable emissions and large Stokes shifts has been facilely synthesized by binding AIEgens with nanoscale ZIF-8 to realize sensitive sensing of copper(<sc>ii</sc>) and visual fluorescence detection of glucose.</p>

Fibrous aggregates: Amplifying aggregation-induced emission to boost health protection

“…The biosensing mechanism is known by the enzyme catalysis of glucose to formation of H 2 O 2 [ 57 ]. Compared with instrumental analysis systems, colorimetry/fluorometry glycosuria test strips are easy-visualized and cost-effective, benefitting for family and individual self-testing [ [58] , [59] , [60] ]. Chao et al designed poly (amic acid) (PEBA) bearing AIE units and oligoaniline segments, which was utilized as a dual-response sensor (colorimetric and fluorometric) followed by electrospinning (combined with PAN) ( Fig.…”

Recent advances in AIEgen‐based crystalline porous materials for chemical sensing

“…Liu and coworkers used the novel AIEgens ((E)‐2‐((2‐aminophenylimino)methyl)phenol, APMP) and its derivatives as the guest luminescent species to prepare a series of AIE‐active LMOFs. [ 40 ] Different from previously discussed structures in which AIEgens were decorated on the framework via strong covalent or coordinate bonds, AIEgens were incorporated in ZIF‐8 via weak host–guest interaction. This provided a simple large‐scale synthesis method of AIE‐active MOF and the fluorescence features of AIE‐active MOFs could be tailored through varying the substituents on APMP molecules.…”

Zinc (II) and AIEgens: The “Clip Approach” for a Novel Fluorophore Family. A Review

“…Xiaoqing Chen and coworkers in 2020 [ 153 ] reported a series of AIE-active LMOFs with good photostability and excellent dispersibility. The emission of the LMOFs could be tuned by varying the substituents on AIEgens.…”
