“…Derivates based on rhodamine are frequently used to detect Cu 2+ via Cu 2+ -induced spirolactam ring-opening and hydrolysis processes to produce a turn-on response [70,71]. In the past years, AIE-based probes have also been designed for Cu 2+ sensing and find applications in bioimaging [72][73][74][75].…”

Metal ions play important roles in biological system. Approaches capable of selective and sensitive detection of metal ions in living biosystems provide in situ information and have attracted remarkable research attentions. Among these, fluorescence probes with aggregation-induced emission (AIE) behavior offer unique properties. A variety of AIE fluorogens (AIEgens) have been developed in the past decades for tracing metal ions. This review highlights recent advances (since 2015) in AIE-based sensors for detecting metal ions in biological systems. Major concerns will be devoted to the design principles, sensing performance, and bioimaging applications.

Ratiometric fluorescent detection of Cu²⁺ based on dual‐emission ZIF‐8@rhodamine‐B nanocomposites

Zeolitic imidazolate framework-8 (ZIF-8) loading rhodamine-B (ZIF-8@rhodamine-B) nanocomposites was proposed and used as ratiometric fluorescent sensor to detect copper(II) ion (Cu 2+ ). Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray powder diffraction, nitrogen adsorption/desorption isotherms and fluorescence emission spectroscopy were employed to characterize the ZIF-8@rhodamine-B nanocomposites. The results showed the rhodamine-B was successfully assembled on ZIF-8 based on the π-π interaction and the hydrogen bond between the nitrogen atom of ZIF-8 and -COOH of rhodamine-B. The as-obtained ZIF-8@rhodamine-B nanocomposites were octahedron with size about 150-200 nm, had good water dispersion, and exhibited the characteristic fluorescence emission of ZIF-8 at 335 nm and rhodamine-B at 575 nm. The Cu 2+ could quench fluorescence of ZIF-8 rather than rhodamine-B. The ZIF-8 not only acted as the template to assemble rhodamine-B, but also was employed as the signal fluorescence together with the fluorescence of rhodamine-B as the reference to construct a novel ratiometric fluorescent sensor to detect Cu 2+ . The resulted ZIF-8@rhodamine-B nanocomposite fluorescence probe showed good linear range (68.4 nM to 125 μM) with a low detection limit (22.8 nM) for Cu 2+ combined with good sensitivity and selectivity. The work also provides a better way to design ratiometric fluorescent sensors from ZIF-8 and other fluorescent molecules. KEYWORDSCu 2 + , ratiometric fluorescent sensor, rhodamine-B, zeolitic imidazolate framework-8 biotoxicity, poor aqueous solubility and stability, etc. Nanomaterial fluorescent probes, especially the metal-organic frameworks (MOFs) or zeolitic imidazolate framework-8 (ZIF-8) based probes, are attracting more and more interest and are used for different applications due to their predictable pore sizes, considerable specific surface area, good encapsulation and hierarchical structures. [35][36][37][38][39] For example, carbon dots (CDs)@MOFs have been prepared to enhance fluorescence sensing. [40] A ratiometric type fluorescence sensor has two or more emission wavelengths, and the target content is usually quantified based on the relationship between the ratio of fluorescence intensities at two wavelengths and the concentration of the analyte. At the same time, this sensor mode enhances the dynamic response range by adjusting the change of intensity ratio, and establishes an internal standard to make it self-regulating, greatly weakening the effect some experimental conditions such as probe concentration, temperature, polarity, environmental pH, and stability. These experimental conditions are usually difficult to control in the experimental process. Moreover, as the concentration of analyte changes, the color of the ratio probe changes step-by-step, thereby enabling visual detection of the analyte, and semi-quantitative and qualitative analysis of the analyte can be achieved depending on the color of the ratio probe. [41,42] Therefore, the construction of rati...

Organic functional materials, including conjugated molecules and fluorescent dyes, have been intensely developed in recent years because they can be applied in many fields, such as solar cells, biosensing and bioimaging, and medical adjuvant therapy. Organic functional materials with aggregation-induced emission or aggregation-enhanced emission (AIE/AEE) characteristics have increasingly attracted attention due to their high quantum efficiency in the aggregated or solid state. A large variety of AIE/AEE materials have been designed and applied during the exponential growth of research interest in the abovementioned fields. Multiphenyl-substituted 1,3-butadiene (MPB), as a core structure that includes tetraphenyl-1,3-butadiene, hexaphenyl-1,3-butadiene and their derivatives, show a typical AIE/AEE feature and can be potentially used in all the above-mentioned fields. This review summarizes the design principles, the corresponding syntheses, and the structure-property relationships of MPBs, as well as their excellent innovative functionalities and applications. This review will be useful for scientists conducting chemistry, materials, and biomedical research in AIE/AEE-related fields.
