摘要

叠氮化合物是一类重要的化合物,其荧光发射取决于芳香族支架中的取代基,与溶剂有关。它们价格低廉、易于合成、性质稳定,非常适合多种应用。与大多数其他 AIE 荧光体不同,AIE 活性叠氮衍生物的芳香单元是通过可旋转的 NN 键而不是 CC 键连接的。它们的衍生物已被广泛应用于制药、给药、有机金属、光电子学、染料等领域,最重要的是在一些传感应用中。本综述概述了 AIE 活性偶氮分子领域的最新发展及其作为化学传感器在检测各种分析物中的应用。综述讨论了检测金属离子(Cu2+、Zn2+、Al3+、Fe3+、Cr3+、Hg2+、UO22+ 等)、阴离子(F)、阳离子(Cu2+、Zn2+、Al3+、Fe3+、Cr3+、Hg2+、UO22+ 等)的不同化学传感策略。)、阴离子(F、CN、ClOO、ONOO、HSO3)、生物分析物(原胺/肝素、HSA/BSA、神经氨酸酶、-内酰胺酶、-半乳糖苷酶等)、小分子(硫醇、肼、过氧化氢)的检测方法,重点介绍过去五年的发展情况。综述还重点介绍了氮基系统在成像、超分子主客体识别、AIE 聚合物和 COFs/MOFs 等方面的应用进展。

Aggregation-induced emission-active azines for chemosensing applications: a five-year update

Aggregation-induced emission-active azines for chemosensing applications: a five-year update

Azines are an important class of compounds that display solvent-dependent fluorescence emission depending upon the substituents in the aromatic scaffolds. They are affordable, easy to synthesize, stable, and well-suited for numerous applications. Unlike most other AIE fluorophores, aromatic units of AIE-active azine derivatives are bridged by rotatable N–N bonds rather than C–C bonds. Their derivatives have been widely used in pharmaceuticals, drug delivery, organometallics, optoelectronics, dyes, etc., and most importantly in several sensing applications. This comprehensive review encapsulates the recent developments in the field of AIE-active azine molecules and their applications as chemosensors in the detection of various analytes. The review discusses the different chemosensing strategies involved in the detection of metal ions (Cu2+, Zn2+, Al3+, Fe3+, Cr3+, Hg2+, UO22+, etc.), anions (F, CN, ClO, ONOO, HSO3), small molecules (thiols, hydrazine, hydrogen peroxide), and bio-analytes (protamine/heparin, HSA/BSA, neuraminidase, β-lactamase, β-galactosidase, etc.) with a focus on the development in the last five years. The review also highlights the advancements in azine-based systems for their use in imaging, supramolecular host–guest recognitions, AIE polymers, COFs/MOFs, etc.
