“…Generally, AIEgens are not emissive in the solution because the free-rotation of phenyl groups deactivates the photoluminescence intensity, whereas such AIEgens can increase the photoluminescence intensity drastically in the solid state owing to the restriction of intramolecular motion. Thus, over the last two decades, many papers have been published based on the AIEgen containing materials for solar cells, [36][37][38] organic light emitting diodes (OLEDs), [39][40][41][42] sensing applications, [43][44][45][46][47] photocatalysis, [48] and biomedical fields. [49][50][51] On the contrary, very limited papers were published based on the AIEgen-decorated porphyrins for fluorescence bioimaging, photodynamic therapy (PDT), photocatalytic hydrogen F I G U R E 1 Structures of AIEgens attached to porphyrin macrocycle evolution (PHE), solid state photoluminescence, electrochemiluminescence (ECL), and self-assembled studies.…”

An overview on AIEgen‐decorated porphyrins: Current status and applications

One of the major obstacles of porphyrins is the aggregation-caused quenching (ACQ) of photoluminescence due to the strong intermolecular π-π interaction of the planar porphyrin core in the solid state. However, ACQ leads to the nonradiative deactivation of the photoexcited states which results in short-lived charge-separated states and thus low photoluminescence and singlet quantum yields. This phenomenon would limit the utilization of porphyrins in near-infrared fluorescent bioimaging, photodynamic therapy, photocatalytic hydrogen evolution, electrochemiluminescence, and chiroptical applications. Hence, to address the ACQ property of porphyrins and enhance the performance of the above applications, a limited number of AIEgen-decorated porphyrins have been designed, synthesized, and tested for their applications. It has been found that the introduction of AIEgens, such as tetraphenylethylene, diphenylacrylonitrile, (3,6-bis-(1-methyl-4-vinylpyridinium)-carbazole diiodide, and iridium motif into the porphyrin core, transformed the porphyrins from ACQ to aggregation-induced emission (AIE) in their solid state due to the reduced strong intermolecular π-π stacking of porphyrins. Consequently, such porphyrins containing AIE features are employed as potential candidates in the above-mentioned applications. In this review, we summarize the AIEgen-decorated porphyrins which have been published to date, and also discuss the benefits of converting porphyrins from ACQ to AIE for enhanced performance within each application. As far as we know, there is no review that summarizes the structures and applications of AIEgen-decorated porphyrins to date. Therefore, we presume that this review would be helpful to design more efficient AIEgen-decorated porphyrins for a wide range of applications in the future.

“…Compared with this traditional analytical equipment, the fluorescent and/or colorimetric techniques are more appropriate, competent, and alluring for the sensitive on-site detection of NACs and VOCs due to their high sensitivity and selectivity, low cost, simplicity, rapid responsiveness, high signal-to-noise ratio, and real-time detection. [15,16] In this method, the initial emission intensity of the fluorescent probe itself is perturbed (quenched or enhanced) upon binding with analytes which can bring about fluorescence "turn-off" or "turnon" signals. These sensing techniques are very much handy to monitor these organic pollutants in several environmental specimens e. g., air, natural waterbody, and soil samples.…”

Fresh air and clean water are essential constituents for the human population as well as for fauna and flora. Owing to the extreme toxicity of NACs and VOCs in physiological systems and their widespread presence in the environment, serious mitigation is required. The innovation of chemosensors for these two types of harmful organic contaminants (NACs i. e., nitroaromatics, and VOCs i. e., volatile organic compounds) have unfolded as a key research topic in recent decades, garnering a lot of attention due to their environmental, industrial and biological importance. In recent years, there has been a significant amount of research on both NACs and VOCs chemosensors. This Review article has recapitulated the latest development of fluorescent chemosensors especially small molecular frameworks from 2015 to 2022, for NACs and VOCs which has been discussed individually. In addition, the detection of NACs and VOCs on multiple platforms with a special focus on their mechanistic exploration, as well as their probable applications in natural water body specimens, vapor phase detection, and paper strip analysis have also been discussed.

“…In contrast, fluorescent sensors exhibit significant benefits, including high sensitivity, decreased cost, and simplified operation, which have attracted great research interest and are constantly evolving for amine detection. 12 Covalent organic frameworks (COFs) are periodic organic porous materials with crystallinity that have sparked considerable interest due to their adjustable characteristics and structural durability. 13,14 Through the elaborated design of precursors with different electronic effects and assembly by different covalent bonds, the structures and photophysical properties of COFs can be modulated at the atomic level.…”

Amine determination is crucial to our daily life, including the prevention of pollution, the treatment of certain disorders, and the evaluation of food quality. Herein, a mixedlinkage donor−acceptor covalent organic framework (named DSE-COF) was first constructed by the polymerization between 2,4dihydroxybenzene-1,3,5-tricarbaldehyde (DTA) and 4,4′-(benzo-[c][1,2,5]selenadiazole-4,7-diyl)dianiline (SEZ). DSE-COF displayed superior turn-on fluorescent responses to primary, secondary, and tertiary aliphatic amines, such as cadaverine, isopropylamine, sec-butylamine, cyclohexylamine, hexamethylenediamine, di-n-butylamine, and triethylamine in absolute acetonitrile than other organic species. Further experiments and theoretical calculations demonstrated that the combination of intramolecular charge transfer (ICT) and photoinduced electron transfer (PET) effects between the DSE-COF and aliphatic amines resulted in enhanced fluorescence. Credibly, DSE-COF can quantitatively detect cadaverine content in actual pork samples with satisfactory results. In addition, DSE-COF-based test papers could rapidly monitor cadaverine from real pork samples, manifesting the potential application of COFs in food quality inspection.
